AutoCAD Inventor :: Parametric Assembly - Control Size Of Components And Patterns
Jan 28, 2013
I am currently working on a parametric assembly using i Logic to control the size of the components as well as patterns. However, I have hit a road block in trying to figure out how to write a rule for resizing the last roof sheet in this assembly pictured below to be even with the frame. The rule below is what controls the roof sheet pattern based on the frame length. The problem I am continually running into is how do you modify a part which is in an element within the pattern without having it affect the rest of the parts in the pattern since they all refer to part. I can get since it is hard to find information on i Logic.
Roof_Pattern_Spacing = Roof_Sheet_Width
Roof_Pattern_Count=Ceil(Parameter("Length")/Parameter("Sheet Metal Roof Section:1", "Roof_Sheet_Width"))
(Note: The red line symbolizes where I would like to have the roof sheet end.)
How to set up a dynamic block so I can control the size of an object through parametric dimensions that are linked (somehow) to a lookup table, spreadsheet, list, etc.?
What I'm trying to do (simplified) is place a block of a rectangle, select a size from a dropdown list, and have the block change to be that size - but I don't want to do this through visibility states as there are hundreds of sizes. The whole point is to be able to construct a list, lookup table, excel sheet, etc and link it to parametric dimensions in the block, or at least be able to link a stretch action to parametric dimensions. But the block editor will not allow me to associate a stretch action with a parametric dimension (at least I haven't figured out how to do this.)
find out a way to make some sort of parametric assembly.
Where I work, we make conveyors and those conveyors need legs. Those legs are all built the same except for the height and width. They are made of 2 tubes with a cross shaft between them + bolts, washer, plastic end cap.Is it possible to create some sort of iassembly or ipart for this? When creating a conveyor I would like to choose the height and width of those legs when I import them into the assembly.
Coming from a background of ProE, Usually a mirrored group of constrained parts would mirror with alternative constraints locking them in place. Is there a way to do this in Inventor?
Every time I mirror constrained parts through a Datum plane, the results are loose components that could be dragged anywhere. I might aswell have just placed them again, though it gives me a good idea of where they should be.
Without grounding them, is there someway of locking these compents in the mirrored position.
Also, bolted connections pick up on patterned holes and populate them, yet there is only one constraint to the original hole and the rest can rotate around it.
I have created a parametric, multibody master part file to derive parts from it, and then put them in an assembly. See attached file. Now, I need 3 different versions of this setup (with different values of the parameter 'bending_angle').
What is the best way to do it? If I derive parts from it, they always follow the *actual* status of their master file. Is there some method to do this: "derive from this file, with parameter bending_angle=55deg", but keep the dependency relation, i.e. if I modify something on the master file, the derived part fill follow the modifications (with the value of bending_angle=55deg)
Is there any way to group assembly components?I'm aiming at a live mass calculation for different level of details/design views.In this case I'v got an assembly with about a ton of stainless steel spread out on different subassemblies.
I have made representations showing only the welded stainless steel and I would like the weight of these to appear in the partlist. Not the weight of the complete subassemblies.
I am working on a large plant piping project and while I've seen this behavior before I've never seen it this bad.
Attached is a screen shot of a small portion of the assembly drawing in which you can see a good example of what I'm dealing with.
At the top you can see a weld neck flange that appears to be attached to air where there should be an elbow. In the middle you can see that on one side of the elbow there is missing geometry.
At the bottom is another flange that attached to air where there should be an elbow. This drawing is littered with these errors and as such is unsuitable for even a reference document.
I have turned visibility of these components off and on without resolution. I have turned on tangent and interference edges without resolution.
I have translated a copy to ACAD to see if it's simply graphical but the ACAD file shows the same errors. I have checked parallel and perpendicularity and all is well.

I'm running Inventor 2008 SP2. Each time I open the assembly 2 subassemblies always explode. You can see the red and blue subs in the attached picture. I thought this was supposed to be fixed by now. Actually I thought this was supposed to be fixed in R11 a long time ago. When I grab and drag either component, everything snaps back to where it's supposed to be.
If this isn't fixed (along with a laundry list of stuff that's been broken since R10) you will be losing customers. This and all the other bugs have cost me countless hours in lost productivity.
In Inventor 2012 I know that it is possible to arrange assembly components in a circular or rectangular pattern. But is there a way to arrange these components in an oval pattern?
I need to modify all the ipt in an assembly, but I don't kow how many ipt I have, and I don't know the name. Can I have with iLogic the list of all the ipt used in the assembly ? For example, to modify the Part Number in all the components.
Here is the history. I originally created a part with multiple solid bodies.
After creating it I was told we needed to make it an assembly. So what I did instead of recreating each component I called up the original multi-bodied part and did save as copies.
Then deleted the portions of the model I didn't need with only the part needed left.
Then I took all of those parts and assembled them together to form an assembly.
Now, here inlies the problem. When I go to make a drawin gof this assembly all of the balloons are coming up with the same item number as it was when it was a multi-bodied part.
It is clearly an assembly based on the model tree and the file extension.
I have a machine assembly with old part naming. Now we have a new part naming system. So i am supposed to rename all existing parts, assemblies to new naming system.
E.g. : A machine assembly with old names (lets say part1, part2..... part1000). It has to be renamed to new names (say item1, item2.....item1000).
"part1" should be renamed as "item1" and so on.
Design assistant is not a good option because its a lot of manual work, its same issue with using Vault.
