PreForm’s performance depends on your computer and the contents of the 3D scene: for example, large, highly-detailed, supported SLA models or densely-packed SLS models can cause PreForm to lag. Additionally, high-resolution models at a low zoom level may have triangles that are less than a pixel in size, using system resources with no actual benefit to your work.

Starting with PreForm version 3.64.0, you can limit the level of detail that remains visible while you interact with PreForm. Your chosen settings become visible when moving the camera, highlighting models, and during other interactions with the 3D scene.

To change your rendering and level of detail preferences:

As noted above, the lower the Dynamic Detail Level setting, the greater the allowable deviation from the original model during interactions with the 3D scene.

In the example below, a gyroid lattice has been scaled to fill the Form 4L build volume. In this case, when the Dynamic Detail Level is set to Low, the level of detail on the lattice surface drops as the camera rotates or zooms in and out. When the interaction stops, the model returns to its original level of detail. Depending on the model and setting, the model may not visibly change: here, when the Dynamic Detail Level is set to Max, the level of detail on the lattice surface does not change as the camera rotates or zooms in and out.
