SolidWorks 2017 SP5.0-generated STL model triggers DoesNotMatchExactly("facet normal")
Yen-Yung opened this issue · 2 comments
Hi,
I used to be able to import SW-generated STL files using CADMesh 1.x a few years ago. Recently I updated to 2.0.2 and presumably also a newer version of SolidWorks, SW 2017 SP5.0, to restart the project. I am getting error
The CAD file appears to contain incorrect syntax:
Error around line 1: Facets are indicated by the tag 'facet normal'.
from DoesNotMatchExactly("facet normal"). Is there a setting I missed when converting SW parts to STL or is this a bug? I am also attaching the STL I tried here. Thanks!

update 200707: I can import your bunny.stl, so it must be something wrong with SW-generated STLs...
update 200708: found the problem being the first line of the STL file
solid assembly - 300K_can-1
facet normal -9.993034e-002 0.000000e+000 -9.949945e-001
outer loop
vertex 1.867302e+002 5.450940e+001 3.775120e+000
vertex 1.765321e+002 1.742470e+003 5.317435e+000
vertex 2.131847e+002 1.742470e+003 2.110749e+000
endloop
endfacet
...
It doesn't like the original name "assembly - 300K_can-1," nor "300K_can" or "300Kcan," but accepts "Kcan" and "kcan." I guess numbers and special characters are not allowed.
Thanks for reporting this. It looks like only names with letters are accepted. I will fix this right away.
@Yen-Yung The CADMesh.hh header file in the master branch should fix this problem for you now.
