AutoCAD Inventor :: Feature Disappears When Circular Pattern Is Applied
May 31, 2013
I created a partial sphere with six features on the surface of the sphere. I then applied a circular pattern to each of the siz features. I called the features r1, r2, ..., r6.
r1, r2, r5 and r6 worked as expected. there are 16 features evenly spaced around the surface.
r3 and r4 are different in that the original feature is missing after applying the circular pattern.
each of the six features is as identical as I could get them. I followed the same build seauence for all of them.
each feature is made up of four objects - cut1, cut2, sweep and dimple. I selected the four objects for a row, then applied the circular pattern.
If I delete the circular pattern for r3 or r4, the original feature becomes visible again.
So, why are r3 and r4 behaving differenly than the other four?
I have tried a number of things, including re-drawing feature r3 from scratch with no change in teh results.

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. also after applied any of these features I can't use trim feature, can I ? but sometimes using the trim feature after applying the Circular Pattern feature or rectangular pattern can be necessary.

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 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 am currently trying to model a multi cavity mould tool. The cavities themselves do not follow either a circular or rectangular pattern.I have modelled one of the cavities using a revolve internal to the tool. I have also sketched out on the upper surface centre points where I need the cavities to be.
I was hoping I would be able to copy the cavity feature, select a base point and then use the centres from my second sketch to place the cavities.
I don't seem to be able to find this option. The copy and paste feature will likely work but it is hugely long winded positioning each cavity individually. Any method I might be able to use to model such a part?

I have modelled a disc, which has 6 cylindrical extrusions in a circular pattern on the disc surface. I want to change the number of occurrences (the "placement") to 9 but the "OK" button is disabled. I get the preview od the 9 occurrences, but it will not complete the command.

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 need to know what sketch is associated to either a "Rectangular"or "Circular"array. This is so I can filter out sketches that are not repeated in an array.
Here is my code so far (Circular Array).
Dim oCP As CircularPatternFeature
For Each oCP In oDef.Features.CircularPatternFeatures
THIS IS THE TROUBLE LINE If sketch = oCP.Parent Then
Set oCP = oDef.Features.CircularPatternFeatures.Item(oCP.Name)
[code]........
I have a simple test part containing an extruded disk (Sketch1) and 8 holes on a pcd (Sketch2). I only want to array a sketch if it is arrayed.

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.

I am using a circular pattern to re-position an internal keyway and am wondering if it is possible to supress the original keyway? Right now I have to give it a 'Placement' value of 2 to get the keyway to shift the amount I want, and as such it keeps the original as well as the new (overlapping them). I wish to suppress only the original one leaving new one...

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.

I am setting up a family of parts that consist of a round disc with a fixed OD and a circular pattern of notches cut into the OD. The notches must go to a certain depth from the center, so those parameters are set. My problem is that I need to control the amount of material left between the notches, along the OD, after the pattern is done. Given the fixed parameters of the major OD, minor OD (3.5" in this case) and number of notches, the only way to control the amount of material between notches is to change the angle. When I set up the sketch to do the notches, I can only get a fully constrained sketch if I assign a specific angle to the notch. I need to be able to set it up so that the angle of the notch varies so the end result is a specifc amount of material left after the circular patter is completed.
In the attached PDF, I show what I have done so far. In this case the OD of the part is 4" and the diameter of the notch at it's closest to the center is 3.5". So basically, I end up with a driven parameter of 0.443. If I assign this value the parameter of d14, I need to make it equal to a ratio of another parameter (let's call it d15) so that d14 = d15*2.. This can only be accomplished by changing the angle.
In my family, the major OD and minor OD remain the same, but the angle must change to retain a specific amount of material between the notches when the number of notches is increased or decreased.
Is there an iLogic rule I can write to control this?

I have a tube which I'm adding a pocket to the outside by removing some material. I then need to array that around the tube. However I need to offset each pocket along the length of the tube. I've attached the tube with one pocket (v2013) and a picture showing the pattern if the surface of the tube was unwraped.

I have attached a jpeg file of a Plate out of a heat exchange.It shows half of the Plate but it is identical shape for top and bottom.I am able to create the solid shape but i need creating the numerous patterns onto the plate.How would i place the pattern feature onto the Plate?
Also from the picture there is a gasket.Would this be made as a separate part and placed on the Plate in a assembly file?Would the gasket be best made using sweep function?
I have created the plate as a solid model but would Sheet Metal also work or even be a better choice?

I have a library of blocks that I built for our company to use. We recently upgraded from 2013 to 2014 and boy did it throw our library for a loop!
There is a check box (reflectivity) that leaves the materials black when the drawing shade mode is changed to Realistic (unless you go in and uncheck the reflectivity box) and while I have figured out how to alleviate that issue (by unchecking it on our tempate and saving it) I am still having a materials issue with our blocks.
I can open the block (and turn on Realistic mode) and all the pieces have their materials like they should. I then open a new drawing and insert the same block into the drawing .. one piece is sans material.
I cannot for the life of me figure out why it's there on one drawing but it gone when inserted. The new drawing has been purged and doens't contain anything it shouldn't.

I have a Hole that cuts through 2 solid bodies, a gasket and a cover plate. I want to pattern the hole in BOTH solids at the same time, but the pattern feature dialog box will only let me select one solid at a time. I could pattern the hole in one solid before projecting to the other, but the quantity of the holes can change. When the quantity of the holes changes only the holes from the initial pattern are projected. For instance if I have 10 hole initially and it increases to 12 the 2 new holes do not project to the second solid body.

Following on from my post regarding a sheet metal component that was unable to create a flat pattern due to creating the component in an assembly; URL....I have found out that it wasn't the in place component that was the problem it seems to be the loft and sweep feature that cause this problem. I have thought about using the extrude feature (as this works) to create the shape and then cutting the ends to get the angles I want but that would be time consuming.
I have set up the sheet metal rule to be 3mm mild steel, any way creating this component and being able to create a flat pattern.

We are using Inventor 2011 and I would like to make a small app that allows my users to graphically select one or more occurrences of a rectangular pattern feature Then allow them to suppress them if desired.
I have determined the code to loop through the pattern occurrences and toggle suppression for any instance. What I do not know how to do is determine which occurrences have been graphically selected.
At this time I am only concerned with round hole features. (Perforated metal)

I am trying to create an infographic that has a circular pattern. I'm hoping there is a streamlined process that allows me to start with a linear set of bars/pattern (with vertical text) and then automatically transforms the set to an evenly-spaced radiating pattern.
