||For rectangular parts, i.e. ducts,
the hole is placed on the Side: Top, Bottom, Left or Right. When placing
a hole on round
parts such as tubes, pipes or round ducts the hole placement surface
parameter is the Orientation Angle.
Tangent Angle is used only with holes placed on round parts. Set this to change
the tangent of the connector for subsequent routing. When set to zero,
the tangent angle will be the same as the orientation angle.
The Inset is the origin of the hole. Making this a positive value, say 1
inch, 'insets' the origin of the hole into the part 1 inch below the surface. A
negative value will raise the origin of the hole above the part surface.
This is parameter used for both round and rectangular parts. (After
'insetting' the hole in the part you will not be able to select it in
the 3D viewer. Click the Edit Part Parameters button and select the hole
from the specifications tree.)
Center Offset is used when placing a hole on a rectangular part. Set
this value to adjust the side-to-side location of the hole.
For rectangular hole parts the hole size is modified using the Height
and Width parameters.
