FredoGhost is a Proxy framework for Sketchup: By ‘proxy framework’, I mean the capability to temporarily replace an object by another one, the proxy, and switch back and forth between the original version (REAL) and the proxy version (GHOST).

FredoGhost can be used for 2 main purposes

  • Combine different rendering styles in the same view, for instance, some objects in X-Ray, while others staying natural (like in my old plugin XRaySelection). FredoGhost gives you control of the style and of the objects you want to modify.
  • Make your model lighter to work with, since you can substitute proxies with lighter geometry (including just its bounding box) instead of the finished objects. You have some methods to help in that, in particular the 'Proxy' method and the concept of frozen ghosts.

FredoGhost allows to select the objects you want to ghost and to convert them individually to their ghost and Real versions. The ghost methods provided can be parameterized at will. It can also associate a particular ghosting state to a Scene, which can be useful both for individual rendering and a faster working environment.

All commands can be accessed from the FredoGhost Studio dialog box, which exists in 2 forms: basic features and advanced features.

Note that FredoGhost only works with SU2017 and above.

IMPORTANT: For a period, it is advised to make a safe copy of your model, as there might be bugslats or other issues. This will ensure that you keep the main objects of your model in their real form.
