I have a design I cut extruded onto the top portion of a revolved base. I was wondering if there was a way to do a linear pattern of this design, but make the design proportionally smaller as it goes down the revolved base.
I can think of two options
1. 2015 SOLIDWORKS Help - Vary Sketch
2. 2015 SOLIDWORKS Help - Variable Patterns
VARIABLE PATTERNS!!!!!! I've been waiting on this one!
We just went to 2014 a couple months ago, so I might still be waiting a while.
Glad to see they were finally implemented
Your description of the application is pretty vague. The best approach might depend on the complexity of the cut profile, but using the "Vary sketch" option may give you what you want. The challenge is to minimize the number of dimensions you use in the sketch and try to constrain everything with relations. Then create a relation within the sketch that sets the size of the shape depending on the position along the revolve, like my constraint to the diagonal line. Then as the sketch varies the entire profile scales. Notice in my example I don't have any dimensions on the profile itself.
If you can't avoid using dimensions then another option would be to use the "instances to vary" option, in which case you'd need to select each dimension and indicate how that dimension needs to change from one instance to the next.
edit: Attached my file.
I am doing a linear pattern of a circular pattern. The "vary sketch" option is grayed out of my menu. Is there another way to do this?
if I understand the original concept, do the linear pattern first - then circular pattern that.
(picture(s) would help)
Even when I do a linear pattern first the vary sketch option is still grayed out. I used the bottom edge as the direction for the linear sketch. Should I be using a different reference?
did you rad the help on vary sketch? you have to pick a dimension as the direction for the vary sketch option to work.
what do you mean by "rad the help"?
Also how do you pick a dimension as the direction?
I'm still a little confused on where you clicked on the part to get it to be a direction
The dimension you choose for the direction has to be a dimension associated with the feature you are patterning. When you start the linear pattern, before you pick a direction, select the feature you want to pattern and then it will show all of the associated dimensions on the screen. Now you can go back to the direction input and pick one of those dimensions that are shown.
