Add surfaces to part faces and pour object faces
You can add surfaces to the faces of parts and pour objects in the model. You can add surfaces to any face geometry, for example curved faces. You can use surfaces for calculating surface areas, such as formwork areas, or for defining face-specific concrete covers for rebar sets.
Each surface is added to a single flat or curved face. Surfaces do not extend over fillet edges between flat and curved faces.
Surfaces are associated with the objects they are attached to. Surfaces cannot exist as standalone objects. A surface can be associated either with a cast-in-place part or a pour object, but not with both. Surfaces associated with parts or pours can be shown in reports as belonging to those objects.
If you modify the geometry of the associated part, the surface will adapt to the changes. If you delete or move the associated part, the surface will follow. If you copy an object that has a surface, the surface will not be copied. If a surface is added to a pour object, it will not automatically adapt to changes that only affect the pour object, such as inserting pour breaks.
Limitations:
-
Surfaces do not recognize faces created by displaying objects with high accuracy, such as curved profile fillets.
-
Surfaces do not have handles, so their geometry cannot be modified separately from the associated object.
-
Surfaces cannot be copied.
-
Surfaces cannot be moved or rotated without the associated object.
-
Surfaces are not shown in drawings.
