AutoCAD Inventor :: Automated Assembly Based On Work Geometry
Aug 13, 2013
I'm trying to setup an assembly based on a complex 3D sketch. In simplest terms, if I have a sketch for the perimeter of a house, I'd like to add instances of a 2x4.ipt at specified locations automatically. That's not necessarily every 16", but rather wherever I put a specific geometry. I'm imagining two work axis or sketch lines, one along the perimeter to determine the location of the 2x4 and one perpendicular to determine the direction the 2x4 points.
In actuality my sketch won't be a rectangle, but rather a complex 3D spline, that's why I'm hoping to get some sort of automated process. And the current design involves somewhere on the order of 1500-1800 2x4s. Making the sketches and geometry will be nightmarish enough, I'd prefer to be able to breeze through the assembly portion.

I am trying to generate automated drawing for my assembly and iam trying to run the following code
Imports Inventor.ViewOrientationTypeEnum
Imports Inventor.DrawingViewStyleEnum
dim oDrawingDoc as DrawingDocument
dim oPartDoc as Document
dim oSheet as sheet
dim oTG as TransientGeometry
dim oView1 as DrawingView
[code]....
but when i run the code its asks me whether you want to generate the drawings, but when i say yes shows runtime argument error as show below
Error in rule: Rule0, in document: pin
The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
when i ask for more info it shows the following error
System.ArgumentException: The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

I created the following user parameters:
-Thickness
-Width
-Length
-Dia
I then created a Custom iProperty which consisted of the following "formula": Finished Material Size = <Thickness> x <Width> x <Length> Lg.
eg. of Finished Material Result : Finished Material Size = 6 x 25 x 300 Lg.
The problem comes up when dealing with diametrical components as the above formula will only populate for square or rectangular parts. Which would work if I could use iLogic code to populate the Finished Material Size iProperty. I have tried but failed.
First I created another user parameter called "Geometry Type" which has a drop down selection of either "DIA" or "SQUARE, RECTANGULAR".I then created the following iLogic code to set 0 as the value for the "unused" size parameters
If PART_GEOMETRY = "DIA" Then WIDTH = "0"If PART_GEOMETRY = "DIA" Then THICKNESS = "0"If PART_GEOMETRY = "SQUARE, RECTANGULAR" Then DIA = "0"
The part I just can't get to work is as follows.
I need some iLogic code which will populate the "FINISHED MATERIAL SIZE" custom iproperty with one of the following based on my "GEOMETRY TYPE" selection. "DIA" would return the following to "FINISHED MATERIAL SIZE": = Ø <Dia> x <Length> Lg.
While "SQUARE, RECTANGULAR" would return the following to "FINISHED MATERIAL SIZE": = <THICKNESS> x <WIDTH> x <LENGTH> Lg.I tried the following code but it does not work:
If PART_GEOMETRY = "DIA" Then iProperties.Value("Custom", "FINISHED MATERIAL SIZE")= "Ø"DIA "x" LENGTH "Lg."If PART_GEOMETRY = "SQUARE, RECTANGULAR" Then iProperties.Value("Custom", "FINISHED MATERIAL SIZE")= THICKNESS "x" WIDTH "x" LENGTH "Lg."

We have some serious problems by creating assembly drawings with reference geometries in inventor 2010. Our target is, to create a drawing that look the way, the attachment shows (Picture-1) The sheet metal plates Pos 10-100 are an assembly. And the assembly in the back is the reference geometry. It’s a frame consists of steel sections. What we want: 1. The frame must be phantom lined in the idw. 2.
The Sheet Metal parts must be thick lined. 3. The Partslist of the Assembly should only contain the sheet metal parts and not the frame We have some ideas to solve this case, but each of them is nor perfect (please see the attachment Box.pdf) And there’s another problem (described in part 3 of attachment), we cannot position viewports or drawing elements to each other exactly. You have no possibility to give them dependencies. Also if you want to position symbols to each other. All of them are only near to be exact, but that’s a big problem. If you change contents of a viewport, another should be aligned to it, but that doesn’t work.

I have an assembly with a few parts inside and want to create a new part(hose) in the assembly and link some faces from other parts within the assembly to my new part to show the routing of the hose.
Can I link faces within an assembly to one of the assembly components.

I have geometry not updating after replacing a component in an assembly.
I have drawn part A and in the assembly environment I have projected cut edges on a XY Plane in a 2D Sketch.
After replacing component A in the assembly with part B (not identical but very close) i was expecting the projected geometry to update. But it doesn't. The "local update" button is greyed out in assembly mode. also the Rebuild command does not seem to update the projected geometry.
I can see the new 3d shape and the old projected geometry. How to get the projected geometry to update?

