Autocad 3d surface

by Design Workshop Sydney

Creating mesh surfaces in Autocad 3d is a simple process often used in product design, for example. We show you how in our Autocad 3d coursesautocad-3d-surface
To create a simple Mesh object like the screenshot here first go to the 3d Modeling workspace on the bottom right pop-up menu. Note the Solid, Surface & Mesh tools that appear on the top Ribbon.
Go to Mesh Modeling > Mesh tab > Primitives > and hit the dialog box launch button (the small arrow). Make the following changes: Tessellations (these are the faces): L3 > W3 > H3 > OK. Select the Mesh box tool > set the first point at 0,0 > then punch in 5000 > tab > 3000 > and hit Enter > 2000. Select the box and right-click on it > Smooth More > increase it by hitting Enter twice. Smoothness will be Level 3 – see the tool tip. To reshape hold Control & select two faces – note that the Gizmo axes highlight in yellow > move up by 2000.
Then right-click on the Gizmo > select Rotate > and punch in 45º to add curvature. To remove the smoothness from selected faces (ie. sharp edges), go to the Mesh tab > select the Add Crease tool > Subobject: No filter > click on a face > crease value: 2 > Enter. Now select the Extrude Face tool > select a face > and pull out to extrude – note the sharp edges. Or Subobject > No Filter > select those faces > Crease value: 2. To smooth more select the object > right-click > Refine Mesh to increase level of smoothness (or the Smooth More tool). Note that doing this will tend to slow down the screen refresh. Orbit around the object.
To manipulate individual vertices go to the Wireframe mode (VS > 3), then click the Subobject tab > press No Filter to see the drop-down menu. Note Vertex, Edge, Face > select Vertex. Press CTRL to add to selected vertices > highlight Z-axis > pull in Z direction > punch in value.
To Split Faces choose the Split Mesh Face tool > Subobject: No Filter. Press CTRL and click on a face. Click on two opposite edges and Extrude a face.
The 3d interface in Autocad is user-friendly and easy to learn, and we take time to teach a broad range of applications in our classes including modeling, materials, lighting and animation. See many examples of our clients’ work on our Facebook page. For more information there are lots of resources on the web, but try the Autodesk site to begin with: Support options and user forums are also available from the home page.
