slab adjusting along a curve?

Anonymous
Not applicable
Hi, is there a possibility to adjust a slab after an arc / curve?
I mean just as the split does (cutting on a straight line ) but along a curve, in this case along the orange arc.

Any workaround than manual adding points and then curving is welcome

Split will only use straight lines, but you have a good idea. I will pose it to our designers. But for now you must use different methods to achieve what you are after. I have 2 ideas and maybe more experienced users have other ideas.

A. Use the Subtract from Polygon and Magic Wand to remove the unwanted portion of the slabs. This requires that your perform the operation on each slab individually.

OR

B. Convert slabs to a Morph element and use boolean subtraction to remove the unwanted portion:
1. Select all slabs and Convert to Morphs.
2. Then use a Union boolean operation to make the multiple Morphs into one.
3. Use the line tool and make an enclosed shape with the arc.
4. Use the Morph tool and space click the enclosed shape you just made.
5. Extrude the shape to intersect the Morph slabs.
6. Use Subract boolean operation to remove the unwanted portion of the morph. The extruded arc Morph will also be deleted in the process.

I'd go for option A. If you make the curve a complete circle it wouldn't matter which order you magic wanded the subtraction.

Cheers,

I chose to use method A. I think it's cleaner and easier.
Thank you
