3D Path as Projection on Face or on Body

Calling the command:

This method involves creating a 3D path as a projection of an existing 3D path on a face or a set of adjacent faces of a sheet or solid. In this case, the source path may be non-planar, and its projection does not necessarily have to fit entirely on the selected faces. The projection vector is set either by a single 3D object capable of determining the direction (a straight 3D path, edge, LCS, working plane, etc.), or by using two geometric points (3D nodes, vertices, etc.). If a body is selected, a 3D path is projected onto each of its faces. The resulting elements (the results of projecting a 3D path onto the selected faces or body) are combined into one 3D path. Elements that cannot be joined are discarded.

1 – source 3D path; 2 - the source body (face); 3 - objects defining the projection vector; 4 projection of the source path

If the projection vector is not specified, then the projection is built along the normal to the selected face, and if a set of faces is selected – along the normal to the nearest face.

1 – source 3D path; 2 - projection of the source path along the normal to the face; 3 - projection of the source path in a given direction (along the normal to the plane)

The face or operation body are selected in the 3D scene by . An operation body can also be selected in the 3D model tree by picking the intended operation in it.

The source 3D path is selected by the option:

The projection vector can be defined by two 3D points with the help of the options:

The projecting vector can be defined by a single object using the option:

To undo a specified direction, use the option:
