AutoCAD Inventor :: Helical Component Pattern?
Apr 19, 2012
I have a sheetmetal assembly with helical shaped parts. I need to place about 50 little brackets and some corresponding rollers along the length of these helical pieces. The spacing is even so a pattern would be perfect, except I don't know how to get it to follow the shape of the part. The brackets are located to slots in the helical parts which were made with a rectangular pattern in the unfolded state. I tried to do a "feature pattern select" but it only saw the rectangular pattern as it is in the unfolded state (a straight line). I then gave up on patterns and started working on manually mating them into place but realized that the geometry of the slot was distorted (theory) and didn't leave me with any useable surfaces.

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 a component pattern with 3 components in it and I need to remove one of the components from the pattern. How can I modify the pattern through the API? I have tried various things but I do not appear to be able to change the pattern.

In an assembly, is there a way to pattern a component in the X, Y and Z directions? I need to make a certain number of components, and each instance changes by the same delta x y and z. The dialog box will only show me column and row options.

Pattern component is great but sometimes I have to pattern the same part several times to different dimensions in the same direction. For example: I have a part that has to go the left 26', then again at 29" and then again at 37". Other than manuallly constraining this 3 different times I've had to Pattern Component the first one at 26", then change the 2nd one to Independent. Then Pattern component that one to the 29" dimension. Change that 2nd one to Independent and pattern component that one to 37". It saves a lot of time but if I have to increase the model they are going on I have to start all over. Is there a command or something that will do this? I understand that a pattern is equal lenghs so maybe I am looking at the wrong command for what I am needing to do.

I have a few components in my assembly that I want to turn off under certain conditions. Using Component.IsActive, I can turn on or off an instance, but some of the components are in a pattern, and I want to turn on or off all instances of the component. To add to the challenge, the component patters are driven from Excel, and the quantity of parts changes.How can I turn off all of the instances of a pattern?

I have a rectangular component pattern which started out with all components. As more structure was added around it I started supressing different elements to suit, now a piece of structure has gone thru element 1 but i dont seem to be able to supress it... is there an easy way to get rid of element 1 without having to redefine the pattern? (redefining causes me other problems)

How to modify the code below to delete suppressed parts in a pattern (entire pattern)?
Dim oComp As ComponentOccurrenceDim oComps As ComponentOccurrencesoComps = ThisDoc.Document.ComponentDefinition.OccurrencesFor Each oComp In oCompsIf Component.IsActive(oComp.Name) = False Then oComp.DeleteNext
Code works fine if there are single instances of the part. It throws a error when you have a suppressed pattern.

my create a circular pattern in an assembly that maintains the orientation of the part being patterned.
This is for foundation plates. There are 3 plates. The plates are square, and have bolt holes in the corners of the plates. Since there are 3 plates and its going around a circle, the angle between the plates is 120 degrees.
Now, Ive been trying this for some time now and what is happening is the firs plate is fine, but then the second and third plate are rotated around their center axis. I would like it to simply remain as inserted and constrained within the assembly.
I have attached a picture to be more clear about what I want and what I'm currently getting.

We are having an issue when we replace a component in Inventor Pro 2012. When we replace a component, the name in the browser does not update to the new component. We've even tried to close and re-open the Inventor assembly and that does not work. We end up manual double clicking the name in the browser and type in the new component name.

II need a way to tell if a component occurence is a virtual component.
I'm using a For Each loop to cycle through all of the components in an assembly, and if the component is itself an assembly to set the LOD to "Custom". I'm using the definition document descriptor object for this. It all woks fine until the loop comes across a virtual component which doesn't have a definition document, so I need a way to check if the component is virtual and needs to be skipped.Here's the
Option ExplicitImports Inventor.LevelOfDetailEnumSub MainiLogicVb.UpdateWhenDone = TrueDim doc As AssemblyDocumentDim oLOD As LevelOfDetailRepresentationDim oAsmCompDef As ComponentDefinitionDim oComp As ComponentOccurrenceDim oComps As ComponentOccurrencesdoc = ThisDoc.DocumentIf.

I am trying to make port rims for pipes that can be swapped in and out of an assembly. However, the ports will all be different sizes and located differently so I need the cut to be part of the port rim component, but affect the entire assembly it is part of. I've been trying to get this to work for the better part of a day now,Here's a picture of what im talking about. I'm running Inventor 2008 by the way.

I am trying to recreate and 3D model the impeller of a heartmate II LVAD (URL....) but I am having problems with the sweep along the helical path. The profile is the vertical line and the path is the helix. I want to use a surface output for now. I had to use Solidworks to generate a variable pitch helix and import into Inventor.

When showing a gear in an inventor drawing they look good, but showing a helical gear SUCKS! The display, I realize, is very realistic to what you would see if you held the gear in front of you at this view point or that.
Problem is, I put a helical gear drawing on the shop floor and they machinist wonder why I have two rows of teeth on the gear (since it shows the front face and the helix'd gear teeth).
Any way to remove said offending gear teeth?

I'm building a product configuration which includes some helical curves. I want to find out how I can change the direction of a Helical curve feature in a 3D sketch.
Variables like pitch and diameter are parameters, but the direction isn't.

I have an assembly which has a few components suppressed.
My end results is another copy of the assembly (with copies of the all the parts) in another directory
Now i am able to create copies of un-suppressed parts using; (this allows me to SaveAs assembly components which are not suppressed)
DocumentsEnumerator = ThisDoc.Document.AllReferencedDocuments
And save a copy of the assembly using
ThisDoc.Document.SaveAs
I also added the fllowing snippet (which I am not sure what is does), but it does not work for me
Component.SkipDocumentSave = true
When I open the newly created assembly, I still see the suppressed components in the model browser
I want to either;
Skip saving the of the components in the model browser (i.e. the Assembly)
OR
Delete the suppressed parts in the Assembly, so that they do not save altogether

I'm trying to draw a helical staircase with a bottom plate underneath the steps. Drawing it isn't a problem. I used a sweep with helical curve. Then I converted this part to a sheet metal. But then inventor doesn't want to unfold it. how I have to make a flat pattern from this one with the necessary bending lines?

I would like the pattern to follow the rotation of the component when inserted onto the project. I can achieve it with model pattern but I would like to use drafting pattern because we need to show them on different scales.The diffuser family consists of a detail family in order to show the pattern. The pattern is already set to align with object and it still does not work.

I have generated a gear set using inventor. Now I would like to 3d print the gears. I have uesd the export tooth shape to get the true tooth profile. now I am attempting to use the coil feature to generate the helical tooth. The problem im running into is in the coil tool I can only give it a Revolution and height dimension. The hight is the width of the gear, but I am having a problem converting the helix angle to the "Revolution" perameter. I have read other posts and they say that it is Helix angle / 360. I have tried that and then compared it to the original gear generated by inventor and it is not even close. I need to do this on in internal gear and match it to an external gear.

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.

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.?

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 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.
