Topic: Fonts for grvecs

[Lee Mac]

I also love solution, provided by Lee Mac at his Grtext lisp demo.
http://lee-mac.com/grtext.html
It's very flexible on my mind.

Thank you Inciner! 
That is a fantastic way to visualise the vector encoding.

If you entmakex your text there is no need
for transforming fonts.

Similar to Alan's linked example, this is also the method I used in my very old Dynamic Information program; however, I much prefer the far cleaner solution of displaying text using temporary vector graphics, rather than many thousands of additions/deletions/modifications to the drawing database (which may also bloat UNDO cache files).

Bloating the UNDO cache is definitively a possibility.

Can be prevented that turning UNDO Off at beginning of routine
and back on as routine completes.

Creating and Deleting entities as far as I am concerned is a moot point
as it is designed for this exact purpose.  On top of that those grvec vectors
have to live somewhere while you display then.

Yes, but the overhead will be substantially less.

they live somewhere in the wonderland but I have not to be worried about where this place is

I've never thought about this as an issue. Is this something that has always occurred, or just in newer versions? I do notice that, if I've had c3d open all day, doing a lot of heavy work, c3d can become a little laggy, but restarting acad (not computer) will solve the issue.

I can't say whether it has always been the case, but I've certainly seen some pretty large UNDO.ac$ files in the past, with the 'running out of system memory' message not long to follow. I should imagine restarting AutoCAD cleans up the UNDO cache and the application starts afresh on the next run.

AlanJT,

That Undo file certainly grow in the case of such a program
where you keep drawing and erasing to do animation.

However a simple command like

Code: [Select]

(vl-cmdf "_AUTO" "_OFF")
prevents it from growing.

Been like that for as long as I can remember. (And that's a long way!)

I assume you mean

Code: [Select]

(vl-cmdf "_UNDO" "_AUTO" "_OFF")

Indeed! 

Sorry! about that.

[alanjt]

Interesting. Is there an adverse effect to turning off auto all the time?

Keep in mind, I've not experienced undo issues, nor do I create/erase objects for animation.

Execution speed, especially when batch processing dwgs in the thousands may upset peers that prefer to do things the hard (manual) way.

Then I should be worried.

My favorite setting:

(vl-cmdf "_undo" "_control" "_none")

I normally turn it back on on completion of the routine
in the Error Handler, in order to catch the "Escape" artist.

But I certainly like having undo available specially when
testing routines.

Hey People...
Short time ago I wrote a python-script to extract information out of a .pt3 (Font) to generate a lisp-function wich calculates the vertices of a text for the use with grvecs...

curves in the original font are ignored.

Wanna share some Fonts, and if somebody wants, the python-script...

greets

Great works !
dose these font-vectors maked by some tools ,which has a function tanslate shape into vectors ?
