Michael's Corner is a monthly publication written by Michael E. Beall, Autodesk Authorized Author and peripatetic AutoCAD trainer. Michael travels all over the USA, bringing his fantastic experience and great understanding of AutoCAD to his clients. Michael's Corner brings together many of the tips, tricks and methods developed during these training sessions for the benefit of all users.
Michael's Corner provides something for every AutoCAD user. Every month, a number of articles cover a wide range of topics, suitable for users at all levels, including "The Basics" for those just starting out. Essentially, the aim of Michael's Corner is to help all AutoCAD users work smarter and faster.
It's a God-thing.
I had no idea that 14 years ago I would be given the opportunity to make an impact on the professional lives of so many. Only God knew what was ahead, and hopefully, the contributions I have made through Michael's Corner have equipped many of you to be more productive and a bit more savvy using AutoCAD. And apart from all the AutoCAD bashing that is going on, I'm sure it has a long life ahead.
So, in an effort to keep the AutoCAD fires burning, here's what I have for my final installment…
…A reminder on how to customize your hot keys
…Three Power Tools — one for Zoom, one for editing, and one for Layers
…Two Odd Spots — one for Layers and one for Hatching
…Buried text treasure
…And how to Search 14 years of the Archives
As for what's ahead for me, I will continue to present a variety of AutoCAD sessions — Fundamentals, Intermediate, Customizing, Updates, and 2D & 3D. I will also keep training CAP Designer, 20-20 Worksheet, Visual Impression (those three from 20-20 Technologies, Inc.), and some Revit Fundamentals. Next year I'm looking forward to being very involved in training CET (from Configura, Inc.) when Herman Miller joins the growing number of manufacturers embracing this software that is being touted as the ‘Future of Space Planning’. Personally, I'm looking forward to spending a bit more time with Donna, my lovely bride of 30 years. When this posts, we'll probably be within days of going on our 30th Anniversary vacation to the Tanque Verde Ranch in Tucson; Ee-Hah! We had such a good time when we went for our 20th, we figured we'd do it again!
Ah, and I'm hoping to have The AutoCAD Workbench, Final Edition out before snow flies.
And with that, Mike drop! …so to speak.
The LORD bless you and keep you;
The LORD make His face shine upon you,
And be gracious to you;
The LORD lift up His countenance upon you,
And give you peace. Numbers 6:24-26
The Join command slid in under the collective radar a couple versions ago, and is really a handy tool to 'heal' walls or other geometry with a gap (or gaps) in the continuity of the linework.
The Join command can only be used to join objects of the same type (line to line, polyline to polyline etc.). I know, bummer. However, you can use Pedit to join polylines to other polylines, lines and arcs. See our lovely video tutorial for details.
You can join any Lines that are colinear, even if there's a gap. Unfortunately, this doesn't work with Polylines - they must be touching end-to-end. However, as above, this can be done with Pedit.
If the lines being joined have different properties, the line selected as the Source object wins.
If you have more than 2 co-linear segments, when prompted to select the Source object, you may use any windowing method to select the geometry. Window/Crossing/CPolygon/WPolygon are valid options.
Yes, you can use the Join command to join 2 arcs that lie in the same circular definition (per the figure shown here).
Note: Since arcs are, technically, created counter-clockwise, to heal the gap in the illustration shown, you would pick the larger arc first. After selecting the second arc, since AutoCAD has to go counter-clockwise to 'see' what you selected, it will join the arcs based on its direction of 'travel'. I know, goofy, but that's how it works. If you pick the smaller arc first, it has to go the long way around to join to the long arc.
Yes, you can 'heal' a gap in a circle by following these prompts:
Command: JOIN
Select source object or multiple objects to join at once: Select the circle
Select objects to join: Press [Enter]
Select arcs to join to source or [cLose]: L [Enter]
Arc converted to a circle.
And finally…
If the lines are not perfectly co-linear - not even a variance of 0.000001 (6 decimals) - Join will pitch a fit and not join the selected lines.
0 objects joined, 2 objects discarded from the operation
If the co-linear condition of the lines is separated by a value of 0.0000001 (7 decimals), the selected geometry will be joined. But other than that, it's a pretty slick little routine.
