Usage

1. Select a NURBS curve, and in CAD Mode, select Offset Curve from the Toolbox's CAD editing tools.
   
   
2. Drag in the Figure Window to create a new curve offset from the first.
   

Tool Parameters

Reference Plane

Select the XZ, YZ, or XY plane to use as the reference plane for creating the offset curve.

When using the mouse, the plane used for the initial drag becomes the reference plane.

Distance

The distance to offset from the original curve.

Style Settings

Sides

Select either Single Side or Both Sides for the offset.

Single Side

The object is offset only in the direction dragged.

Both Sides

The object is offset on both sides of the original line.

Close Side Edges

Connects both ends of the two new offset curves, resulting in a single curve.

Repetition Settings

Multiple offset curves can be created at once.

Count

The number of times to do the offset operation.

Slope

The offset distance ratio. Enabled when Count is set to 2 or more.

Distance to

Select Nearest Line or Farthest Line for the Offset Distance display. Enabled when Count is set to 2 or more.

Nearest Line

The offset repetition is done with spacing between lines equal to the specified Distance. For example, if Distance is set to 100 with 4 repetitions, the outside line will be 400 away, with spacing of 100.

Farthest Line

The offset repetition will be done with spacing as a division of the distance. For example, if Distance is set to 100 with 4 repetitions, the outside line will be 100 away, with spacing of 25.

Shift Settings

These settings adjust the height of the offset. Enabled when Count is set to 2 or more.

Height

Sets the offset height of the distance.

Slope

Sets the offset height ratio.

Height to

Select Nearest Line or Farthest Line for the Offset Height distance.

Nearest Line

The offset repetition is done with spacing between lines equal to the specified Distance. For example, if Distance is set to 100 with 4 repetitions, the outside line will be 400 away, with spacing of 100.

Farthest Line

The offset repetition will be done with spacing as a division of the distance. For example, if Distance is set to 100 with 4 repetitions, the outside line will be 100 away, with spacing of 25.

Apply

Creates the offset curve. The original curve is left unchanged.

Cancel

Cancels creating the offset curve.
