Hi,
I found an issue of 18.0.2.
An obj shape file fails to import into 18.0.2 that object is invisible.
Import into 17.2.5 is fine.
In 18.0, we updated the assimp library to a newer version. This included an updated obj importer.
This appears to be a bug with how the importer is handling this particular obj file. The latest obj importer is throwing an exception on an out-of-range vertex index, but the older obj importer silently handled it just fine.
For now, you can convert the file into a different format in order to render it correctly.
Attached (pg.ac) is the same shape saved as an ac file using AC3D.
Also attached (pg2.zip) is the same file saved as an obj from AC3D.
Both of these files, exported using AC3D, import correctly into FlexSim.
On closer inspection, the issue with the newer importer seems related to the comment on line 8 that contains a backslash:
If you remove the backslash, then the file imports just fine:
The out-of-bounds error seems to be related to the importer interpreting that backslash as continuing the comment onto the next line, thus skipping the first vertex.
