AutoCAD Inventor :: How To Create Symmetric Pattern Of Components Equally Mid Plane
Sep 14, 2009
I'm using Inventor 2009.
Imagine a flat, rectangular plate with origin plains located symmetrically down the middle of the plate. Place a component, say a small cube, and constrain it to the face of the plate and the origin planes so that it too is symmetrically located. I now wish to pattern this cube about the midplane and create a total of five instances. I select "Pattern Component" in assembly mode and select the cube. For direction 1, I put in two instances and select an edge of the plate so that the pattern is taken to the left of the midplane. For direction 2, I again select two instances but pick an edge so that the pattern is taken to the right of the midplane. I now should have a total of 5 cubes but I don't. I have 6.
The second pattern is actually a repeating pattern of the first which, in the end, creates too many cubes. Visually, it looks correct because the cubes are placed excatly on top of each other. Numercially, like in BOMS, it is not correct.
Is there a way to avoid these duplications?

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?

When I use the command MIRROR to create a symmetric component from existing ipt there are two problems:
1. in the existing ipt dwg the dimensions were lost, when I update the dwg;
2. in the iam that contains the mirrored component the constraints were lost, when I update the dwg.

I want to arrange these outer circles in a corcular pattern at equal distance and at equal angle from each other without using circular patten feature in assembly tab. How do I do that.
The reasomn I dont want to use circular pattern in assembly tab is if I do that then, I cannot change color of each outer circle separatly If I change one color it changes color for all of these whcih i dont want.
I want to have each outer circle of different color.

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 have a pattern of reference components, but the quantity of the pattern can change based on certain criteria. When the quantity increases or decreases, I need each pattern element to have its BOM structure set to reference.
The problem is, even if the original pattern element is set to reference, each subsequent element comes in as normal. This causes the BOM quantities for that component to be reported incorrectly in higher assemblies.
Is there some iLogic or VBA code that will automatically set each component in a pattern to BOM structure "Reference", even if the pattern quantity changes?

I've created a model of a monkey in Maya. The model is symmetric along the X axis - however, the UVs are not.
I've just gotten to the stage where I'm rigging my model and discovered that I'm missing polygons for a finger joint on both hands. I'd like to insert some edge loops for this extra joint. I could do this by just adding the loops by hand, but if I do that, they'll be a little bit off and my model will no longer be symmetric. Alternately, I could delete the right half of my model, add the loops on the left half, and then mirror and merge my geometry. This would preserve the symmetry, but completely destroy the UV info on the right half of my model.
This seems like it would be a common modeling problem. Does Maya have a way I can add the extra cuts to my model, preserve symmetry and not force me to redo the UVs and texture map for my entire model?

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?

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.

create a plane and mirror a solid?
I am planning to have the following workflow:
Plane creation:
Through the z-axis and at an angle of 7,5° to the XZ-Plane
Naming the plane - Mirror Plane
Turning off the plane visibility
Mirror solid:
Add mirrored solid to the existing solid
Here is a sample ao the code...
Dim oDoc As PartDocument
oDoc = ThisApplication.ActiveDocument
Dim oCol As ObjectCollection
oCol = ThisApplication.TransientObjects.CreateObjectCollection
'This does not work...
oCol.Add(oDoc.ComponentDefinition.SurfaceBodies(1))
'Here I want to create a new plane
Dim oPlane As WorkPlane
oPlane = oDoc.ComponentDefinition.WorkPlanes(1)
Dim oMirror As MirrorFeature
oMirror = oDoc.ComponentDefinition.Features.MirrorFeatures.Add(oCol, oPlane, False, kOptimizedCompute)
I have also attached a simplified part file where the code has been copied inti the iLogic browser

I am trying to create two plane's one after the other like it is done in this video tutorial.
[URL]........
My problem begins with me only having 1 point on the part to pick for my 3 point plane command. In the video there is no bit where you are supposed to create a point but I'm thinking I wont be able to duplicate without doing something like that.

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.

I want to create one Spur Gear in inventor with equations such that i can build more gears from this base model using excel table. For. Eg. I would like to create a gear with 40 No. of teeth of 10DP, and 20°PA, with Pitch Circle Dia, Base CIrcle Dia, Tooth Thickness based on spur gear calculations.
Now i would like to create a series of such spur gears with varying no. of teeth, i.e. 42, 44, 46, 48, 50..etc. Now if i change the No of teeth ,Accordingly the gear should modify its pitch dia, Base circle dia, Tooth Thickness which would be noted in the Equation.
how to create thes equations and use these in creating gear with different no. of teeth.
I have shown below list of gear data for various no. of gear.

Is there a way to create asymmetric pattern, both circular and rectangular, in assembly environment. For example, I have a component which I want to circular pattern at different angles rather than fixed angles. Let's say 3 components around the circular pole- angle between 1 &2 - 175deg, angle between 1 & 3 (in same direction) 265deg. I understand that this will violate the definition of pattern but would be nice to have such feature. If I am not mistaken, Solidworks has that ability to do asymmetric pattern which I have used years ago.

I created a 12-sided polygon shape in the sketch mode. I created one line, fully constrained it and then used the circular pattern to finish the shape. Why can't I extrude the shape?
I have attached the file. It's a pretty basic shape. I don't understand why it wouldn't work...

I can't get Inventor to create a flat pattern of the attached sheetmetal part. It's a pretty basic part, just five folds. I'm not getting any error issues - when I go to the flat pattern it just shows the folded part (picture attached).
I assume it has something to do with the way I folded it and the notches, etc. Inv makes to accomplish the fold. I'm using Inventor 2013 on Win 8.

I am currentrly trying to pattern a series of square holes that form a simple aztec pattern (attached). I am planning to fill the holes with black dye/paint in order to represent the aztec pattern (hence the holes need to only be about 5mm deep.
The pattern itself should be about 2cm*2cm.Is there a way to use an image such as the one attached and make it automatically translate that into holes, or do I have to draw it all manually? If I do have to do it manually, c how to create square holes?

I need a code to generate the Flat Pattern in VBA.
I made an app who sets the specific material and I would like to unfold the folded part at the same time.
I tried this code, but not works:
Dim partDoc As PartDocument
Dim sheetMetalDef As SheetMetalComponentDefinition
If (Not sheetMetalDef.HasFlatPattern()) Then
sheetMetalDef.Unfold
End If

I recently switched to Inventor 2012 from a previous version. I cannot find the create flat pattern command. Some of my coworkers were able to customize their RMB menu to have this command, but I am not even able to do that! (They don't have the command on the ribbon, either.)

It works fine with other parts, and I've created & deleted the flat pattern for this part before, but for some reason, it now won't work.
It won't let me upload the file, as it's too big, so I'm going to try uploading it in parts...
