Custom planes

Module(s): General: Roofs, Planes, Sections

You use Custom Planes to define local pairs of reference planes. These planes (there are always two: the upper plane and the lower plane) can be inclined at any angle and have the height that you assign to them. Custom reference planes have priority over the default reference planes.

To define custom planes, enter three points or specify two points and the angle of inclination. A distinction is made between between definition points and construction points:

• Definition points specify the position and orientation of the pair of reference planes.
• Construction points define the outline and extents in plan.
  
  As you can see, entering custom planes involves two steps. This is very useful when you want to take the height values from existing points and planes but define other boundaries for the pair of custom planes.
• When entering horizontal parallel custom planes, you do not need to differentiate between definition points and construction points as they are identical.

Note: In the Options - Planes page - Roof planes, custom reference planes area - Default setting, you can specify whether custom planes are displayed with fixed format properties. Otherwise, the settings on the Format toolbar are used.

What do you want to do?

Enter a pair of custom reference planes consisting of parallel horizontal planes

Enter a pair of custom reference planes consisting of parallel inclined planes

Enter a pair of custom reference planes consisting of two inclined planes

Additional tools for creating planes:

• Roof Frame
• 3D to Planes

Note: The following tool only applies to pairs of reference planes created using the Custom Planes tool:
Modify Planes (How).

Activate Modify Planes in one of the following ways

• Menu bar: Modify Architecture General: Roofs, Planes, Sections

• Palette: Tools Modify area in the following module(s):

General: Roofs, Planes, Sections

Note: You can use the Modify Roof Frame tool to modify planes created with Roof Frame.
