Projected Polyline

This command creates a CAD curve and project it onto a mesh. To do this, you click points on the mesh, a curve passing through these points is computed and then projected on the mesh. The result is a polyline.

1. Choose either you want to Close or not the curve and its corresponding polyline.

2. As the curve is projected onto the mesh, you can choose the direction of projection:

   1. Uncheck Custom direction to project according to the shortest distance.

   2. Or define a projection direction.

3. Click some points in order to compute a curve. This curve will pass through all clicked points. After that the curve is projected on the object and the result is a polyline object: each point of the polyline is on the mesh.

4. Use DEL key to remove last added points.

5. After the projected polyline creation, you can move control points to adjust the line as needed. To do this, you can click on a control point to select it and move it by drag and drop. When you release the moving control points, the function recalculates locally the location of the control points to have an optimum layout.

6. If you move the first or last control point of the contour, you can snap them on another curve. To see if the connection is made, check the color of the control point. Color is updated in real-time during node movement.

   • Red color means that the control point is not connected with other objects.

   • Dark green color means that the connection is made with another line extremity.

   • Light green color means that the connection is made with another line.

   • Yellow color means that the connection is made with a mesh border.
