- Create a wire with following the counter-clockwise direction and select it.
- Press the Arch Roof button, or press R then F keys
- The default roof object could have a strange shape, it's because the tool is missing some necessary information.
- After creating the default roof, double click on the object in the tree view to access and edit all the properties. Angle must be between 0 and 90.
- Each line corresponds to a roof pane. So you can set the properties you want for each roof pane.
- To help you, you can set
Angle
or Run
to 0
and define a Relative Id
, this makes an automatic calculation to find the data relative to the Relative Id
.
- It works like this:
- If
Angle = 0
and Run = 0
then profile is identical to the relative profile.
- If
Angle = 0
then Angle
is calculated so that the height is the same one as the relative profile.
- If
Run = 0
then Run
is calculated so that the height is the same one as the relative profile.
- Finally, set an Angle to 90° to make a gable.
