Wblock vs. Purge Essay
Tip Patroller Mitchell Hirschklau read Bill Fane's December 2006 "Learning Curve" column on Wblock and Purge and e-mailed Bill these thoughts, but then thought everyone might benefit from the information:

"I tell my apprentices to remember that when they use Wblock, invisible items are also copied -- items that they really may prefer not to have added to their newly created blocks. Specifically, when you Wblock an object (or a group of objects, text, dims and the like) you are also Wblocking out your current active layer, your current text style and your current Dim style. Your intent may have been to Wblock out objects on Layer 1, as well as Text entities in Text Style ABC on Layer 2, plus a dimension string on Layer 3 (in Dim style 1eq50f that contains dimension text in text style DEF). However, because your active layer, at the time of Wblocking, was Layer 9, our active text style was UVW and your active Dim style was 1-8eq1f that contained text style XYZ, you have added an extra layer, an extra Dim style and two extra text styles to your supposedly pristine wblock.

"I emphasize to my users that a wblock is really a mini drawing. If you want it as clean as possible so that it’s useful for years and on hundreds of projects, then you must be very careful and precise when creating it. Typically you should separately load (and purge, etc.) this file.

"You should also remember that a wblock, despite your selection of a base insertion point in the wblock’s creation, also retains the parent's drawing origin. This is why an insertion of a wblock as an unexploded block in the new drawing might not center on display. The on-screen drawing is centered, it’s just that there's now a block built with an old drawing parent's origin point, which is way out there in left field!

Auto-Numbering with Mtext
Tom Napier reminds users of this handy use of Mtext in AutoCAD 2006 and 2007 using Notepad selected as text editor: "To have Mtext’s autonumbering start with a number other than 1, start a text box, and when the number 1 pops up, press Backspace, type in the number you want to start with (such as "8." -- be sure to include the period), then choose Tab. The notes are then consecutively numbered from the number you entered. You can also renumber previously typed notes by placing the cursor at the beginning of the text of the first note and follow this same procedure. When you have the number changed for that note, place the cursor at the end of the text of the first note and press Enter. A new consecutive number pops up. Press Backspace several times to delete that number, and when the next existing note moves back to its original position, that note and all the remaining notes below it will renumber consecutive ly."

NOTES FROM CADALYST TIP PATROL: As usual, we ran this tip past two Tip Patrol members for review. One told us, "Wow, this is a really nice trick. Works just as described, and it will come in handy."

Patroller No. 2 agrees that this is a workable tip, but has his own take on the topic. He suggests using features already present in the AutoCAD Mtext text editor. "For example, in AutoCAD LT 2006, you can turn the numbering option on and off, and it renumbers lines that were not initially numbered and remove the numbers on those that were." Another concern is that this tip necessitates that users be conversant with changing their default Mtext editor (and back again later) via the Tools / Options / etc., he notes. "This is not a bad thing, per se, as long as users remember to switch back when they are done."

Autodesk Map Partial Delete
Autodesk Map user G. Sivakumar offers a simple AutoLISP tool, PARTIALDELETE.LSP, to help delete a series of vertices in closed lwpolylines, such as buildings, parcels and the like, in drawings. He uses the Pedit command to complete some manual work, then runs his routine to delete the required portion of a polygon with a few clicks. After loading the routine, start it by typing Pdel at the Command prompt. Next, pick points to delete on a lwpolyline only and the parts of a polygon are highlighted. Use the mouse Reset button to select an alternate part or to pick to delete the highlighted part.

NOTES FROM CADALYST TIP PATROL: This tip works just fine, Patrollers report -- even in AutoCAD (but not LT).

Follow-Up: Get Gatte
Dave McKone offers another option to the Gatte command discussed in the January 15 edition: "Another option is to use Find (right-click or typed-in) and either select the blocks, dtext, mtext or attributes (or any combination), or within the entire drawing. In the fields, type in the current text string and then what it is to be changed to and select Replace All, or Replace (to change them individually). A message is displayed in the lower portion of the dialog box indicating the number of occurrences replaced."

Follow-Up: Continue Arcs
In regard to January 29 edition's Continue Arcs LISP routine, Tip Patroller Donald Reichle reminds users not to forget about AutoCAD's Lengthen command. He explains, "I started to use it shortly after its appearance in Release 13 and have certainly enjoyed the options it has provided. I've even adapted some aliases to make use of this fine command."

(defun c:lgd () (command "lengthen" "de") (princ))
(defun c:lgt () (command "lengthen" "t") (princ))
(defun c:lgy  () (command "lengthen" "dy") (princ))

Follow-Up: Spell Check and Solid Solprof
Kevin Loth finds that AutoCAD's spell check, as discussed in the January 28 edition, is a "nice tool, but it doesn’t work on all text entries. For example, I have AutoCAD Mechanical 2007 and spell check ignores my mechanical notes."

Kevin also notes that he has difficulty with the Flatten command that was mentioned in the January 29 edition in regards to January 22 edition's discussion of Solprof. He states, "The Flatten command is no longer available in AutoCAD 2007, and I don't recommend using it. Simply draw a 10 x 10 x 10 cube and flatten it (using AutoCAD 2004) and it will no longer be 10 x 10 in 2D. The Overkill command is not foolproof, either. I have had geometry change from using it."

MicroStation Tip -- Permanent File History
Question: Is it possible to always have a link to a frequently used design file? The Last Used file history always shows the last four files used, which is OK, but I wish there could be one or two permanent shortcuts to certain files.

Answer: You can use key-ins newfile design_file or RD=design_file. Both key-ins open the design_file. Then write a simple macro that writes out one or more text files that do a newfile to the files you want to open and then assign function keys or menu items to those text files. You can also hardcode these commands into menu or function keys.

Find this and many other MicroStation Tips on Axiom's Web site.
