Duct choiceYou can lay out a distribution route (tubes or channels)

Select the command “Distribution layout” and click inside the location plan at the initial point of the distribution layout. A dialogue box enables:

• setting the initial height above ground and the width;

• choosing the tube/sheath etc.;• adding new lines already

defined or create new ones as required.
