PathCast

Projects a curve onto a surface in order to obtain a 3D curve on surface.

How to use

1. Click the PathCast icon or choose the Tools > Curves > PathCast command.

2. The program console prompts Pick curve.

3. Pick the curve you want to be projected along a vector on the target surface. Once picked, the curve turns green.

4. The program console prompts Pick surface.

5. After you pick the target surface, the program will display it in green and the curve projection in magenta.

Note: By default, the curve is projected along both the curve normal and its opposite, but you have several options to modify this (see Projection Direction in the Options list).

Options

Curve

To change the curve to be projected.

Views / Modeling Tool panel. Switch the Replace check button on and pick another curve in the scene.

Surface

To change the target surface.

Views / Modeling Tool panel. Switch the Replace check button on and pick another surface in the scene.

Projection direction

To determine the vector along which the curve will be projected.

Modeling Tool panel. Switch the chosen radio button on. You have the following options:

X axis. The curve is projected along the X-axis.

Y axis. The curve is projected along the Y-axis.

Z axis. The curve is projected along the Z-axis.

Current view. The curve is projected along the axis that is perpendicular (normal) to the current active view.

Curve normal. The curve is projected along its normal.

Inverse curve normal. The curve is projected in the opposite direction with respect to the curve normal.

Both curve normals. The curve is projected along both its normal and opposite direction.

Projection start point

Projection end point

To modify XYZ coordinates of the projection start and end points, hence allowing you to determine a custom vector along which the curve will be projected.

Modeling Tool panel. Type the values in the XYZ data fields and confirm them by pressing Enter.
