AutoCAD Inventor :: Multiple Identical ILogic Sub-assemblies With Different Parameters
Jul 17, 2013
iLogic code question concerning how Place iLogic Component and retain the ability to push parameters from the subassemblies to the parts after being renamed.
I have ASSEMBLY.iam containing:
SUBASSEMBLY-01:1.iam
SUBASSEMBLY-02:1.iam
and sometimes SUBASSEMBLY-02:2.iam
each SUBASSEMBLY.iam contains PART1.ipt and PART2.ipt which have variable LENGTH and WIDTH. LENGTH and WIDTH are entered manually at the SUBASSEMBLY.iam and are infinitely variable.
To transfer the parameters I'm using iLogic code in the SUBASSEMBLY:
Parameter("PART1.ipt", "LENGTH")=LENGTHParameter("PART1.ipt", "WIDTH")=WIDTHParameter("PART2.ipt", "LENGTH")=LENGTHParameter("PART2.ipt", "WIDTH")=WIDTH
Issue 1: When I place the SUBASSEMBLY as an iLogic Component, the parts are renamed to PART1-01.ipt which renders my Parameter transfer useless. What am I missing on writing this code so it can find the new part name?
Issue 2: I like the automatic renaming that happens with Place iLogic Component. Is there a better way to handle this automatically through Place Component -> Save & Replace?

i have an assembly with 100+ parts that i have to show in my parts list.
my question is :
how can i add identical sheets showing identical view of the assembly but the ist page will show the first 50 parts and the second page will show the rest of the part list?

I got here on in my templates, two types of weight - net and gross. I've changed the main property MASS of each PART to be the GROSS weight, so when i have one assembly i always get the total gross weight.
And when i wanna get the NET, I open the BOM, show the proper column with this net weight and then export do XLS to sum all of then..
Now the doubt is, to get the things easier, is there a way to put some code in the assemblies, that could sum all the properties "X" from each part and sub assemblie to get the total net weight ?

i placed an ilogic component (wich i use as a template to later change dimentions) into an assembly file after changing dimentions i placed the same "template" ilogic component into the assembly but when i want to change something on the second component it also changes the first one and that only happens with only one feature of the component the other features work fine.

I'm new in use of iLogic and tried to use it by myself (and internet). But I have some difficulties.
Here is the open point, I wold like to create an assemblies with different length (and also some different part inside).
So I made some iLogic rules to make a configuration of my .iam with length selection.
I made rules to show or hide parts with is linked to the proper length.
I made rules to switch from a positional representation to another one and do the same for level of details representation and for view representation.
All is good in my .iam.
My problem is comming now. When I would like to put my .iam in a .idw in several views (corresponding to different length), my views are the all the same. I can't see one length per view even if I select the proper representation, the proper position and the proper level of detail.
At the end, all this work is to have all views length to be able to make in one drawing all length block in autocad.

I'm new in iLogic. I started making an assembly where it has a form where I put the dimension and iLogic controls the subparts including a frame generated profiles (in this case, iassembly don't work with FG).<br><br>The problem is: In the Larger assembly, I also put an iLogic and a form where I want this sub assemblies (this is the assembly mentioned above) to be driven by the parameters I will input on this large assembly. I don't know how to handle this but what I want is to:<br><br>1. I need that when I place this sub assembly there will be a form that will popup during the placement like when I put a bolt on content center.<br>2. Save as a new number and when the set of parameters exist on the previous large assembly it will notify that the sub assembly exist.<br><br>is this possible?

