FredoSection provides several tools dedicated to section planes:
-
Generation of section cut faces with hatching patterns at scale for section planes which are active in scenes. Patterns can be assigned by Container and/or by Tag

-
Section box: create a configurable set of section planes (inside box, outside box, custom section line) for a selection of geometry.

-
Door and window schedule: create a permanent companion model with selected views of doors and windows, which can then be mapped at scale in a Layout document. This will be released in a next version however.

-
Pattern Manager: This tool is used to create / modify hatching patterns and assign them to groups and components to decorate their cut faces created by the other tools above. FredoSection comes with a set of built-in patterns, but you can create your own.

FredoSection is mainly oriented to support a workflow Sketchup + Layout. It only works on Scenes. The hatching patterns are scaled by scene, so that they always appear at the same size when printed on paper. This requires that you assign a paper scale to each scene processed.

Here is a short user manual for the generation of Cut Faces, the Pattern Editor and the Section Box.
