Thank you for the Good Wishes
 
Thank you to all those who emailed me wishes for a speedy recovery. I have a new respect for my collarbone...nothing like breaking a bone to make you appreciate when all your parts work properly.
Bay Windows in ADT 2005
 
Beth Powell emailed me about what she considered a bug in ADT when using the bay window. In elevation and isometric views, you will see the opening for the window and the actual window appears offset from the opening.

This occurs when you have failed to define the offset and UCS for your block properly. If you look at last week's tutorial, you see that I discuss this issue. You need to use the Preview window to check that you have used the correct settings. ADT2005 assumes that the block will be inserted at the center of the opening in the X direction, the rear of the block in the Y direction, and at 0 elevation on the Z- axis. Once you understand this, set the UCS for the block at the midpoint of the bottom rear of the window frame. Then for the insertion point of the block, set the X, Y, Z, and offsets accordingly.

Cell Phones Under Attack
 
On Jan 1, a Portland, Oregon company, Qsent, will begin compiling cell phone numbers for a 411 directory system. Only those who want their numbers in the directory will be listed...it is strictly an "opt-in" system. So, you do not have to worry about registering your cell phone or any other phone to the "do not call list". If you do nothing, your cell phone will not be listed in this directory. Most of the cell phone companies are not participating in the 411 directory because they value their customers privacy and don't want to lose customers. You may be asked if you want to be listed in the directory and then you can just say 'no'.

You can add your cell phone to the national "Do not call list". Call 1-888-382-1222 from the cell phone that you wish to have put on the "do not call list" to be put on the list. You may also register on their website for free.

Political parties and some non-profits are exempt from the Do Not Call registry. However, if you get a call from someone you don't want calling you, request in a civil tone that your number be placed on their "Do Not Call" list and they are required to comply.

Tutorial on Solid Modeling in AutoCAD 2005
 
My apologies...last weeks' link to the tutorial on solid modeling was incomplete. The correct link is below.
And Yet Another XREF Lisp
 
Beau Goff, of Phoenix, Az, emailed a request for a lisp routine that allows him to freeze layers in an xref that have a specific pattern in their name; i.e. AIR.

The following routine prompts the user to select an xref, enter the layer filter pattern - any set of letters or numbers, then freezes all layers in that xref that contain the desired pattern. As always, the code is open with plenty of comments so you can modify it for your own use.

Beau tells me that the routine works great for him and commented that my code is very "simple". I take that as a compliment. I tend to write code like a "Dick and Jane" book, very basic, nothing fancy. Yes, there are coders out there whose code is a lot more advanced, but I have found that the fancy code is a lot harder to maintain and re-use.

Beau also wanted a line of code that would bring up the saveas dialog for him in lisp...

  • (vl-cmdf "_saveas" "" "~")
