Point Clouds Section

Point clouds section is used to select and display a needed part of the cloud(s) in a certain model space viewport with the possibility of subsequent drawing with vectors.

To create a section of any type, first determine the section plane. After the command completes, the specified plane will be aligned with the screen plane in the resulting viewport. The UCS will also be transferred to this plane, which allows you to draw in this plane.

Just as with clipping operations, as a result of the section commands, the cloud visibility changes only in the target viewport; no changes occur to the object itself. The display of cloud in other viewports remains the same.

Unlike cloud clipping operations, when creating a section, the position of the user coordinate system in the target viewport changes, which greatly simplifies the subsequent “rendering” of the resulting part of the section by constructing vector objects in the UCS plane.