On one part, I have a bore hole drilled on a curved surface so the hole is actually an ellipse.
Now the other part I am trying to constrain together is the pipe that will be welded into the bore hole; so that is a simple circular pipe.
The issue is that the pipe has to be inserted 0.25" above the interior of the bore hole to allow for room for the weld. In order to do this I have tried to create a plane attached to the 3D ellipse and then constrain the pipe to be 0.25" above that plane. The problem is I cannot seem to create a plane attached to the 3D geometry; I cant even find a way to attach points, or pick the center point of the bore hole.
How to create a plane on 3D geometry and link it to said geometry. I'm using 2012, if that is necessary information.

In the attached part if I change the value of the length parameter from 19" to 20" Work Axis 1 updates to the 19" location, if I change it back from 20" to 19" it goes to the 20" position.
In the images below, the axis should be in the center of that last slot.

Inventor 2012.how would I input the total quantity of doors in the .iam in order to update the Parts List quantity column? I have a lot of user inputs in the .iam file set up to change width, height, etc that are based off of Parameters in the .iam, but I don't know how the user can enter assembly quantities in order to get the Parts List to update the Quantity column correctly?
I have attempted using custom iProperties but how to get it to display based off a user input Parameter.

I have an ipart that will has the length and a quantity of patterned features controlled by a table. I've created a work plane that I'll be using when I take this part into an iassembly. The problem is that the features I used to create this work plane (midplane between two parallel planes) do not exist in (2) of the (3) members...so it gives me an error message. I've tried adding the work plane to the table, but 'exclude' isn't a drop-down (and typing it in doesn't work). How to make the work plane "inactive" for those particular members?

I have an assembly that was generated by Pro/E. It opens fine, but there are roughly 1000+ planes that are all visible. Is there a way to easily shut these all off whithout having to do it in each part?

I have a linear slide assembly, for which I've set up limit constraints in the open and closed position.
It all works well, with one being able to drag the slide open and closed and the parts stopping in the correct positions.
I then inserted 4 of these assemblies as sub assemblies in a parent assembly.
I then constrain another part to the 4 slides.
I want to just drag on this part, to make the slides move to open positions.
This is to check kinematics etc.
One cant do this. You can only drag one slide open, by activating that slide in the model browser.
Any way to make limits work properly in upper assemblies?

I have a formed beam I would like to mirror in an assembly to avoid the work of forming the opposite bent part. I have mirrored it however the cuts in the lower side of the beam are mislocated as if the part were rolled over rather than mirrored.I am in Inventor 2012.

There are two cases, that should behave the same, but they don't.
First program works normally. Inventor generates a circular Pattern with the given Part.
' Part referenced in Obejct-Collection-Object
o_ObjectCollection (is defined)
' reference an Axis of the Assembly
[Code].....
Now, the second case, I try to take the Work Axis from a Part, that is placed in the Assembly,
but Inventor does not generate the Pattern. If I set the Axis visible, or even rename it, it works. But the AddCircularPattern does not work.
' Part referenced in Obejct-Collection-Object
o_ObjectCollection (is defined)
' reference an Axis from Part, placed in Assembly
[code]....

I have one large assembly for hose routing it consists of around 1000 hoses all hoses are coming in main assembly but delivery date is very short. My plan is work on same assembly 5 people how it works?
One idea is like working in sub assemblies but in my case only one assembly consist of all hoses.
How to work multiple users in single assembly file at same time. like in solid works enable collabarative mode.

I have an assembly that is a general model with different modules that all are iAssemblies.
With this model I can speed up the design process at the company I am working for.
In the model I only choose the correct member for the iAssemblies and the assembly updates correctly and just with a couple of clicks I have made a configuration of all the modules.
Now, I would like to take it a step further and have the drawing, for the specific configuration, generated automatically.
In the drawing I would like to have the master assembly presented in sheet 1 and the modules presented separately in different sheets, all sheets with BOM lists.
Is this possible to do?
(Next step is to export all the BOM lists to an excel document that can be sent to the product co-ordinator to build up the database system)

I am mechanical drawing and search a better way for the drawing generation. I have to learn some of VBA (or VBS?) for use Ilogic rules. My questions are:
1.- How learn or search more easily and faster the inventor objects for drawings and how to use this objects, undestanding the relationship between its function names and another properties for writing the correct mode in VB? I know some of VB buti see that the library objects from Inventor are "a lot of stuff".
2.- Is there a rule that can get, automatically, the centerlines from a drawing, when the drawings is generated in a idw file? (10 drawing in one idw file ).

