AutoCAD Inventor :: Array / Pattern Features With Different Dimensions For Each Instance
Sep 19, 2012
I would like to generate a rectangular pattern of extruded tubes which have an internal radius that is proportional to the distance to the centre point of the pattern. Or in other words tubes which are narrower in the centre, and wider at the exterior. Is there a way to do this without resorting to creating each tube individually?
More generally, is there a way to parameterise a feature dimension/parameter so that it is a function of spatial position?

As you see in the template photo (the photo was scanned by Microsoft Security Essentials, healthy) I wanted to extrude my circle, and I made 28 pieces with circular pattern feature; now, do I have to choose all the pieces by one by to be able to choose all?
The sum of the problem: while using the Circular Pattern feature or rectangular pattern feature in Inventor, sometimes I want to extrude (join) or cut the drawings that I made (augmented) with using circular pattern feature, rectangular pattern feature. in this case do I have to choose all the augmented members one by one (for instance I make 42 augmented members), it can take a lot of time.?

My flat pattern of a sheet metal part fails when I added strenthening Press ribs to the middle of the part using an iFeature.
I know Inventor is not capable of flattening embossed sheetmetal but is there a way to still get the flat pattern & ignore the formed areas?
Seems to me I was able to add some model features in the past like bosses, extruded holes KO's etc & I could still make a flat pattern.
I know I can use derived part to do it but that adds complications.

Is there a way to "skip" features i'm creating a pattern by?Meaning, similar to this option in Proe and Solidworks, is it possible to choose some of the holes i'm copying, so they won't be created?

I'd like to add a dimension from a feature in a detail view to a feature outside the view, exactly like the dimension circled in red below. I cannot find any information on how to do this, but I suspect it is pretty easy!

I have entered in all the available sizes and have the outer frame of the louver adjusting nicely.Now where I am running into trouble is setting up the louvers and the louver spacing. I have been playing around with the parameters for awhile now and I just can't wrap my head around some things.
Example one:
in the picture below,
HEIGHT is selected on 18 in
I have created an user parameter called LOUVER_QTY which is set to subtract 1.6 in off HEIGHT = 16.4, then I divide that by 2.05 and the result is supposed to equal 8 but it is showing 3.149606. But when I assign LOUVER = LOUVER_QTY it is showing 8
For the most part this file works fine, but when the Height is changed to 56 in, the last bottom louver runs through the bottom of the frame.
I know that I have to change the spacing from a direct input (2.05) to a equation based on height to fix the spacing, but I can't grasp how these parameters are working, why are they red(errors)
Also I don't know how to set up the parameters to set the correct number of occurrences in the rectangular pattern to control the amount of louvers. Something related to to the spacing of the pattern and the selected height.

Let's say that I'm making a simple L bracket. I'm going to form it, and machine the holes in both ends *after* forming. So I don't want the holes to show in my flat pattern.
On the few threads I found, the consensus seemed to be that you may have to have the part file contain no holes and put them in as assembly. So I just accepted this that it must not be able to be done.
Then I ran across a piece of promo literature online from AutoDesk that made mention of the ability to create "postform" features that obviously are created after the forming process.

Is there a feature on the latest series of inventor whereby you can automatically generate fold detail on the flat pattern , ie. fold up 45 degrees, eliminating mistakes. I am currently on Inventor 2008 so this feature could be on a new version.

Sometimes when I drag a new symbol instance to my artboard and resize it, the instance looses it alignement with the pixel grid.
This happens despite the fact that...
I checked the box for pixel grid alignement when I created the documentthe symbol option is set for align to pixel gridthe original shape in the symbol is aligned to pixel grindthe original shape has the align to pixel grid check box in the transform panel checked
So why when I resize the symbol instance does it break the pixel grid alignmnet and result in a blurred 1px stroke?

Trying to do some bolt pattern center lines. Been doing them for years and can do them old school way. But was wondering if there is a better ways. If you put a circle from the center of the bolt circle to the center of the bolts and change it to center the hashes never line up. So I always do small center line sections on each bolt hole. Then array it around to cover the entire bolt circle. But that gets time consuming. I am now doing a lot of projects with bolt circles and wondered if there was a better method.

I just re-installed windows and all the fine (PITA!) trimmings. Now, when I open a file (any type) for Inventor thru windows explorer it opens a NEW instance of Inventor everytime! This is a HUGE system hog, waste of time ect ect.
How can I correct this to just open in the instance that is already there?

I want to create some modules for a platform deck. The modules are made of C5x6.7 channels in one direction, L2x2x3/16 angle stiffeners in the other direction, and 3/16" deck plate on top.
My "drivable" parameters will be length and width.
The modules will all be different sizes, so I need to be able to have every instance of the assembly be different.
The workflow I was attempting to do before I got stuck was this:
1. Create a skeleton part (just a sketch) with Length and Width parameters.
2. Insert in an assembly and use frame generator to build the structural shapes (channels and angles)
3. Insert another part (the 3/16" plate) that can reference the length and width and adjust to be the correct module size.
Is there a way to make parts in an assembly all follow the same parameters? More importantly, can each instance of this assembly show up differently and be adjustable when I place these modules in my main assembly?
I don't know much about iParts - but it looks like an iPart lets you choose from predefined dimensions - I want something that I can custom input any size I need.

