Unfolded curve |
Scroll |
A curve (or point) lying on a cylindrical or conical face can be unfolded onto a flat surface. In the result, a new curve is built in the model.
Unfolding curve is a reverse process to folding.
To unfold a curve onto a plane, use the command Unfolded curve 
.
Step-by-step instructions
1.Specify a cylindrical or conic face in the graphic area. The name of the specified object is displayed in the Surface field on the Parameter panel.
2.Specify the objects that need to be unfolded. The curves lying on the specified face can specified, the edges of this face, as well as points belonging to the face.
The specified objects are highlighted in the graphic area, and their names are displayed in the Curves/points field on the Parameter panel.
3.Specify the plane on which the curve (curves) needs to be unfolded, using one of the following methods:
•Specify a flat face or plane in the graphic area that is tangent to the specified face. The plane can also be placed in such a way that it can be transformed into a plane tangent to this face by a parallel movement.
•Build an auxiliary plane of the required position. To do this, press the Draw plane button 
to the right of the Scan plane field.
The name of the specified object is displayed in the Scan plane field.
A phantom of the unfolded curve (curves) is displayed in the graphic area.
4.You cat set the name, color, and displaying parameters of unfolded curve. To do that, use the Properties section.
5.To complete the operation, click Create object 
.
In the graphic area, an unfolded curve appears, and in the Design tree, there is an object with an icon and subordinate objects corresponding to the number of separate contours within the curve.
6.To complete operation of the command, click Finish button 
.
