Creates curves-on-surface at the boundaries of out-of-draft areas.
Some manufacturing processes, such as injection molding, impose restrictions on the shape of an object. To avoid problems, understand the following concepts:
Select either Rotation or Vector.
Enter 3D coordinates to define a direction in which the object would be removed from its mold.
For example, if you want the pull vector to run along the Z axis, enter 0, 0, 1.
Enter the draft angle.
If the angle between a surface point and the pull vector is less than this value, the surface point is out-of-draft, and is colored pink.
If the angle between a surface point and the pull vector is more than this value, the surface point is in-draft, and is colored green.
The quality of the curve-on-surface projection, from 1 to 6. The higher the value, the more precise the result. Use low values for draft quality, use higher values for final results.
Enter the name of a vector/plane to position/align the manipulator with it. (You can also click a vector/plane to align the manipulator with it. Or you can select the vector/plane and the surface before selecting the tool.)
Draw fast polylines instead of curves-on-surface.
These lines are mainly for display purposes. Although you can pick them (to delete them, for example), you cannot use them to create geometry.
When Auto Recalc. is off, use this button to update the curves on surface to correspond to the current options.
Undo all the changes made by the tool and return to the original surface.
Finish creating curves-on-surface on the current surface and prompt for a new surface to evaluate.
