Drawing Information
From: AutoCAD Productivity Articles #137
Originally published: December 2014
For billing purposes, it's nice to know how long you have spent working in a drawing. To that end, the Time command may be a helpful resource, especially given the elapsed time feature that can be toggled ON and OFF, and can also be Reset.
Command: TIME Current time: Sunday, November 23, 2014 3:44:54:790 PM Times for this drawing: Created: Wednesday, November 14, 2007 2:42:44:984 PM Last updated: Sunday, November 23, 2014 9:59:28:105 AM Total editing time: 0 days 04:45:06:399 Elapsed timer (off): 0 days 04:44:32:866 Next automatic save in: 0 days 00:07:30:395 Enter option [Display/ON/OFF/Reset]:
To keep track of your time in the drawing, launch the Time command, then begin the elapsed timer with the ON option. When finished, use the OFF option to display the total editing time. The above information indicates that I was editing the drawing for a little more than 30 seconds - 04:44:32 to 04:45:06.
DWGPROPS [] Another useful tool for quick information may be the Dwgprops command found in the ‘scarlet letter’. It's nice to have the Location and Size information immediately available, rather than going out to Save As.

Tip of the Day
Using Imprint to sub-divide faces
The Imprint command () 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 ().
Procedure
- Create a box.
- Draw a line on one of the faces.
- Imprint that line on the solid.
- 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.
