Projection onto Surface (3-D)

Sketch > Derive > Proj.

You use this function to create projections of curves or c-edges onto arbitrary surfaces. Upon activation of the function, the Projection onto surface window is displayed.

Proceed as follows:

1. Identify the curves and composite edges that you want to be projected. Activate the No c-edges checkbox if you do not want composite edges to be projected. All identified objects are listed in the Curves window.
2. Identify the surfaces you want. All selected surfaces are listed in the Surfaces window.
3. Select the projection type:
4. metrical
5. perpendicular to processing plane
6. perpendicular to screen plane

4. Click theProjection button to perform the projection.

To remove the entries from the curves or surfaces list, place the cursor on the corresponding entry and use either the DEL key on the keyboard or the Delete command in the context menu.

Clicking opens a menu with further projection functions, and functions for the approximation of circles, ellipses and splines:

	Projection onto plane, Plane from edges
	Projection onto plane, Plane from edge + point
	Projection onto plane, Plane from 3 points
	Projection onto plane, Plane from surface
	Projection onto plane, Select processing plane
	Presetting for projection
	Approximate 3-D polyline
	Presetting for approximation
	Project GE, Individual
	Project GE, C-edge
