Example of a model with PolyPaint From Draft applied
How PolyPaint From Draft Works
This button captures the draft angle of a mesh based on its position as viewed by the camera. Once the model has been positioned so that the desired pull direction faces the camera, click Tool >> Masking >> MaskByDraft to generate the PolyPaint.
PolyPaint from Draft colors the model with pure red (R 255 G 0 B 0) and pure green (R 0 G 255 B 0).
Once the draft angle is captured and PolyPaint is applied, this will store and lock the pull direction of the draft. The SetDirection can be changed by clicking Tool >> Masking >> SetDir. Once a new pull direction is established, this requires clicking the PolyPaint from Draft button to update.
The Draft angle can be adjusted in the Tool >> Masking sub-palette settings. After PolyPaint From Draft has been clicked, making adjustments to the draft angle slider requires clicking PolyPaint From Draft again to update.
