Change the default Surface Deviation from .5 to .05. This will create more polygons from the CAD solid geometry by increasing the tessellation. This increase of polygons will make the 3D model look better, but will require an extra step of optimization which will be covered later. Click > OK.
Right Click in Viewport and Select > Select All. The Viewport is the area shown above with the four images.
Right Click in the Menu Area and Select > CAD Tools.
Select the Reduce Model Icon from CAD Tools menu.
Click > Process from the Reduce Model Dialogue Box.
Notice that the current 3D scene has 39,190 triangles/polygons. The function of this tool is to reduce the amount of polygons down as low as possible, but retain the visual fidelity of the model. This process will optimize the 3D file to be as small as possible inside the PDF similar to setting the pixel resolution of a 2D raster image.
OK, so you want to stamp your document. Maybe you need to give reviewers some advice about the document's status or sensitivity. This tip from author Ted Padova demonstrates how to add stamps with the Stamp Tool along with related comments.
