I wanted to follow the ZClassroom video tutorial on the curved surface brush.
But for me it is buggy.
I tried making a sort of skirt for the cube as in the tutorial. I wanted to see if I could close it to make a skirt without a gap, and when I placed the last curve quite close to the first one (without touching it, though) suddenly the mesh disappeared and ZB crashed.
I restarted ZB and tried again; this time when I tried to change the thickness by changing the drawing size ZB started to connect the endpoint of the last curve to the endpoint of some other curves and the shape got totally distorted, with spikes poking out.
What’s wrong???
