In my copious "free time" I promised myself to look into material mapping. Well, push came to shove and I needed to get on the learning curve and figure this out, so that's what's front and center this month. My friend Lee Ambrosius [www.hyperpics.com] has authored the "AutoCAD 2008 3D Modeling Workbook for Dummies", just in case any of you want to take what you see here and continue your own learning curve.
The remaining articles are things I had in my "To Cover" list and in my recent training sessions, customers have bumped into some things that I needed to clarify… so hopefully the coverage on Copy with Basepoint, Otrack, and a really cool trick to run 3D Orbit will bring joy to some faces. Which is the point of this whole exercise.
If you would like to contact me directly, you can do that also.
Blessings to one and all,
Recently I had the opportunity to do some training for Standard Textile in Cincinnati, OH, and since they have this great site where you can download fabric swatches in JPG format, I thought it would be helpful to understand the fundamentals of adding textures to 3D objects.
The main player will be the Materials palette. You will need to have a drawing with a 3D object in it in order to go thru this exercise. The process will work on a 3D Face, but you may also want to take a look at my coverage of 3D Orbit in February 2006, or my article on the A2007 command Presspull in December 2006. Either one of those will enable you to get to the point of getting some 3D geometry created. Also, if you don't have a swatch to use, click here to download some of the .JPG files like the one I am using in this exercise.
That should keep you busy during your lunch hours for the next week or so…
This has been around for awhile, but just in case anyone missed it, here's how to copy objects easily from Drawing A into Drawing B… and specify a basepoint on the objects being copied.
Before You Begin… This procedure requires that the variable PICKFIRST be set to 1. Every now and then when folks try this and can't make it work, I find that their Pickfirst variable was set to 0.
Also… If you are in the habit of clicking the Minimize button for a drawing, the "tiling" of the drawings cannot take place. Maximize the drawing, then try CTRL + TAB to cycle between open drawings!again. Then stop using that Minimize button and try that handy process of
And Finally… Your Right-click Customization,needs to have the right-click setting for the Edit Mode set to Shortcut Menu.
Where do they come up with this stuff? If any of you knew about this, I'm late to the party, but I was very jazzed to learn about this and I wanted to pass it along. So there I am, doing some AutoCAD training at a Herman Miller dealer in Michigan, when my good friend Beth says, "Hey, check this out!"
If you have your normal wheel-mouse that's set to zooming when you scroll it, and panning when you push it down like a button, here's what she found: Hold down the Shift key, then push the wheel down like it was a button… and drag it like you're panning.
Presto! 3D Orbit!
Ah yes. To put things back the way they were before you started that, use.
For those of you that were on the drafting board of years gone by, you will recall non-photo blue lead. We used that to essentially "track" points from different locations on the drawing, then where the lines intersected, we'd get out, say, our circle template and draw circles at those intersections. With that said, let's take a look at the Object Snap Track feature.
In this exercise (using the Db_samp.DWG found in the AutoCAD ..\Sample folder since about A2002), illustrate how to "acquire" the Endpoints from two existing objects, then place the center of a circle at their intersection.
In the Drafting Settings dialog box, on the Polar Tracking tab (see Michael's Corner, Basics February 2005), there's a check box in the Object Snap Tracking Settings area to "Track using all polar angle settings". In the illustration, you can see how acquiring a point with this setting enabled will track points at a 45 degree angle, too.
What Color Are Your M&Ms? - If you average out the colors in the last umpteen bags of M&Ms you have consumed, you would find the following color percentages. Brown 13% / Yellow 14% / Red 13% / Blue 24% / Orange 20% / Green 16%. Now there's a perfectly good reason to go get a bag if I ever saw one!

However, running a site like CADTutor does cost money and you can help to improve the service and to guarantee its future by donating a small amount. We guess that you probably wouldn't miss $5.00 but it would make all the difference to us.
Note from Michael: I want to thank all of my customers for continuing to retain my training services (some for over two decades!) and let you know your donations do not go to me personally, but to the ongoing maintenance of the CADTutor ship as a whole and to support the yeoman efforts of my friend and CADTutor captain, David Watson, to whom I am grateful for this monthly opportunity to share a few AutoCAD insights.
