Part Offset

-->

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

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

Properties

 * 1) Offset    :  Distance to offset the faces of the shape
 * 2) Mode      :  Mode of creation . Skin creates a new shape around the source shape. Pipe ( todo ) . RectoVerso ( todo )
 * 3) Join type :  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 exapmple ).

Example
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.
