When 3D printed, this method is indistinguishable from a modeled chamfer.
If I comment the last two chunks in the union(), the model renders quickly and completely. Note that I see the following in the console window (on this machine - I can't remember if I saw something similar on the other PCs):
Any thoughts on why this is occurring? Any alternatives for chamfering the top edge of a raised SVG image?
It seems to be a function of the size and complexity of the SVG file. I use PowerPoint to modify the original SVG file so that it will 3D print well. I didn't have any problem until a couple of weeks ago when PowerPoint started producing SVG images that were huge and I needed to scale them smaller in the code.
I use Office 360 so there may have been an update to PowerPoint's SVG production at that time. I've tried post processing the image with Inkscape but the render still fails.
