Comments
Great article, very useful along with the DraftingDemo sample to get started with 2D drawing. Some features are a bit cumbersome, like linear dimensions. Is there any out-of-the-box function to draw fillings?
What do you mean by "draw fillings"? Hatch patterns?
Fills, not fillings, sorry. Yes, like hatch patterns.
Unfortunately, we don't support them natively, we only manage the import/export in DWG/DXF file formats
Grazie Simone
Is there anyway to change units?
For instance, if we specify dimensions in inch, but want to display in millimeters...