My question is regarding the proper workflow within Inventor. We are currently using 2013 Pro.
I am trying to develop an Assembly that will take linked excel values and have the assembly repond to the user's input. This spreadsheet is to be general in form and is to be re-used for different projects. Right now, the excel values are linked to a master assembly file. This master file has a few iLogic rules to handle the user's input and to pass particular parameter values to the iAssemblies (read sub-assemblies). The iAssemblies are not that complex, but they are taking parameter values from the master, and using iLogic within the isub-assembly to choose the iAssembly member based on the parameter value.
Problem one:
There seems to be a problem with changing the iAssembly member. I have stabilized the iAssembly within the master Assembly. The isub-assembly does not update unless I open the isub-assembly file. In both the isub-assembly and the master assembly, I update at the end of each rule, and I trigger the rules after any parameter change.
The questions are:
Since there are 123 members (so far) in each of the 2 iAssemblies within the Master Assembly, do I really have to test the parameter 123 times to assign a particular iAssembly member? Or is there a more concise way to do this?
We are not using Vault yet, but with described workflow, will we have problems when we do migrate to a vault environment?

I'm running Invenor 2013 and I'm trying to figure out a way to rename my components from an iLogic assembly when placed in a new assembly.
Right now when I start a new assembly, then place an iLogic component it names everything "Part-01," Part1-01" and so on for all of the variable components.
What I'd like to do is write a rule that when placing my iLogic component it will name it based on the filename of the new assembly that I've created. "Part-New Assmebly," "Part1-New Assembly" and so on.

I'm having some difficulties with iLogic and reference parameters.
I have made a tube with a weird shape and I want to measure the longest length. So I have to cut the tube in a certain angle in relation with the center to measure the length.
The problem is that this angle is really hard to calculate.
So I tried making a rule where I can make my angle shift x degree and then measure the longest length. If the measurement is larger the previous measurement the angle will shift x degree again until the measurement is smaller than the previous.
So I made my starting angle 0 degree, I know this is for a fact not the longest length. And then I tried this rule. (before making a While rule).
And I noticed that on screen the measurement changes. But the reference - parameter stays the same. So it gives me the measurement on the starting angle & after rotating it again gives me the starting angle.
How can I get the parameter to update itself in between?
Dim measurement_length As DoubleDim measurement_length2 As DoubleMessageBox.Show("Start angle ", "My iLogic Dialog", MessageBoxButtons.OK, MessageBoxIcon.Asterisk, MessageBoxDefaultButton.Button1)angle_measurement_spec = 0RuleParametersOutput()InventorVb.DocumentUpdate()measurement_length = [code].....

I would like to save parameters marked as Key to an XML-file (from an Inventor addin, VB.NET):
Dim addIn As ApplicationAddIn = m_inventorApp.ApplicationAddIns.ItemById("{3bdd8d79-2179-4b11-8a5a-257b1c0263ac}") 'iLogic addin addIn.Activate() Dim iLogicAddin As Object = addIn.Automation iLogicAddin.ParametersXmlSave(invDoc, "c: emp ext.xml", iLogicAddin.XmlSaveOption.KeysOnly)
This doesn't run: "Public member 'XmlSaveOption' on type 'iLogicAutomation' not found."
The documentation says:
Autodesk.iLogic.Interfaces.IiLogicAutomation.ParametersXmlSave(Inventor.Document,System.String,Autodesk.iLogic.Interfaces.XmlSaveOption)
What is the correct syntax to get the XmlSaveOption?

In the attached file there is a User Parameter, "Antal_ledekasser". Inventor has calculated its value to 2.
If you do the math by hand then you see the value should be 5.
Rebuild doesn't force recalculation.
There is an iLogic rule in the part, but this also fails to force recalculation:
iLogicVb.UpdateWhenDone=True
InventorVb.DocumentUpdate()
ThisDoc.Document.Rebuild2
ThisDoc.Document.Update2
Manual work around is to change the formula, then the value is recalculated.
iLogic work around is to change a parameter-value - and run the rule TWICE.
Question: How do I force a real rebuild, that actually wil recalculate parameter-values the first time I run the iLogic rule?
Background: The attached file is a little subset of the skeleton in a large assembly that is controlled by iLogic. The rules are placed in the topassembly, and writes vaules to the skeleton-file.
After writing values to skeleton-parameters I try to force them through with this iLogic
RuleParametersOutput()
InventorVb.DocumentUpdate()
iLogicVb.RunRule("Skeleton", "Update")
Later in the process I use calculated values to decide which components should be active. But my logic fails because my decisions are made on faulty values.
I did manage to get the updating work in 2011. But after migrating to 2012, it seems impossible to have it update correct. The user has to run rules several times, and doing manually updates to get a correct model.

