Creating sketch driven pattern in an assembly

[slyfer61]

Hi!

I've been working with no problems with sketch driven patterns, but today I was trying to sketch a driven pattern in the assembly file. Can this be done so I don't have to get inside every part file? 

Here i have 2 different parts, so I wento into the Sketch tab, selected a face in the part 2, projected geometry from some holes of part 2 and 1, and then i went to 3d model tab, put an axis in a hole and then a point. When I go into sketch driven, the feature (the point) can't be selected, and in the sketch it only says 2 points.

Should I just go into the part 2 and do a driven sketch in there for each part ?

How is the part made in the real world?  If the holes are made in the individual parts before assembly, you'll probably want to duplicate that in the model.  Otherwise the holes won't exist in the part file when you go to detail it.

If modeling it in the assembly is appropriate, I would most likely just not bother with using a pattern in this case.  Since you can't use sketch driven patterns at the assembly level, I would just draw the sketch and use it to define all of the holes in the Hole feature, without using a pattern.

Hi! If I understand the issue correctly, I guess you would like to select a part sketch (points) as a reference for an assembly-level Sketch Driven Pattern. I don't believe this is supported. It might be allowed in the earlier releases but it had caused corruption and now it has been blocked.

The only way to do that is to project the sketch point from the part sketch to the assembly sketch.

Many thanks!

Hi!

Yes, i was trying that. Thank you for your response!

I was asking it because in an assembly-level, the tool was available but I didn't know how to use it.

Thanks!
