AutoCAD Inventor :: Multiple Components In Assembly - Derived Part Not Updating?
Jun 14, 2013
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).
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 have a part (several actually) that I made using the mirror command. I made these in 2012. When I converted to 2013 and set up my new appearance freindly materials, I changed the appearance for my 201 S/S matl to "Stainless Brushed". The first image is of the derived part which is stuck on a "Steel" appearance, the second image is of the base model which is correctly displaying the "Stainless Brushed" appearance. I tried playing around with the appearance overrides and I can't seem to get it to update. My assembly looks like **** with the different appearances.
For chuckles sake I'll also mention that every time "appearance" appears in the above paragraph I typed color first and corrected it.
I have a vba project that can extract an assembly BOM.
However, it does not output derived parts. What is wrong with my code, shown in the attached file?
What I am trying to do is create a ipt file of a "Laser-Cut" component. Use this component to make another component with drilled, tapped holes in it. Then use this plate, containing the drilled and tapped holes in an assembly.
I need to output this "Laser-Cut" part in my vba created BOM. Is it possible?
I am trying to unfold a part created from a derived assembly like I usually do… why in the world will it not unfold, and show a preview of the unfolded in the other direction??
At first all was working… until I added a part (see the circled item in picture), and I don’t have any problem usually!
My issue is we have Universal assemblies that never change. These assemblies are thousands of parts. (hardware gaskets other random assemblies.) this top level universal assembly never changes.
to increase time in layouts. we would like to create these universal assemblies into 1 sold part.
Is there a was to export an assembly into a single solid part.
I've got a machine designed that has a couple hundred parts - originally built as one main assembly (with a number of weldment subassmblies). The problem is that the BOM is too large to feasibly have on the drawing and still show assembly detail. I'm trying to avoid a multi-sheet configuration.
So I've grouped certain items and demoted into subassemblies. The problem is that all the subassemblies are attached to a main frame- and I'd like to show this frame in each of the subassemblies as a reference. Is there a way to add a "phantom" copy of the framework to each of the subassemblies to that it can be seen? (and the assembler can see how the subassembly is mounted on the frame) Otherwise all these parts are just floating in space on the subassembly (and constraints are lost on the subs).
I'd like to keep the frame on the top assembly, as it may be customized for future machines, while using the same subassemblies.
Does frame generator update placed components when the profile of a custom structural shape family changes?
Workflow:
1. Create custom family in Frame Generator library.
2. Place instances in a frame generated assembly.
3. Make a profile change to the base shape and update the library using "Replace Family Template"
4. Open assembly with placed components and select Design > Frame > Refresh.
The profiles of already placed components do not update. Existing parts are unchanged even though any new parts placed from the family receive the new profile.
Under our previous workflow using derived parts, we created sketch files and saved them in a profile folder. Then all lineal lengths derived their base sketch from those profile .ipt files. When the sketch changed in the base .ipt, all the files derived from it updated. I am trying to replicate / improve this workflow using Frame Generator, but it doesn't seem to work.
Am I doing something incorrectly? Or does Frame Generator not support automatically updating existing frames when the profile of the family template changes?

We have written an add-in that allows you to specify position and non-uniform scaling while creating a derived part.
[URL]
Some potential uses of this add-in include:
1.. To simulate an iFeature where you add or remove material - use Sculpt to add and Split to remove material. Unlike iFeature you could edit the source and make the changes be reflected in the derived part.
2.. To simulate an iFeature that places a sketch - useful for designing frames.
3.. To design a progressive die - you might want to place, with relative displacements, multiple parts representing different stages (or configurations) of a formed sheet metal part
4.. To realign (rotate) a part - sometimes skeletally driven parts (for example, four-bar linkage members) are not aligned with their "natural" coordinate system, causing skewed drawing views
5.. To derive a part with different scaling factors in X, Y and Z directions, which is useful in mold design
6.. To integrate two skeleton systems that do not share the same coordinate system
7.. To create scaled sketches (this should become useable after R11 SP1)
It says i can exclude parts from the assembly, when i insert it as a derived part, but the exclude button is greyed in the insert derived part dialog box.
I can't find a way to create multi flat patters in one part from a lofted sheetmetal part. Also, didn't the developers fix the 'can't make a flat pattern from a derived part'?

I´m trying to measure the base dimensions of simple geometric shapes. I started out with plates since they are easy to measure as long as they sit in 90°, 180° and 270° positions relative to the origin. Then Measure.ExtentsLength, Measure.ExtentsWidth and Measure.ExtentsHeight will give me the base dimensions of a plate.
However, if the plate sits abitrary relative to origin this will obviously fail, since Measure.Extents only measures in x,y,z
Is there any way how I get positions of the geometry that is in the part, like corners surfaces on the B-REP so I can calculate the dimensions properly for a plate. I´m not sure if this is possible with iLogic. I have a strong suspicion VB.net would be needed for this.