creating a named sketch block (in an ipt) containing entities that I have created in the same sub? I'm doing this from Excel, in Inventor 2010.
What I have:
Function CreateUncutTagSketchBlock()Dim IVApp As Inventor.ApplicationDim oDoc As DocumentDim oCompDef As ComponentDefinitionDim oSketch As SketchDim oTG As TransientGeometryDim FileName As StringDim Coords(1 To 10) As Point2dDim oSketchCircle As Circle2dDim oSketchArcs(1 To 2)
[code]....
note that i've also taken a shortcut with the arcs, and the circle. I did try to create them using the same naming convention as the lines, but... I failed to implement it successfully.Also, I can not quite figure out how to constrain all the start/end points together.

Is there a reason a sheet metal "cut" isn't an option for the automated centerlines tool? Am I overlooking something? When I make holes in sheet metal parts, I draw the circle then "cut" it into the sheet metal. For some reason I can't find how to give those automatic centerlines on drawings.

When I click to to automated centerlines, it usually places a vertical/hozional centerline on all the circles in the drawing like in the first attachment. But, sometimes it will make the centerline to angle around the center like in the second attachement.
What you have to do so that the centerline come off at angles like in the second picture?
Otherwise I end up using the centerline feature and drawing them all in which is a real hassel!

I'm attempting to create a model that autmotaically derives ready-to-go drawings. I've gotten pretty far in doing so but have a few issues with regards to dimensioning. As I'm sure you're aware, when the model changes, a dimension to that feature, which has been removed, is also deleted and some those dimensions do not return once the model is changed back.
I have looked into using different view representations, but have found that they do not accommodate feature supression.
Is there a way to program in the dimensioning of a view.
Create center points for of the holes and center lines.
And for a feature note such as "Hole and Thread" dimensioning, when the model expands, the leader and text length do not change and proceed into the view. Is there a way to fix or anchor the text to a certain spot on the drawing, and have the leader length expand and change accordingly to that point.

I am using Civil3D 2011 and have a need to create an assembly that will take one of three options, depending on the tie-in condition points (e.g., the end of a link, not the beginning). As far as I can tell, Civil3D can discriminate which sub-assembly to choose based on conditions at the link starting point (e.g., if the start point is 2' of fill, it will select sub-assembly A; if the start point is 2' of cut, it will use sub-assembly B, etc.). However, I have a condition where the cut/fill conditions at the assembly start point have little to do with what I want the subsequen sub-assembly to do.
For simplicity's sake, you can imagine my "existing conditions" (2D) section as a flat-bottomed, U-shape with vertical sides (i.e., a trench); it's bottom width can vary.For the time-being, let us consider one side of an assembly in a fill condition only. Imagine that I want to satisfy design constraints but limiting fill quantities is a second priority; in instances when the bottom width is small, I would want the assembly to catch the existing trench with a 2:1 sideslope fill (or in Civil3D speak, a cut, because it would be upwards), so my finished surface is a now a V with the vertical faces above it. That works fine and dandy for a "trench" a few feet wide; however, imagine if that trench were 100s of feet wide - a 2:1 side slope would be a lot of fill for a ditch. So rather, I would want to "embank" the ditch - 2:1 side slope up (cut) to define my ditch XS, a horizontal link over to "embank" it, and then a 2:1 side slope down (fill) to catch the flat-bottom of my trench. So as you see, both situations have the same "Cut/Fill" condition (starting point) but drastically different end results.

I'm currently trying to make an automated fence generator with Inventor 2012 driven by iLogic rules.
My model is done now, and my BOM information (description & part number) is set correctly.
Now is my problem some parts are not supposed to be in the BOM at a certain moment.
Example.
If fence_type = 1 Then
Beam-001 = default
Else If fence_type = 2 Then
Beam-001 = reference
Else If fence_type = 3 Then
Beam-001 = reference
End If
But what do write to set BOM status of a part?

pdf drawings are king at our company. When we creat a product, pdfs (and sometimes stp files) are generated and placed in folders organized numerically by part number.
Our challenge is that finding all the current pdfs for an assembly is not automated. Thus, to get all the current drawing pdfs, someone has to open up the top level pdf, read all the part numbers, go get/print the pdfs of the parts, subassemblies, subassembly parts, etc. This is time consuming and error prone and getting worse as the number of parts we always increasing.
I'd like to automate the process. I'm thinking about a program/script that: Extract parts list from pdf of Inventor assembly drawingCopy pdf of individual parts/subassemblies to a directoryMerge all pdf for that assembly into single pdf.
