T-FLEX Parametric CAD. Fundamentals. 2D Design

Offset Curves
The offset distance can be entered in the “Offset” input box of the
element parameters dialog. Positive offset values correspond to outer
positions of the offset curve with respect to the reference element,
while the negative – to inner positions, respectively. In the case of
using the mouse input in offset creation, the parameters dialog is
not displayed, and the value of the “Offset” parameter is derived from
the cursor position. The offset curve is created on the side of the
reference object pointed to by the cursor.
Offset position can also be defined using an existing node. To do this, select the reference element for the
offset curve. This brings the following option in the automenu:
Select Node
Use this option for selecting a node the offset curve will be passing through.
To reject a reference element selection, use the option
S
Cancel selection
Offsets can be constructed to composite objects made of various-type entities, such as a
spline and a line. To do this, first create a 2D path along the desired contour, and then
use the path for offsetting. The corners of the reference curve become rounded on the
offset curve, as rounding is adopted for handling offset corners in T-FLEX CAD.
When a spline offset is generated, self-intersection loops may occur in the offset
contour. The offset parameters dialog box provides the option for loops stripping.
