Part Offset

Description
The Part 3D Offset tool creates parallel copies of a selected shape at a certain distance from the base shape, giving a new object.

Usage

 * 1) Select the Object you want to create the offset from.
 * 2) Press the  button
 * 3) Adjust distance and parameters depending on the original object and the resulting objects validity.


 * Note: App Link objects linked to the proper object types and App Part containers with the proper visible objects inside may also be used as source objects for offsetting.

Properties

 * : Distance to offset the faces of the shape
 * : Mode of creation . Skin creates a new shape around the source shape. Pipe ( todo ) . RectoVerso ( todo )
 * : How the new corners are build up. Intersection gives sharp corners by linear extension of the edges. Arc and Tangent give rounded corners.


 * 1) Option ː Intersection ː  Allows offsets pointing inwards to "overflood" the gap by intersecting the resulting shape until opposite faces are reached.
 * 2) Option ː Self Intersection ː ( todo )
 * 3) Option ː Fill Offset ː When the shape was 2 dimensional, the gap inbetween the 2 shapes gets filled. The fill is now a solid, hence the source shape is not a solid . Thus boolean operations may lead to strange results. (see example below).

Examples
Object with small offset and rounded ( arc ) corners.

→

Same object with sharp ( intersection ) corners.



Same object with thick distance overfilling the front left gap and allowed intersections.



Arbitrary shape ( draft poly as wire ) with a 3D Offset ( ignores MODE param )



same shape with a 3D Offset as SKIN and filled offset



filled offset with 2 Cylinders creating boolean cuts. Cylinder A goes through the FILL whilst Cylinder B only goes thru the FILL and NOT through the source 2D shape.
