AutoCAD Productivity
Use the INSERT Osnap on Blocks
From: AutoCAD Productivity Articles #134
Originally published: June 2014

In Michael's Corner February 2013 I covered the use of the Insert object snap for text. It also happens to be the Osnap you can use for Blocks.
When you need to snap to the insertion point of a block, I don't bother to set it as an Osnap since it's such a seldom-used feature. When the time comes, simply Shift + Right-click to display the Osnap shortcut menu, then click Insert or use the ‘INS’ keyboard shortcut.

Michael's Corner
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
Absolute and Relative Coordinates
| Coordinate | Interpretation |
|---|---|
| 25,75 | depends on context |
| @25,75 | relative |
| #25,75 | absolute |
It used to be very simple. Enter a coordinate and AutoCAD interpreted it as an absolute coordinate. Enter a coordinate preceded by "@" (the at sign) and AutoCAD interpreted it as a relative coordinate. This simple rule changed when dynamic input was introduced and now the interpretation of coordinates is contextual. For example, when you draw a rectangle using RECTANG, the coordinate for the second point is interpreted as absolute with dynamic input turned off and as relative with dynamic input turned on. Really, try it and see.
Fortunately, there's a new coordinate prefix that forces an absolute coordinate, even when AutoCAD decides you want a relative one. Precede any coordinate with "#" (the hash sign) to force an absolute coordinate.
