The 3D Curve Offset function enables you to select a series of edges from a solid part or face part, offset them through a specified positive distance, and combine the offset edges in a wire part.
The figure shows how the perimeter edges around one face of a solid body are offset through a specified distance and then combined in a wire part.
When you create an offset curve from a solid part, the offset curve is defined by:
• the intersection of the two faces adjacent to the selected edge (A).
• the specified offset distance.
When you create an offset curve from a face part, the offset curve is defined by:
• the offset of its adjacent face (A).
• the corresponding edge of the offset surface.
To create a 3D curve by offsetting existing geometry,
1. Click 3D Geometry and then, in the 3D Curve group, click More next to Spline 3D.
2. Click Offset Curve in the Indirect section. The Offset and Select dialog boxes open.
3. Type a Part name.
4. Click Edges and select the edges with the
Select tool. To select all the edges of a face, click By Face in Method in the Select dialog.
5. Type the offset Distance.
6. Click to complete the operation.
