Shorten the Plot Scales List in a Viewport
From: AutoCAD Productivity Articles #140
Originally published: June 2015
If you plot from a viewport on a Layout tab, and you have a specific collection of plot scales you typically use, you may be interested in editing that list to display only the ones you need to see.
There are other approaches to accessing the same plot scale regularly, but this is one of the most straightforward.
How to Modify the List of Plot Scales
When you're in a viewport, click the location on the Status bar where you see the scale/factor for the current viewport.
Scroll to the bottom, then click Custom… to open the Edit Drawing Scales dialog box.
I would recommend keeping 1:1, but then select those plot scales you really don't need, then click Delete.
Organize the ones you use all the time by using Move Up or Move Down.

Note: If you totally gom it up, you can always hit Reset, then choose your desired collection of either Imperial, Metric, or both.

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.
