This message means that the created model is too big to be displayed in the solid/sweet mode in a 3D view. The number of triangles that is possible to display in the solid/sweet mode depends on video memory of your GPU. Limitations are as follows:
- 8 million triangles for 1GB VRAM,
- 16 million triangles for 2GB VRAM,
- 31 million triangles for 4GB VRAM,
- 40 million triangles for 6+GB VRAM.
The upper limit is 40M triangles regardless of the GPU you have. However, this is just a display issue. If you exceed the limits above, only a point cloud will be displayed, while the render mode will be preserved.
In this case you can also use a clipping box to display your model by parts. It does not decimate or cut the model, it only displays the triangles inside. You can find more information on how to use the clipping box in the application Help – tile Clipping Box.
