Tekla Structures 2016 now includes a new model object type surface for modeling surfaces.
To create surfaces in a model, go to the Edit tab and click Surfaces > Add surface to face:
Then select the part face or pour object face to which you want to add the surface.
Surfaces can be used for calculating surface areas, such as formwork areas or painted areas quantities.
Surfaces have zero thickness, have no handles and are not visible in drawings.
For more detailed information about using the existing surfaces, click here.
You can add surfaces to the faces of parts and pour objects. Surfaces cannot exist as standalone objects. You can add surfaces to any face geometry, for example curved faces. This was not previously possible by using surface treatment. Surfaces are associated with the objects they are attached to. 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.
You can show and hide surfaces by using the Surface treatment and surfaces check box in the Display dialog box.
When you want to select surfaces, use the Select surface treatments and surfaces selection switch in the Selecting toolbar.
You can also use the category Surface in selection filters:
The Create holes option controls whether a surface object is cut with holes or not. Holes can be made by cutting or by connecting parts, as shown in the example below.
A concrete slab includes a rectangular recess as a result of a continuous column:
If case the option Create holes is set to Yes, the recess is also created in the surface, the geometry of the surface is associated to the attached slab.
The following example shows several foundation beams in which the Cast unit type is set to Cast in Place and the model view representation is set to Pours (via Concrete > Pour view):
The option Create holes results in the following:
Surfaces in reports and templates
You can also use surfaces in reports and templates by using the new content type SURFACE in the Template Editor:
