Clipping Area Doesn't Nest When Using 2D Array
« on: November 20, 2021, 04:50:08 AM »
I've noticed that if I try to nest generators, whatever clipping I used in the sub generator does not get transferred to the next generator up if the sub generator is a 2D array.

For example, I'm using a 2D array to build a brick pillar that has a diamond pattern knocked (clipping) out of the bricks. The clipping works fine when generating the original, single, array, but as soon as I try to generate that array with any new generator, everything shows up except for the clipped out area.

Is this simply not possible with 2D arrays currently, or am I missing something?

I have, however, noticed this is not an issue if using 1D linear generators as the sub generator.

You're right, it would appear that internally the array is moved to world origin when nested, moving it outside of the clipping spline's influence.

In my tests, I could fix it by aligning the clipping spline's pivot to the world's origin (and then reset the XForm). If this doesn't work, if possible, please upload a sample file and I'll take a close look.

Thanks!

Thank you, Paul. Resetting XForms was indeed part of the solution. In addition, it would appear that in order to nest the effects of a clipped array, the RC object itself must have a zero/zed point origin (0,0,0).