I want to export reference parameters to an excel table using i-Logic
I found the function GoExcel.CellValues("filename.xls", "Sheet1", "A2", "A10") = MultiValue.List("d0")
It looks like the syntax calls for the file location and name if the xls file is not open and if open is not supposed to be required.
I have entered it both ways and with and with out the target file open and with the function GoExcel.Open("pathFilename.xls","sheet1") and continue to get the error:
we couldn't find C:AbellAbell VaultWorkSpaceDEVELOPMENTAC100-0100MRLTEST Table.xls. Is it possible it was moved, renamed or deleted?
Also, I was expecting that to fill in the sheet cell's would be MultiValue.List("d0","d1","d2")
but the system give me an error that says
Error on Line 3 : Overload resolution failed because no accessible 'List' accepts this number of arguments.
See below
GoExcel.Open("C:AbellAbell VaultWorkSpaceDEVELOPMENTAC100-0100MRLTEST Table.xls", "AC-100-0101003-TEST")GoExcel.CellValues("C:AbellAbell VaultWorkSpaceDEVELOPMENTAC100-0100MRLTEST Table.xls", "AC-100-0101003-TEST", "A2", "A10") = MultiValue.List("d194_A")GoExcel.Save

I am trying to enter some material ordering info into an external spreadsheet, and have that info reflected in a text box within an idw drawing file.
My method is as follows:
Obtain a numerical value (250) from an external Excel spreadsheet (sample.xlsx).Assign this value to a parameter (abc) in an idw file (Materials Ordering.idw).Insert parameter abc I made into a text box within the same idw file.
I made a set_parameters rule, and the ilogic text of the above example is as follows:
'Open File and Scan line - Part = Impeller Casing Flange
i = GoExcel.FindRow("sample.xlsx", "Sheet1", "Part", "<=", "Impeller Casing Flange")
'abc = Material Width
abc = GoExcel.CurrentRowValue("Material Width")
I had no problems with the first two steps, after checking the parameters I could see that parameter abc is being updated successfully.
However, I am having trouble with the third step. In the format text dialog box, I can see a drop box for components, but I can't find a reference to the idw file in there.
My question is, am I going the wrong way about this? Should I have assigned the parameters to a component instead of the idw file?

I am looking for information on the option parameters, any documentation?
I found some code to query what parameters there are (Rule: GetTranslatorOptions), just not sure what the enumerations are for some.
Specifically: ExportUnits, Resolution
Using Rule:ExportSTL
I have changed the Export Units from 1 to 4 and do not see any change to the STL ASCII output.. not sure what this parameter does... Expected it to be an enumeration of the drop-down box that you see during "manual" exporting.

I have this little iLogic snippet that writes out the name and value of all parameters in active document.
doc = ThisDoc.Documentparams = doc.ComponentDefinition.Parametersnames = New List(Of String)values = New List(Of String)For Each param In paramsIf Len(param.Name)>4 Thennames.Add(param.Name)values.Add(param.Value.ToString)ElseEnd IfNextMultiValue.List("ParamsList") = namesMultiValue.List("ParamsValues") = valuesGoExcel.CellValues("COVER.DEFAULT.PARAMS.xlsx", "Sheet1", "A2", "A400") = MultiValue.List("ParamsList")GoExcel.CellValues("COVER.DEFAULT.PARAMS.xlsx", "Sheet1", "B2", "B400") = MultiValue.List("ParamsValues")GoExcel.SaveGoExcel.Close
The problem is it ignores the parameter's units and assumes cm for length and rad for angular. I need another nested IF - Then that says:
IF param.Values.'UnitType' is "in" THEN
param.Value = param.Value/2.54
Else If param.Values.'UnitType' is "deg" THEN
param.Value = param.Value*360/2/3.14159
End If
I just do not know the syntax or proper method.