Another problem I have is that derived parts don´t get triggered to run a script when I change the geometry in the Multibody Part and the rule is set to run by any modelgeometry change.
I got this code earlier from Curtis_Waguespack, and i would like to add a setting... When i run this rule it Derives the assembly, but LOD is set to Master, i would like it to be set to my own (Configurator) LOD...
I don't seem to be able to find anything in this code, that defines LOD...
So far im doing ok with the standard ilogic code, but when it´s API or VBA code im lost.. which leads me to this.. i've been searching the forum back and forth to find a code that performs the feature "Shrinkwrap", and somehow everything i have found so far does not work... even the code example in Inventors help menu under programming, Therefore im trying to solve this with Curtis's code as staring point..
'set a reference to the assembly component definintion.'this assumes an assembly document is open.Dim oAsmCompDef As AssemblyComponentDefinitionoAsmCompDef = ThisApplication.ActiveDocument.ComponentDefinition 'define the path and file nameDim sPathandName As StringsPathandName = ThisDoc.PathAndFileName(False)
it's possible to create a derived part using only some of the features of the base components i.e. I've got a funny shaped part with a bunch of holes in it, and I need another part with exactly the same shape but totally different holes (location and size)I know you can do this with the different solids in the part (only use some of the solids) but I haven't been able to figure it out with features, if it's possible at all.
I could probably create one base part (just the shape) and derive both parts from that, but then I've got a part lying around doing jack.using IV 11.
I have created a very simple yet effective tool for starting a new manifold assembly using iLogic. The rules and windows essentially fill out the size of the block, material type, description, project and part number.
Below I have a hydraulic manifold I have designed and from that I created the final .ipt of the internals. The way I did this (which may not be the best method) was to create a second .ipt matching the LxWxH of the original manifold, next I inserted and aligned both into another .iam file, lastly I derived a third .ipt from a subtraction resulting in the third image below. This is a bit time consuming to create, but has been very useful in error checking our designs. I would like to see if iLogic is capable of allowing me to automate this so we can easily create these internal flowpath .ipt's for every manifold we design.
Is it possible to change the derived part link to another part like you would replace a component in an assembly? My issue is that i created a part and used a derived part within. Well this part number changed and it just so happens that the derived part needs to change as well. I tried the design assistant, and changed the link there but it didnt seem to want to take. I tried renaming the derived part, and opening the file...i get the error but i still am unable to change the link that way either.
I am having some trouble with this quick VBA app, I want a utility that can traverse all the parts in a top level assembly and suppress the link to each derived part (multiple) in all the parts in the assembly.
I have played with the following
Public Sub SuppressLink() Dim partdoc As PartDocument Set partdoc = ThisApplication.ActiveDocument partdoc.ComponentDefinition.ReferenceComponents.DerivedPartComponents.Item(1).SuppressLinkToFile = True End Sub
Which works, but only on one part file, and only on the first derived part. Is there any easy way to make this work on ALL the dervived links and every single part inside an assembly?
We do a good bit of deriving parts from assemblies. We have a workflow that works well for us, we create PARTS, put them in an ASSEMBLY, then create new PARTS DERIVED from ASSEMBLY. We use Boolean to add/subtract and disregard parts as needed to create these parts. These parts are now given color and reassembled in an yet another final ASSEMBLY as needed and put into a drawing.
Through Inventor 2011 this worked well.
In Inventor 2012 the color is disapering as soon as any change is made on a source part.
1 Changing the color does not work.
2 In the derived from Assembly, opening up (in the browser) the individual .ipt's and right clicking and clicking properties and changing the color only stays until the next change to the source prt.
3 Changing EACH individual face by right click, properties and setting the FACE PROPERTIES from "as feature" to "as part" does work, but is ridiculous to change hundreds of faces on each part. (especially considering we did NOT need this step in 2011)
Is there a switch in the registry (to turn off the standard “as feature” to the parts face).
I have several iParts with their respective derived parts in my library. There are not many other Inventor users here that use those parts, but they might benefit from having those individual parts. The iPart may change from time to time, and in order to keep the individual parts current, I am required to activate them one by one, exporting them to STEP, IGES, SAT or IPT files for both people here to use as well as our Pro-E and Solidworks users. Is there a way to automate that process so I can hit a button and have it save all instances to a certain file format?
I am trying to patch up a bunch of small holes in a derived assembly. I've tried going to the options tab that comes up when deriving the part/assembly and plugging in values for the range of hole sizes to be patched, but I get no results when clicking ok. I have scaled down the assembly to 1/10 the original size. I set the range of holes to be patched from 0 to 0.25". The diameter of the holes in the assembly are only 0.017" after scaling down.
