If ArtiosCAD imports a PDF with large number of vectors, it crashes when using the Edit tools like the Scale tool.
Symptoms
A user imports a PDF into ArtiosCAD with large number of vectors.
The user then might try to use the Scale tool with all the vectors selected.
ArtiosCAD could potentially crash, that is, stop working and disappear.
Solution
In such a scenario, disable Dynamic Drafting. With so many vectors, ArtiosCAD may have difficult time finding endpoints at various zoom levels of the scale.
With so many vectors, the Dynamic Drafting may prove difficult to use.
The ArtiosCAD development team will correct the issue in a future release.
You can disable this option by default via Defaults > Startup Defaults > Snap Options.
