The Hollowing blockers is a tool that allows the pro users to prevent the hollowing operation in the specified volume, like thin parts or in a zone where a drain hole can’t be added to avoid a resin trap.
Once in the Prepared Workspace with the Hollow Tool active on the left side, you will find a dedicated tool option for the Hollowing Blockers on the right side.
You will need to have a selected model with a 2D/3D hollowing previously applied to be able to add/update the blockers.
Hollowing blocker in action:
When you press Add/Edit you will start the process in a new window.
The application interface will change to display only the tools and options needed to set up Hollowing Blockers.
In the drop-down list, select the most appropriate shape, cylinder, cube, sphere to start protecting your model.
Simply click on the surface to add a primitive and transform it using the gizmo to scale, rotate, translate operations.
Multiple primitives can be added if needed or duplicated using the dedicated button.
You can also delete a blocker using the delete key or the red trash can icon.
Note: Don’t forget that you can use the clipping bar to have a better view of the model inside if needed.
When finished you can update the result to apply the modification, it’s useful with the hollowing 3D. Hollowing 2D is refreshed automatically.
Note: If you exit the modification will be applied automatically.
Lastly, the hollow blockers’ visibility can be toggled between a wireframe view and an invisible state using the Show wireframe on/off switch in the prepare space.
