Error message when using the extension Dimensions

Postby Konive » Fri Jan 25, 2019 11:34 pm

I'm using Inkscape 0.92.4 for technical illustrations and it is doing a great job. The one big gap I have to fill is adding the dimension annotations. I have tried all the tips like Visualize Path or the Measurement tool, but nothing is even close to be a solution. There is one extension that would be perfect:

Dimensions from fsmMLK.

But whatever I do, I get a python error back.

Code: Select all

Traceback (most recent call last):
  File "dimensions.py", line 838, in <module>
    dimension.affect()
  File "inkex.py", line 283, in affect
    self.effect()
  File "dimensions.py", line 196, in effect
    [P1,P2] = self.getPointsLinDim(element,so.LINdirection)
  File "dimensions.py", line 790, in getPointsLinDim
    [P1,P2] = self.getPoints(element)
ValueError: too many values to unpack


At work I'm using a portable 0.92.4 on Windows 8.1, at home I tried an installation with Windows 10 and installed Python 2.7, but the error is the same. I did not install LaTEX and have disabled the option in the extension. I added a simple drawing of a standard pallet for the chemical industry, but I don't think this is the reason for the failure.

Hi.

Try the development build. It has a dimensioning path effect =updating the measures in real time.

Make a bug report by opening an issue on the extension's code hosting site (there's a link to github on the page you linked to: https://github.com/fsmMLK/inkscapeDimensions ), so the author can fix the extension.

@Lazur
I need it at work and there I can't install a Linux VM. I will see what I can do with GCC or MSYS2 at home, but this isn't exactly my field of expertise.

@Moini
I hoped I made a simple mistake and it is not an error of the extension itself. Did you get a similar error?

You're right. Make sure your measure line (the one that you add to the drawing) only has the allowed number of nodes. See https://github.com/fsmMLK/inkscapeDimen ... /README.md

Was referring to this lpe.

There is a link to a running win standalone version.

D**it, read so much, but missed the part with the auxiliary lines. Using the KISS principle I played around with a blank drawing and singular lines and angles. Angular worked immediately, but straight lines always gave this error back

Code: Select all

Traceback (most recent call last):
  File "dimensions.py", line 838, in <module>
    dimension.affect()
  File "inkex.py", line 283, in affect
    self.effect()
  File "dimensions.py", line 202, in effect
    horizontalText=so.LINhorizontalText,invertTextSide=so.LINinvertTextSide,smallDimension=so.LINsmalDimStyle)
  File "dimensions.py", line 603, in drawLinDim
    value=self.userUnit2unit(value,self.documentUnit)
AttributeError: Dimensions instance has no attribute 'userUnit2unit'

To fix the problem you have to use the last version of another extension fsmMLK wrote, InkscapeMadeEasy.

@Lazur
I will annotate a few drawings colleagues are waiting for, then I switch to this α. Should I report here or in the thread with the download?

Exactly. The extension requires another python module to function.

Bug reports should go to https://gitlab.com/inkscape/inbox/issues/

I wouldn't recommend to use the alpha for production, just for testing. Depending on your operating system, there are a couple of possibilities how to have more than one version of Inkscape installed.

Yeah, I already had downloaded InkscapeMadeEasy, and definitely after November, but this commit wasn't included.

I'm running into a problem with disappearing markers on arrows. There were some bugs filled for this, but all seem to be solved. I don't think this is introduced due to the use of this extension, but I want to make sure. The markers are there, they reappear when I copy the line to another sketch. After ungrouping the arrowheads are back, but after scrolling or adding another annotation they are gone again. Not all, and with no obvious pattern. I replaced the lines drawn by the extension but get the same behavior as well.

System: Inkscape 0.92.4/VM on Windows Server 2008 R2 64bit.

I can't reproduce this, although I'm still using 0.92.3. But it sounds like a display issue.

When you say it looks like the bugs you found are solved, do you mean the bug reports indicate "Fix Released"? If you found a bug that seems to fit the problem that you see, it's probably a good idea to report it. Maybe it's not fixed after all? Or it could be a different problem.

For 0.92.4, it should be reported here: https://gitlab.com/inkscape/inbox/issues (click on the green New Issue button) But be sure and include links to the (launchpad) report or reports which you think might be related.
