Offset

Offset feature translates each point of the Shape along a local normal by the given Offset distance (signed number, negative value means inner offset).

To create an Offset in the active part:

  1. select in the Main Menu Features - > Offset item or

  2. click offset.icon Offset button in the toolbar

Two Offset algorithms are:

../_images/offset3D.png

offset the whole shape by the same value

../_images/offset3D_partial.png

offset selected faces by the given value, other faces by zero.

Offset the whole shape by the same value

Input fields:

  • Shape defines the base shape (solid, shell or face) selected in 3D OCC viewer or object browser;

  • Distance defines the offset value. Negative value meaning inner offset;

  • Join by pipes check box defines the mode of filling the gaps between translated adjacent surfaces:

    • if <b>Join by pipes</b> is activated, they are filled with pipes;

    • else the surfaces are extended and intersected, so that sharp edges are preserved;

TUI Command:

model.addOffset(Part_doc, shape, dist, isPipeJoint)
Parameters:

  • part – The current part object.

  • object – A shape in format model.selection(TYPE, shape).

  • real – Offset distance value.

  • boolean – Join by pipes/intersection flag.

Returns:

Created object.

Result

Result of offset of a box. Join by pipes activated.

Offset selected faces by the given value, other faces by zero

../_images/offsetPartialPropertyPanel.png

Partial Offset property panel

Input fields:

  • Shape defines the base shape (solid, shell or face) selected in 3D OCC viewer or object browser;

  • Distance defines the offset value. Negative value meaning inner offset;

  • Faces to offset defines the faces of the base shape, which should be offset;

Note: In Partial Offset mode gaps are always filled by intersection.

TUI Command:

model.addOffsetPartial(Part_doc, shape, dist, faces)
Parameters:

  • part – The current part object.

  • object – A shape in format model.selection(TYPE, shape).

  • real – Offset distance value.

  • objects – Faces of the shape in format [model.selection(TYPE, shape), …].

Returns:

Created object.

Result

Result of partial offset of a box. Top and front faces selected.
