SurfaceParting Plane
The Parting Plane command enables you to create a parting plane: a surface located around the parting line (generally made of a chain of curves) that is very useful when creating molds.
In molding, a draft surface is very often requested as a shape modification to facilitate the part ejection. The parting "plane" is the area of the mold that closes the cavity. It is generally generated by moving a straight line perpendicularly to the direction of ejection (or pull direction) and to the tangent of the parting line. This method cannot absorb parting "line" tangency discontinuities and even often generates surface tangent plane discontinuities on tangent continuous parting "line".
think3 applications offer an advanced method that tries to absorb parting "line" tangency discontinuities thus generating an easier shape to be obtained using Numerical Control tools. When there are too many contradictory constraints that make the result impossible the user can choose the standard method.
| Associativity The surfaces created using this command can be associative: associative surfaces are Skins, that is open solids, retaining a link to the base curves, so that if you modify the base curves the surfaces will be modified accordingly; they have a history and are displayed in the Model Structure. See " Associative Surfaces (Skins)" for details. |
