Command Overview

Wireframe Linking Settings provide access to a 3D Solid linking method.

The link-3dsolid-method-switch command enables this option.

This method uses a proprietary linking algorithm that is particularly effective in the creation of bifurcated wireframes without the need for additional tag (guide) strings (other than, optionally, virtual ones), using the link-multiple-strings command - which can, in many cases, resolve the infamous trouser leg problem inherent to the design of underground development CAD data.

Note: if the 3D Solid linking method is enabled, the Optimal Linking string linking option is not available.
