Hello Travis,

I just tried out the "export edge lines to POVRay" feature of LDView 4.5.

It sadly is broken: it outputs a syntactically invalid *.pov file because the generated file contains a stray "#end".

Here is the output I got, the line I tagged with "SYNTAX ERROR" is wrong.

I also noticed that logic for the switch LDXSkipEdges is wrong:
it currently is:

Code:
#if (LDXSkipEdges = 0)
	object { LDXEdges }
#end
	object { LDXConditionalEdges }

but IMHO should be

Code:
#if (LDXSkipEdges = 0)
	object { LDXEdges }
	object { LDXConditionalEdges }
#end

Code:

Thank you for the report. I have created an issue on GitHub:

https://github.com/tcobbs/ldview/issues/81

I will investigate.

thanks for the quick reaction, awesome.
I have attached a small example for you there.
