So I need to vary the spacing of a single line sketch. I have a sketch of a vertical line, and I need to repeat this line in a linear pattern, but the spacing needs to decrease for each instance. Solidworks 2016 doesn't seem to include "instances to vary" for a linear sketch pattern as it does for linear feature pattern. Any way around this? Thanks

Hello,

I'm not in front of SW at the moment, I'm on 2017 and I can't remember for sure, if 2016 actually had the Instances to vary option, but 2016 help says it does:

As an alternative, you can create several planes normal to your lines' sketch plane and the relate each of your lines coincident to a plane.

Each plane's position from the first can be programmed in the Equations dialog if you have an algebraic formula for this since your OP states a diminishing spacing.

Removing instances may be more problemmatic since the spacing is constant.

Cheers,