I want to import the parameters from the .ipt file into the .iam file using a rule from iLogic (unless there is another way to do it?)
I pinched the code from the example hand rail iLogic part that comes with inventor and tweaked it to suit. After inputting the code shown in the image, when I click OK I get a 'fatal error' of some sort.

Is there a standard command or command sequence that allows for the changing of a parameter, say length, of a component from within an assembly. I'm looking to compile a code that allows for a template to be created, then that template will do changes based on text box input and then save out the modified parts with new part numbers.

I have a spring that is used in multiple assemblies and in each assembly the compressed length is different. Plus the amount of compression is different.
What is the best way to model the spring so if I change the WD or OD, etc. all assemblies would update?
I tried adaptive, but that seemed to limit the relationship to a one-to-one not a one-to-many.
If I used iPart or the spring was derived from a table, where the OD & WD were constant, would the assembly models change when I changed these values?

In my company there are a lot of standard parts with variations. An object can have for example a left and a right variation, or can have three a different heights. I've created and iAssembly with the different variations, in which every member has a different part number. I'd like to make an overview drawing containing all the variations of that object, so the user can easily see the options and can choose the one he wants. On the sheet I'd like to have views of all the different members of the iAssembly, plus a table of all the members with their part number. It was no problem to create the views and the table. But I have two other questions.
1. I want to show the name of the Assembly with the view. So I'd to have in the view a text with the description of the Assembly-member, which is linked with the Assembly. I've tried to use a balloon to tag the assembly, but this only balloons the parts of the assembly. (How) can I do this for the whole of the assembly?
2.When I make an overview of all the columns we use, I'd like to align all the views at the bottom of the view, so you can see that all the columns have different heights, and how they differ in relation to each other. When I align the views with each other, the alignment is done in the middle of the object, not at the bottom. Is there a way to choose what lines of the view must align with each other? Or a way to align the views to a line (for example in a sketch)?

Any way to create a parametric Parts List containing subassemblies, where the subs are listed, by name/item number, in colum format, and qty's are tabulated accross rows. (see attached as an example). If the same part number occurs in multiple subs, the part is only listed once, but the quantity for each sub would be noted. The pdf attached had to be done manually, which somewhat defeats the purpose of having software like Inventor.

I have two user parameters saved in a part template that are tied to the part volume and an overall estimated part weight. The user parameter Pc_Volume is the volume in cubic feet and calculated by pulling the part mass (in cubic inches) and converting to cubic feet via ilogic rule. This is then automatically run via event triggers before a file is saved and if the part geometry has changed to keep the volume up to date. These are exported because they get pulled into iproperties of our drawing files as well as used to create a parts lists showing the volumes and weights.
I have the property formats of the user parameters set to Number and to unitless and the unit display turned off so it does not show on the parts list, with a precision of 0.000 for Pc_Volume. The Pc_Weight is set the same way however with a precision rounded to the nearest whole number.
These are created this way so when we use the part file as the template when we select "Make Components" to separate our parts and tie them to an assembly all the files are then updated and the information saved for exporting.
The problem is, the Pc_Volume always comes in rounded to a whole number. The Pc_Weight Does as well, but that doesn't bother me since we want it to do that anyway. If I would go into the part file after it's created, double check the precision and then re-run the rule the volume will show up with the correct precision in the exported parameters. I don't want to have to open each partfile however to get this to update.
Attached are images of the parameters, ilogic rule, and exported results.

I have 2 assemblies and drawings of those assemblies. in both the same part is among the parts.
I want to change the name of the part that is in both assemblies with the Design Assistant, but i am afraid that if i will choose one of them and change the part file's name, the other assembly will be damaged. is it true?
I think this might happen because when i open only the part in Design Assistant, it doesn't let me change it's name, so, Design Assistant might not know where this part is inserted in.

When I open up multiple assemblies at the same time Inventor cant find some of the part files, even though they are on my system. Many times if the part is in an assembly more than once, some of the instances will be there and only one or two instances will be "unresolved", of the exact same part. I can open each assembly one at a time and it will be fine, but that can be time assuming. I wasn’t able to find any other threads with a similar problem.
