The Imprint function in Autocad 3D is a great way to add a new face to an existing object, or for adding a different material to a part of an object. We show you how in our Autocad 3D training courses.
The imprint command adds 2d geometry to 3d objects, thus creating extra faces. For example, first create a cube using the Rectangle tool and selecting C for cube. Then enter in one edge length, for example 200mm, and the cube will be created.
The Imprint function requires some 2d geometry on one of its faces, so draw a circle on top using the Circle tool, or by entering C into the bottom Command line, together with a centre point (this could be one corner as shown here) and  a radius value, for example 100mm.
Next go to the Home tab and choose the Imprint tool from the Solid Editing tab. If you are using a version of Autocad prior to the 2009 release go to the Modify drop-down menu, and select Solid Editing and Imprint. Then first select the cube and next the circle, and hit Enter to complete the command. Autocad asks whether you wish to delete the source object, that is the original circle: choose Y for yes, and hit Enter to accept, and Enter again to exit the command. We now have the new face on the top face of the cube.
To create a projected face as shown here, go to Solid Editing and the Extrude Faces command. Then select the new quadrant face and enter an extrusion height, for example 50mm. Autocad also asks you for an angle of taper: type in 10 degrees, for example, and the resultant object is shown above.
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: www.autodesk.com. Support options and user forums are also available from the home page.
