Part Offset/pt-br

Description

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

Usage

1. Select an object to offset.
2. There are several ways to invoke the command:
   • Press the 3D Offset... button.
   • Select the Part → 3D Offset... option from the menu.
3. An Offset object is created and the Offset task panel opens.
   • Adjust distance and parameters depending on the original object and the resulting objects validity.
4. Press OK to close the task panel.

Notes

• App Link objects linked to the appropriate object types and App Part containers with the appropriate visible objects inside can also be used as source objects. introduced in 0.20
• As noted in the OCC documentation and mentioned in the Properties section, some options are not implemented yet.

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 Wire) with a 3D Offset (ignores MODE parameter).

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 through the FILL and NOT through the source 2D shape.

Properties

Offset

• DadosSource: Source shape.
• DadosValue: Distance to offset the faces of the source shape.
• DadosMode: Mode of creation. Only the Skin mode is currently implemented in OCC so the other two modes have no effect.
• DadosJoin: How the new corners are build up. Intersection gives sharp corners by linear extension of the edges. Arc and Tangent give rounded corners.

• DadosIntersection: Allows offsets pointing inwards to "overflow" the gap by intersecting the resulting shape until opposite faces are reached.
• DadosSelf Intersection: Not yet implemented in OCC and thus should be left with the default value (false).
• DadosFill Offset: When the shape was 2 dimensional, the gap between 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 above).
