2.) Component parts:

Selected length

The duct Length is the distance between both picked points in the drawing.

+/-

Field to enter a additive or deductive length value, in order to e.g., select a defined distance from duct to wall.

Rest length

Is the last duct length. (smaller than the standard length)

Standard length

Is the entire length of ductwork for fabrication. This value can be edited.

Entire Length

Creates a duct with the 'duct length'.

Symmetrical

Divides the duct length in equal standard lengths, so no rest length remains.

The calculated standard length is smaller than the normal standard length.

Rest to fitting

The component part is extended from the rest length.

with rest length

rest to component part

Deduct rest length from scan length

Starting length

Deletes any changes made and returns to standard values.
