Var (Extrusion)
Var 0%. Var 60%.
Varies the height of the extrusion. The value you enter is subtracted from 100% to give the start of the
variation range. This option only has an effect if Preserve Groups (see below) is enabled.
0% - No deviation from the Extrusion value.
60% - All selected polygons are beveled between 40% and 100% of the
Extrusion value.
100% - All selected polygons are beveled between 0% and 100% of the
Extrusion value.
180% - All selected polygons are beveled between -80% and 100% of the
Extrusion value.
Inner Offset
The value entered for Inner Offset plays an important role when interactively beveling with the
mouse. In this case there are no absolute values, so they then indicate values relative to each other.
For example, if you set Extrusion to 1 and Inner Offset to 5, each element is moved exactly ve units
inward for each unit of outward movement, and vice versa.
Denes the internal extrusion — the length the edges of the surfaces are to be inwardly shifted.
Proceed with caution when beveling several connected polygons that you want to keep as a group.
In the following example, only the outer edges of the selection are inwardly shifted. The edges of the
inner surfaces of the selection are not affected.
Before the
beveling.
After the beveling — only
the outer edges have
been shifted.
This can lead to problems when starting from a certain Inner Offset value, since the outer edges can
possibly overlap the internal ones.
