AutoCAD Productivity

Rotate with the Copy Option

From: AutoCAD Productivity Articles #135

Grips don't get a lot of respect, but they are really quite powerful [See ‘The Lost Art of Grips’ in Michael's Corner March 2005], and the introduction of multifunction grips a few versions ago [Covered in Michael's Corner in July 2011 & April 2012], really kicked 'em up a notch.

However, what I want to mention here, is the Copy option of the Rotate command (…which is a similar feature when using grips, if you were wondering about the relevance).

Chairs to copy and rotate

In the following exercise, the chair arrangement must be completed on all four sides.

How to Copy with Rotate

  1. Launch the Rotate command, select the objects to rotate, then press [Enter].

  2. To pick the middle of the conference table, Shift + Right-click and click Mid Between 2 Points, then click two diagonally opposed corners to specify the rotation basepoint between them.

  3. Click the Copy option (or enter C if you have a version prior to AutoCAD 2013).

  4. Turn on Ortho if necessary, then click to rotate—and copy—the selected objects!

Between 2003 and 2016, Michael Beall (and one or two guests) wrote almost 600 articles for CADTutor. The focus of these articles is AutoCAD productivity, and although some of them are now more than a few years old, most remain relevant to current versions of AutoCAD. The article above is just one example. Check out Michael's Corner for a full listing.

Tip of the Day

Using Imprint to sub-divide faces

Imprint in actionThe Imprint command (Modify ❯ Solid Editing ❯ Imprint 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 (Modify ❯ Solid Editing ❯ Extrude 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.
