Manipulating Entities by Attaching

Move or copy the selection group by attaching it to another entity.

\align

This command is aimed to be used in 2D XY plane to work as fast as possible. When there is no selectiongroup you will be prompted automatically to select entities. Enter two origin source points followed by two target points to be aligned in a new direction.

\mcatt

This command is aimed to be used in all planes in 3D. This command moves or copies all the entities in the selection group to a new location and orientation in space. The relative displacement and rotation are determined by two planes. Using sets of three points, you specify a from plane with an inclination or location relative to the selection group, and another plane defined as the to plane. The system then moves or copies the from plane — together with the selection group — to coincide with the to plane.

The defined displacement and rotation control the relation between consecutive copies. The selection group keeps its internal organization and relation to the first defined plane (from plane). This command is useful for creating elements, such as staircases, where the desired relation between copies of a set is a combination of translation and rotation.

Operation

Specify a plane on the selection group that you want to attach to the new location. Specify three points that define a plane on the selection group.

Then define a new plane location and orientation, by an additional set of three points, relative to the selection group. The order in which you define the three points is important because it determines the relationship between the two planes. The order must be the same for both the from and to planes.

Point 1 — location

Point 2 — alignment

Point 3 — direction

The system moves — or copies (depending on the option you choose) — the first defined plane (from-set), together with all the entities of the selection group, to coincide with the second plane (to-set), according to the following rules:

The plane defined by points from set A, 1-2-3 is translated to the plane defined by points to set B, 1-2-3.

Point 1, set B is located at point 1, set A.

Line from points 1-2 of set B is aligned with line 1-2 in set A.

Point 3, set B is relocated in the direction of point 3, set A.

If you choose to move the selection group, the set is moved. You can confirm or reject the result. If you choose to copy the group, the relationship is maintained for each multiple copy.
