Draft Trimex

Description
The Trimex tool trims or extends Draft Lines and Draft Wires so that they end at an intersection with another line or edge.

The Trimex tool also extrudes faces created from closed wires. In this sense, it's similar to Part Extrude and to PartDesign Pad.



How to use

 * 1) Select a wire you wish to trim or extend, or select a face you wish to extrude.
 * 2) Press the  button, or press  then  keys.
 * 3) Click a point in the 3D view, or enter a distance and press.

Trimming or extending is decided from the position of the pointer.
 * If the wire is short it can be extended to approach and cross another wire.
 * If the wire is long and crosses another wire, the excess length can be trimmed.
 * If the pointer is moved over another object or edge, the trim-extend operation will snap to that object or edge, so that the resulting wire ends exactly there. This snapping works even without Draft Snap modes active.

When the selected object is a face, the Trimex tool switches to mode. In extrude mode the extrusion is done in the direction of the normal of the face. For example, if a rectangle lies on the XY plane, it should be extruded in the Z direction. To do this correctly, pressing the key may be necessary to constrain the distance to the Z direction. Alternatively, hold the key to extrude in any direction that is not the normal.

Options

 * Press, or  to constrain the point on the given axis.
 * Hold to restrict the operation to the current segment, and avoid picking another one.
 * In the case of extruding a face, hold to extrude in a direction that is not the normal of the face.
 * Hold while trimming to invert the direction of the trimming, that is, the other end of the wire will be cut.

There is no programming interface available for the Trimex tool. See the Part Extrude tool for extrusion of faces and other shapes.
