DXF Contour Import

Apologies for the delayed response, and thank you for highlighting this issue. The problem seems to arise when surfaces are exported with colours. In such cases, the mesh is split into clusters based on each colour. This happens because CAD formats like DWG and DXF don’t support textures, only vertex colours.
 
Additionally, CAD doesn’t handle scenarios where a colour ramp spreads multiple colours across a triangle, which can introduce inaccuracies. As a result, we currently support only discrete colours, which can lead to the splitting of the mesh. We understand that this approach can seem pedantic and confusing, and we’re actively looking for a better solution.
 
We’ve seen vertex colour exports in other programs that look good and we always try to give the user what they need, in this case maybe with a warning about the issue of colours that are banded across triangles, and as part of the V7.5 update, we’ll be focusing on exports and examining how to improve this functionality.
 
In the meantime, for your specific scenario, the simplest workaround is to export without shaded colours.
