Every shape will have one or more relations. These relations define how the shape is ‘related’ to the other shapes, to the world coordinate system or to 3D points. Relations control the size, shape, position and orientation. This table lists all the relations types and what parts of the shape they use:

Shape Relation Type |

Based On Entities |
Description |
|
Base |
is placed at origin |
One shape |
The shape sits at 0,0,0 and is aligned with the coordinate axes. |
|
Ground |
lies on ground |
One shape face |
The shape face sits on the ground plane. |
|
Coplanar |
shares same plane as |
Two shape faces |
One shape face is in the same plane as the other face. |
|
Concentric |
is concentric with |
Two shape faces |
The centers of the faces are the same. (requires a coplanar) |
|
Aligned Face |
is aligned with |
Two shape faces |
The two faces have the same rotation. (requires a coplanar) |
|
Same Size Face |
is the same size as |
Two shape faces |
The two faces have the same dimensions. (requires a coplanar) |
|
Colinear Edge |
is colinear with |
Two shape edges |
The two shape edges are colinear (both edges lie on the same infinite 3D line) |
|
Same Shape Rotation |
is the same rotation as |
Two shapes |
The two shapes have the same Rx,Ry,Rz rotation. |
|
Same Size Shape |
is the same size as |
Two shapes |
The two shapes have the same sizes. Shapes must have matching parameters. |
|
Parameter Equals |
is equal to |
Two shape parameters, or a shape parameter and a constant |
The two parameters are made equal or the parameter is made equal to a constant. |
|
Points Base |
is aligned by 3D points |
Shape vertices and 3D points |
The shape is solved so that the tied vertices line up with the 3D points as best as possible. |
