Tutorials

CADTutor tutorials are all original and specifically designed to get you working with AutoCAD and other applications as knowledgeably as possible. We don't believe in providing only quick step-by-step tutorials like other sites. Our tutorials are comprehensive and aim to give you a deeper understanding and a better learning experience. See the AutoCAD tutorials page for more information.

Tip of the Day

Using Imprint to sub-divide faces

The Imprint command (ModifySolid EditingImprint Edges) gives the first impression of nothing more than adding graffiti to solids. Upon closer investigation, however, we find that it actually modifies the face on which it is placed, effectively sub-dividing it. Sub-divided faces can then be extruded using the Extrude faces command (ModifySolid EditingExtrude faces).

Procedure

1. Create a box.
2. Draw a line on one of the faces.
3. Imprint that line on the solid.
4. Use Extrude faces to extrude the sub-divided face.

To generate this modified part with Boolean operations would not be difficult but, as we all know, speed and accuracy are the name of the game. The procedure describe above can be auto-executed with the command macro:

^C^C_line;\\;_solidedit;b;i;\last;y;;;f;E;\;\\;;

The UI could benefit from some advanced programming, but if one pays attention to the Command Prompts, it's not so bad.

Note: This tip relates to versions of AutoCAD before 2007. Although the technique works with 2007 and above, the same operation can be achieved more easily using the Presspull tool.
