To apply structural and analytical attributes

You can apply Structural as well as Analytical attributes to a slab, free, or linear form.

Note: Ensure the

( Analytical Features ) is turned on, to display also the Analytical tab.

Select ( Apply Structural Attributes). Opens the Apply Structural Attributes to Slab/Free/Linear form dialog.
Complete the fields as required. You do not have to enter any information to apply structural data. If you are applying analytical data, review your analytical settings, especially the Stroking Tolerance setting if the form is curved.
In the model, select the slab, free, or linear form to which you want to apply structural data, and accept. If the Analytical tab is present, you are also applying analytical data.