I've been tasked to turn our 2D cad dwgs to 3D in inventor.
I'm working on a frame at the moment, I got all the square and rectangular tube from the CC and constrained them to match the CAD dwg, now I need to add the mounting holes but if I add holes to one copy all the copies get the holes.
What option can I use to make each instance stand alone?

sometimes when using constraints the "movable" part is fixed after adding the first constraint.
If i use i.e. a surface to surface constraint the movable part should be free to slide on the surface.
To move the part in this case I have to add further constraint or delete the old one.
Furthermore sometimes constraints in assemblys do not update automatically. I have to click on the part and try to move it away. After releasing the part the consraint will be updated.
Are there any options to control or better change this behavior?
I am using Inventor 2013+Vault 2013.

Whenever I attempt to open a non-native format file from outside of Inventor it launches a fresh instance of IV. Currently I've been working around it by dragging the file to the status bar of IV, but at least a few times a week I forget and double click it.
Some scouring of the web and these boards yielded some info concerning this problem as it pertains to native formats, but I haven't been able to find anything for neutral formats. I'm sure it requires a registry key tweaking, but I'm not comfortable enough with regedit to go in there and just start changing stuff without some level of guidance. The problem occurs whether the files are opened from windows or an internet browser (tried firefox and ie). I suspect that every format I ever wanted to open would require a separate edit, in that case I'd be perfectly happy with just a fix for .step files. That would at least have me set for 90% of my downloads and offer an improvement to my overall sanity level.

I typically as much as possible like to insert my dimensions into my drawing from my model.
I created holes in the model as a 1/4" tapped hole
Yet when I show the dimensions in the drawing they show the minor dimension.
How do I get the 1/4" to show? I have selected the feature and still get these results.

I'm trying to use the PATH array feature on 2013 to array stairs, and I can't get the array to be 100% accurate. It seems like CAD rounds the decimal to the nearest 3/4" which could be causing the problem.
I set my run to 10.5" and rise to 7.25", array along the angle of the stringer, and there's always a small overlap on the stairs. The "distance between" should be 1'-209/256" and CAD rounds it to 1'-3/4" which is where I believe the error is. Is there any way to fix this or array this correctly? Otherwise...back to the COPY method I suppose.

How can I make a circular pattern of a single occurence of a rectangular pattern?
A shaft has a rectangular pattern of holes (along its axis) on its surface. I want to pattern the 4th occurence of this hole pattern as a circular pattern? Can I do it in Autodesk. I can not select the a specific occurance of a patterned feature to pattern it again.

Is it possible to take a feature created by a pattern and reuse it to create another pattern? I have a circular part on which I have created a linear pattern (using the rectangular pattern feature) of holes, 6 in total listed as 3 ccurrences. if we number the holes 1-6, I would like to make a circular pattern based off holes 2 and 5. I have been unable to figure out how to select the individual "occurrence" related to the hole once in the pattern feature. If I create the circular pattern first and then the linear and try to suppress the others it supresses both holes in the occurrence.

I am creating an assembly with my base part being a weldment. I've added other components that mount to my base part. Now I need to add fasteners to the mating components. I have added my first fastener and now want to pattern the said fastener using the "Pattern Component" and by using the "Feature Pattern Select" option and selecting "Associated Feature Pattern". At this point I have already selected the component that I want to pattern and selected the "Associated Feature Pattern" to select my base pattern. The only problem is that I am unable to select the pattern desired.
A note on how my Weldment was constructed -The holes were created in the "machining" step of the weldment, not in the individual part before it was placed in the weldment assembly.
If I move the hole feature and its pattern to the individual part and then place it in the weldment assembly, I can then create an "Associated Feature Pattern" in my assembly file.Why can I NOT create the associated pattern when my hole features are created in the weldment assembly? Or am I missing something?

I have an assembly which I am using as a icopy component. In the assembly I have the adaptive sketch which os used for the icopy function and a part which is adaptive to the sketch. I then have the part pattern itself in the assembly. The problem is the pattern will not update when changes are made unless I edit the pattern. The pattern references parameters from the sketch so that when the sketch changes the pattern should change. It works but the pattern will not update unless i open the pattern to edit it. Is there a vb function which will force the pattern to update when a change is made? I tried the update document vb functions but no change. I will try to get a sample together that is a smaller file size so you can see what I am talking about.

How to change the dimensions of the chosen pattern,
In the screenshot below, I wanted the block pattern to be 0.26x0.5 instead of 0.225x0.450. Is that possible?
I tried to see if the dimensions can be edited but sounds no opting to do this sort of work.

I get the following exception message while debugging, after pasting VBA code into my vb.net project:
"Object reference not set to an instance of an object"
Without going to specifics yet, I commented-out ObjectCollections and the error happened further down in the class.
Is there a different way ObjectCollections are handled in a vb.net class, versus a VBA module?
