True cross section shapes in a slab can be quite irregular due to slab steps and other forming or architectural considerations. While it is generally advised to model the geometry of the concrete as per the form in the constructed building, it is not advised to always use the true geometry in design. It is often better to modify cross sections considering both their own shape and that of the nearby concrete.

RAM Concept offers two types of cross section trimming: Single Cross Section Trimming and Inter Cross Section Slope Limits.

Single Cross Section Trimming considers one cross-section at a time and modifies the cross-section based on the user-specified trimming type.

Inter Cross Section Slope Limits trims the top and/or bottom of cross-sections based on the adjacent cross-sections, their elevations, and the distance between the cross-sections.

Inter Cross Section Slope Limit trimming always occurs after Single Cross Section Trimming.
