Script to measure distance

Bab · March 25, 2003, 4:19am

Hello, I’ve found a script for distance measure here

jms · March 25, 2003, 10:28am

I wrote this script to answer a question on the
french zoo-logique.org/3D.Blender forum.

You can find an improved version here:

very cool jms

Tried the script in callipersquare03.zip, but in blender 235 it just loops endlessly.

Before i found this thread i made a small script myself:

Thanks for the info&link.

1 question though:
What could be the reason that the BGL line isn’t drawn?
You mention on your site that the script needs to be attached to an object not a scene, but what does this mean… or better how do i do that?

Thanks
Pontiac

Sorry,

just rename the script : mesure.py

pontiac · January 7, 2005, 9:54am

No change in behaviour.
The only feedback/error i get is this error when I first start the script (without selecting anything):

Traceback (most recent call last):
  File "&lt;string&gt;", line 57, in ?
AttributeError: no such Blender Text.

The created Empty is resized and its text changed every time i start the script after that.

Thanks again fopr your help,
pontiac

Very curious. If you have a moment to try this file:
http://jmsoler.free.fr/util/blenderfile/py/mesure.blend

pontiac · January 7, 2005, 11:46am

This file seems to work just fine.
The line is drawn and the text is updated on move… cool 8)

I think in the .py file the link to the generated object (however this works) isn’t created correctly (but it may be my fault :? )

(Just to get sure i also tried to use the source from the .blend file in the .py file, but the line-drawing didn’t work here too.)

You can use shift-f1 to import the script
edit the script and do a alt-p on the text window.

pontiac · January 7, 2005, 1:43pm

When i try to load the “mesure.py” fille i get the error “ERROR: Not a library”

But the script contained in the .blend (e.g …/mesure.blend/Text/mesure.py) file is no problem to use as a library… works as expected, but needs to be loaded verytime i start blender :?

(After loading as lib i can also use the script over the Misc menu instead of the Alp-P in Text-Window)

PS: I’m still using Blender 2.35 if that makes any difference.

You can download the script with the correct name now.

pontiac · January 8, 2005, 9:21am

If you mean this file:
http://jmsoler.free.fr/util/blenderfile/py/mesure.py

It still says “ERROR: Not a library” when importing it with SHIFT+F1
(A sidenote: And in this file the registration with the menu is missing too… which is quite handy)

I hope i don’t bug you too much since it’s just a minor problem to reload the script at every blender start
If so just ignore me and my whining

Ok, i added the script into my “User defaults” setting, so no more reloading the script for me
Didn’t know that this is possible before.

Thanks again for this little helper

if you find it usefull save this script with the current file in the Default Settings with the shortcut : ctrl-u .

jms · January 8, 2005, 10:01am

I did a little improvment, try to reload the script from its url
I think that it could be loaded from the script menu now.

(thx for all your comments )

That’s what i did one posting above (last page) … you just missed it

Just tried it and it seems to even work without having to load it as a library.
I’ll test it and comment here.

Many thanks,
Pontiac

The script is working fine so far, one thing about the code though:

Shouldn’t this part of the code

     if E.getScriptLinks('Redraw')== None : 
        E.addScriptLink('mesure.py','Redraw')
     elif 'mesure.py' not in E.getScriptLinks('Redraw'): 
        E.addScriptLink('mesure.py','Redraw')

be replace with this:?

     if E.getScriptLinks('Redraw')== None : 
        E.addScriptLink(NAME,'Redraw')
     elif NAME not in E.getScriptLinks('Redraw'): 
        E.addScriptLink(NAME,'Redraw')

…since there is now a variable to specify the script-name

EDIT: and a version entry would be great to keep track of the changes made to the script … e.g:

__version__ = "0.1.0"

Just my 2c
