If you are on the market for a software solution capable of handling the unfolded section of a set of entities such as 3DSOLID, 3DMESH or 3DFACE, taking DEVELOPED SECTION for AutoCAD or BricsCAD for a spin could provide you with several benefits.

First of all, it need be mentioned that the utility is an add-on for both AUTOCAD 2002-2018 and BricsCAD v16-17 that can, aside from determining the values of the aforementioned entities, also handle vertical plans passing through a 2D POLYLINE.

It is also worth bringing into discussion the fact that this 2D POLYLINE may integrate arcs into an XOY plane, with the intersection of the vertical plane and the first segment of POLYLINE resulting into a developed section in the form of 3DPOLY entities.

As for the applicability of such a software utility, it must be pointed out that checking the gauge underneath a passage can be done when you decide not to carry out the unfolding process.

Based on user-specified dimensions, two viewports for printing are created, with the first one comprising the initial view whereas the other one includes the section itself, but in an unwrapped plan.

Aside from that, setting the concatenation precision of the segments building the intersection is an option for users resorting to DEVELOPED SECTION for AutoCAD or BricsCAD.
