Modify 3D Solids
After creating a 3D solid model, you can use the ShapeManager modeler in
AutoCAD LT to change the form and appearance of the model.
Overview of Modifying 3D Solids
After creating a solid model, you can change its appearance by filleting,
chamfering, sectioning, slicing, and separating.
You can also edit faces and edges on your solid model. You can easily remove
blends created by FILLET or CHAMFER. You can change the color or copy a face
or edge of a solid as a body, region, line, arc, circle, ellipse, or spline object.
Imprinting geometry on existing solids creates new faces or merges redun-
dant faces. Offsetting changes the faces relative to the original faces on the
solid model, for example, making the diameter of a hole larger or smaller.
Separating disjointed composite solids creates 3D solid objects. Shelling
creates thin walls with a specified thickness.
Fillet and Chamfer 3D Solids
With FILLET, you can add rounds and fillets to selected objects. The default
method is specifying the fillet radius and then selecting the edges to fillet.
Other methods specify individual measurements for each filleted edge and
fillet a tangential series of edges.
CHAMFER bevels the edges along the adjoining faces of a solid.
To fillet a solid object
1 From the Modify menu, choose Fillet.
2 Select the edge of the solid to fillet (1).
3 Specify the fillet radius.
4 Select additional edges or press
ENTER to fillet.
