2010 AUTOCAD TIPS AutoCAD Free Form Design Surface Modeling using the AutoCAD's 2010 freeform modeling tools are designed to sculpt different mesh into complex forms by pushing and pulling its various faces, edges, and vertices to create smooth and rounded model surfaces for better visualization. Meshed object can then be converted into solids and modeled using AutoCAD’s regular solid modeling tools. With free-form design tools, almost any shape can be created. AutoCAD’s toolset for mesh modeling comes closest to actually working like with clay and create a free-form “organic” shape. It includes tools to carve the shape, stretch it and mold it in coarse and fine details. Mesh objects are made up of tessellated objects. Tessellated objects are faces bounded by edges. With free-form modeling tools, faces, edges, and vertices of tessellated objects can be moved, scaled, stretched, pushed, pulled, and rotated individually using the GIZMO or other tools to create smooth and rounded objects.
Figure 1 Free form stick-shift shaped from mesh cylinder primitive using default tessellation and then moving or stretching individual faces to create the final stick-shift shape. Filters can be set to easily select the faces, edges, or vertices to be modified and movements can be confined to specific directions to make shaping easier. Smoothing tools provide options to smoothen specific surfaces or the entire object in one step. Faces can also be selected for un-smoothening.
Figure 2 Faces maybe selected one at a time or in groups and then moved or scaled to create the desired shape. For more detailed objects, the density of the tessellation can be increased. Check out the GIZMO section to learn how the different tools are applied to mesh objects, faces, or edges to shape the model.
