Equidistant to curve |
Scroll |
You can construct a curve that is equidistant from the base curve. The following can be used as the base curve:
•3D curve,in case of composite curve — also separate segment,
•edge,
•sketch line,
•a chain of the above objects in any combination.
|
Using curves with subordinate objects-curves (projection curve, intersection curve, etc.) has particular features. Details... |
To plot an equidistant curve, use the Equidistant to curve 
.
Procedure
1.Set the base curve. To do this, select an object or chain of objects in the graphics area or in the Design tree.
If the specified objects intersect or touch other curves (or edges, or sketch lines), they can be selected either as a whole or in parts, which are divided by intersection/tangency points. This depends on the status of the Select curve parts 
button on the Parameter panel. More...
The name of the selected object(s) is displayed in the Curve field on the Parameter panel. A phantom equidistant curve with default parameters is displayed in the graphic area. The starting vertex of the base curve is marked with an arrow indicating the direction of the equidistant curve construction.
2.You can change the direction of the equidistant curve by clicking the Change direction 
button to the right of the field Curve.
3.Set the method for constructing an equidistant curve using the Offset button group on the Parameter panel:
By direction in space. More...
Along surface. More...
4.If necessary set the name, color and display parameters of equidistant curve. To do this, use the Properties section.
5.To complete the operation, click the Create object 
button.
In equidistant curve appears in the graphic area, and its icon appears in the Design tree.
6.To finish the team's work, click the Finish 
button.

At zero offset the equidistant curve is a copy of the base one. This copy is a single object even if the base curve is a collection of curves. |
Tips
•You can set values of linear and angular parameters in the graphic area using defining points (see Section Defining Points of Objects).
•You can use the geometrical calculator.
•You can assign tolerances to the values of the operation parameters expressed in linear and angular values. To do this, invoke the Tolerance command located in the menu of the required parameter, or click the 
icon displayed in the parameter field (the icon is displayed if a tolerance is assigned to the parameter value). More details on assigning tolerance...
