Re: [OpenSCAD] Surface() renders but adding any other object doesn't.

Can you share the .png and the value of the above variables?

From my experience surface() uses a lot of resources (memory & hence cpu)

and larger input size can quickly get out of hand.

Admin - PM me if you need anything, or if I've done something stupid...

The TPP is no simple “trade agreement.”  Fight it! http://www.ourfairdeal.org/  time is running out!

Here's the image, and the variables are as follows
height = 0.02; base_depth = 1.0; width = 62; length = 78.8;
I know it's quite large at 620x788 but the thing that puzzled me is the
huge increase in processing time by the addition of a simple cube. I tried
running this on a couple of different computers and had the same problem.

Looks like a bug. As soon as CGAL gets involved.

Even this crashes eventually, consumes all memory;

surface("smiley.png",invert=false,center=true); // smiley.png from the wiki
of surface()
cube(1);
