CADTutor tutorials are all original and specifically designed to get you working with AutoCAD and other applications as knowledgeably as possible. We don't believe in providing only quick step-by-step tutorials like other sites. Our tutorials are comprehensive and aim to give you a deeper understanding and a better learning experience. See the AutoCAD tutorials page for more information.
If you can't see what you're looking for on this page, take a look at the list of all tutorials and don't forget that there's lots more content in the Michael's Corner section of the site.
We're always on the lookout for good content. If you have a tutorial or an article that you'd like to see published on CADTutor, get in touch using the contact form.

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.
