Michael’s Corner - December/January 2015

Making it Happen at Autodesk University 2014!

Yet another year has flown by at CADTutor and I'd like to thank Michael for another excellent year of tips, tricks and general AutoCAD wisdom—if you've managed to get tickets for one of Michael's sessions at Autodesk University, you're in for a treat. I'd also like to thank you, our loyal readers and supporters. CADTutor only exists because you keep coming back to the site, and as long as that continues, so will the site.

This month's Corner is a Christmas variety box (whatever happened to them?) of treats. The main article provides a technique for the automation of viewport scales, something which many of you will find genuinely useful. Other articles cover pan and zoom tricks, how to make life easier when your drawing ‘disappears’ after Zoom Extents and a reminder about drawing time and drawing properties—an often forgotten resource.

Have a great festive holiday and New Year celebrations and here's looking forward to an even better year in 2015. We'll be back early in February with more AutoCAD tips and tricks.

Video Tutorials

We've added a new Video Tutorials section to CADTutor! Some of our users have asked for video tutorials in addition to the text-based tutorials already on the site. Check them out and let us know what you think. Also, for those of you who prefer to watch your online video at YouTube, why not visit the CADTutor YouTube channel?

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.