Currently I have some code which loops through all sub components of an assembly and sub assemblies. However I only need sub components inside the top level assembly and not any sub-assemblies. Is there an easy way to acomplish this?
This code will list all sub components inside an assembly when a drawing is open.
Dim oDocument As Document Set oDocument = ThisApplication.ActiveDocument Dim oRefDocs As DocumentsEnumerator Set oRefDocs = oDocument.AllReferencedDocuments Dim oRefDoc As Document For Each oRefDoc In oRefDocs debug.print oRefDoc.FullDocumentName Next
It seems to me that the basic exclude component no longer works when deriving assemblies. If I cycle through components it is not possible to get the Grey circle with the backslash through it?
I'm a playground designer and we're currently in the process of updating our systems to Inventor. Over the next few years I'm going to be working on many different assemblies all using the same parts and sub assemblies, many of which need to share the same ground plane.
I'm wondering if there is any easy/quick way to make certain parts (not all) automatically constrain/flush to the ground/XZ plane when I place them?
I want to create numerous custom properties for a part. Some of these will be the same for all instances of the part (i.e. vendor, part number, etc). But some have to vary from instance to instance.
So, as an example - if I place 5 identical tanks into my assembly I need to assign unique text entries for each of these 5 instances (i.e. TANK-01, TANK-02, TANK-03, etc)
Furthermore, all these textual properties have to be able to be shown physically on the part (for identification on plots) and extractable for BOMs, etc. It seems that any custom i Properties I set up are global for all instances of the part.
Long time Autocad user but now am moving most of my work across to Autodesk Inventor.
Some of the work I do is with companies that their parts are standard components that will not change.
So I am using Inventor to automate the drawings based on their requirements. For example if it needs to be 4m high. then to use 2 x 2m sections. Currently I have create different assemblies of the different potential heights that I can switch between using ilogic but I need to be able to shift the top truss arch depending on how high the truss is.
I have an i assembly with some lengthy and unique ilogic to control what parts are included / excluded based on user inputs in a form. To begin, the program includes all components, and then excludes the ones that aren't needed. This is basically, briefly what the first part of that looks like:
For Each oCompOcc In oCompDef.Occurrences i=i+1 'Include all currently excluded components If oCompOcc.Excluded=True Then oAssObj=oCompDef.Occurrences.Item(i) oDoc.SelectSet.Select(oAssObj) ThisApplication.CommandManager.ControlDefinitions.Item("ExcludeCtxCmd").Execute()InventorVb.DocumentUpdate() Else End If Next InventorVb.DocumentUpdate()
So this works just fine, mostly. I run into an issue with the component occurrences that are within patterns (I have 2 patterns - 1 circular and 1 rectangular). This code will "Include" all occurrences inside an "Excluded" pattern, but the pattern itself remains "Excluded". In other words, in the browser, the pattern name appears greyed out and crossed out, but all the elements and the components within them appear "alive", so to speak. But the BOM indicates a Qty. of ZERO for these components since the pattern that.
I can toggle include / exclude of patterns using the same method:
I was just wondering how to place a component into an assembly using ilogic? If this is possible, is there also an option to choose if iMates will be generated?
I would ideally like to place a list of components into an assembly, the list with probably exist in excel, then have iMates set to 'Automatically generate iMates on place' so that my assembly assembles automatically.

Assembly comprised of multiple components all derived from the same master sketch "4 Inch Rail Master Sketch"
Using the sketch to drive geometry, using the parameters to drive various extrude lengths.
Geometry changes seem to propogate quite well, while parameter changes do not...is this a bug or am I doing something wrong? Generally have to open each individual part and "edit derived part" to force changes to propgate...
files attached (move end of part marker down for all .ipts).
I have a part with a rule 'PlaatsPaneelNummer " which I place text on my part. Now I have that part in an assy posted regarding the use of a placeholder.
Now I want the rule 'PlaatsPaneelNummer' drive from the assy. I keep getting the message that the sketch in which the text is placed can not find. I can not manage to show this in the rule.
I am trying to control the parameters contained in a part that is not in my assembly. May sound odd, but I am using the multi body part modeling feature to create all of my bodies in a single part file, then making these components/sub assemblies, and pulling them into my assembly. However, I do not want to have the "control part" in my assembly, I just want it to drive the parts. I cannot figure out how to access these parameters without having the part included in the assembly...
Im having problems to control the slope patterns. This is especially visible i corners where the slope patterns distance is very small. I have tried to fix this in the edit slope pattern put i cant get it right. I would like to have my slope pattern every 5 meters. This cant be to hard to fix, right?
i want to control the scales of my idw views based on the parts size.
Heres a short intro to what we do, using design assistant we copy an existing project to a new project folder and start designing using the old project as a "template" for the new job.
So, lets say the project i just copied has a part that is 100" "tall", on my drawing sheet the view scale is set to .05 and the view fits nicely on our 8 1/2x11 portrait layout.
Now, the new project's part is only 24" "tall" and using a scale of .05 is no good at all, i need to scale the view up so it will fit nicely in the same layout. This also applies to the associated detail and section views that are on the same sheet.
OK then, Im thinking there should be a way to say if dimx is >=100 then view scale is x and so on if the part is smaller and i would like to do this with the details/sections.
As the pics show, when i change to a smaller size/dia, the views scale needs to be increased. How can this be done... (we do not use vault)
Where is the setting to control the size of dims in the IPT sketch environment. The arrow sizes are OK, but the dims are so small they are unreadable to the point of having to double click on the dim to get the actual value.
