Exterior Views, Representation with concealed Edges
You can create exterior views, or a representation that contains no concealed edges, with an option in the ‘Properties’ dialog of the cross-section view.
As soon as the dialog is terminated with ‘OK’ the view is recalculated, which can take several minutes depending on the elements contained in the view. For the same reason it is not recommended to have views open with this option, when planning or making modifications to the project. A basic concept of the software is that a view is updated after every change, which can have a considerable negative effect on performance for views without concealed lines.
The effect of this option is shown in the following example; on the left the view without concealed lines, and on the right the normal cross-section view with the same position and depth.
