Using Graphs to Offset a Curve
When you use
Normal to Surface to offset a curve normal to the reference surface, you can select a graph as a reference for the offset. On the
Options tab, activate the
Graph collector and either select a graph or pause the Offset Curve tool and create a graph. The default graph, the unit graph, is a constant line with a value of 1.
After you select or create a graph, enter a value in the
Scale box. Click
to reverse the direction of the graph, if necessary.
The following figure shows a curve offset using the unit graph as a reference:
You can also create a graph to use as a reference for the offset curve. The graph, which you create by pausing the Offset tool and entering Sketcher, does not appear in the graphics window but is represented in the Model Tree as a group (
) with the offset curve.
The following figure shows a user-defined graph:
