Curve Driven Pattern Not Working

Question asked by Alex Haid on Oct 26, 2015

Hi,

 

I want to make a graded density foam. I made this easily with linear feature patterns with increment dimensions. Here is a picture:

Now I want to pattern this type of structure around a hemisphere. I have tried using the curve driven pattern to do this. My pattern is a single linear pattern. I have tried using a arc in a sketch and a swept surface as profiles. However each time I click the green check mark, solidworks briefly loads and then nothing happens. I am not sure what I am doing wrong. Ive attached a screenshot. I also noticed when I turn on full preview, the preview disappears completely.

My linear pattern has error saying that dimensions or relations in the sketch do not have the model geometry to relate to.

 

 

Thanks, sorry if I'm unclear,

Alex
