Check for crossing segments before axlDBCreateShape

Ejlersen

Hi

I'm reading in a file to create a shape, my problem is that if the shape is selfcrossing then I'll get an error

E- (SPMHDB-187): SHAPE boundary may not cross itself.

This terminates the program, so is there a way to check if a path is crossing itself before committing it to axlDBCreateShape so that I can avoid the program from terminating.

If so, is there a way to detect the coordinates for the issue and maybe even get it to heal it self?

Best regards

Ole

  • Great to see you are still around Chris! I would be looking at the source of the problem. If you are creating a path, look at the segments. Arcs will cause you some problems with analysing segment by segment. Your routine shouldn't crash. You should be able to detect the nil result of the command and provide some debugging. Dave
