Original Dimension Value

by Michael Beall

From: AutoCAD Productivity Articles #143
Originally published: December 2015

Since the dimension text of an associative dimension is Mtext, double-click anywhere on an associative dimension and you can add additional information… or modify the value to what you want.

Dimension 1

But what if you want to put the dimension back to the original value?

Insights:
If you reposition an extension line origin grip of a dimension and the value doesn't change, the original value was modified.

If you double-click a dimension and the edit box has a white background — not blue — the original value was modified.

Dimension 2

Solution:
Double-click the dimension, then put the less-than and greater-than characters in the dimension box, like this… <>

The original value will be restored.

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.

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.
