Michael’s Corner - October/November 2016

One-derful!!!

This month's Corner marks the end of an era. I've been running the CADTutor website for 20 years and for the last 14 of those I've been ably assisted in that endeavour by Michael Beall who has consistently provided content of the highest quality. Michael has written almost 600 articles for CADTutor in close to 150 monthly columns. If Autodesk are listening, they should probably give him a medal for services to AutoCAD. I'm constantly surprised and delighted by how generous people are when sharing information, wisdom and experience on the Web and Michael is a prime example of how Tim Berners-Lee hoped people would share their knowledge. Thank you Michael for all you've done for the CADTutor community.

So, for Michael's final corner we have articles on modifying the action of the F1 key, no less than 3 Power Tool articles, including tips on zooming with your mouse, background hatch colours and text frames for Mtext. As always, these articles are designed to help you work smarter, not harder. I hope you find them useful.

CADTutor itself is staying put and we have a few new things planned for 2017, so stay tuned. And don't forget that all of Michael's Corners are still available at CADTutor for your future reference.

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.
