I need to create an etch pattern for a light guide. I need the spacing to decrease as the pattern grows in length.
Is this possible?
Welcome to the forum. Yes it's possible. I haven't used it much, but I believe selecting the "Instances to Vary" option will do what you want. If you have more specific questions maybe someone that's more familiar with the feature can help.
I appreciate the fast response. that is exactly what I need...............except it wont let me do that with a point for some reason. only with full features. Any idea why or how to get around that? I will eventually make a DWG of this and it has to be point for our laser not circles.
To pattern a point you would probably need to pattern in the sketch. I almost never use patterns in sketches, but I don't think the vary option is available there anyway. If I'm wrong, or if someone else has an idea, maybe they'll reply.
And that is where im stuck because patter options are different in sketch then in feature options .
Could you create a small hole in your part, pattern it as needed, then create a sketch with points concentric with the holes? I don't know anything about modeling for laser cutters so maybe that wouldn't work.
I would suggest searching for "SolidWorks inserting points...." There are macros that will take sketch points from a text file and place them into your sketch. This means you need produce the equations in excel on how your points are reducing.
Does it only have to be points? I can't imagine any new laser machine can't take a curve to produce the route it requires to cut. I imagine your machine is handling the "best method" to go from point to point. If you can take a curve instead of using macros from your excel file use Curves/Curves Through XYZ Points and select browse for file that you made in excel.
