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

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

Properties

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

Option ː Intersection ː Allows offsets pointing inwards to "overflood" the gap by intersecting the resulting shape until opposite faces are reached.
Option ː Self Intersection ː ( todo )
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) .

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.
