I downloaded the most recent release, pyslvs-18.2.0.glibc2.17-x86_64.AppImage. It does not work on Debian Stretch 9.3.

$> ./pyslvs-18.2.0.glibc2.17-x86_64.AppImage

Maybe you want to reach out to the IRC channel #AppImage on Freenode. There you'll find AppImage developers who are willing to help fix any problems you may have with packaging and testing your AppImage.

Hi! First of all I would like to say that this system is amazing, it works great!

I would like to use this in my thesis with Reinforcement learning in which I am creating mechanism (1-DOF, derived from a fourbar linkage) from python and I need to get the trajectories of those mechanism as fast as possible (3trajectories /second). Is there any way of defining the mechanism in a script and get the trajectories there without using the GUI interface ?

This is how I define the linkages in python currently

Thanks in advance for your help!

@KmolYuan, thank you for the DEB's produced for KUbuntu 16.04, but it look little incomplete (no dependency information included)

What about producing AppImages, that could run on near all Linux-based distributives?

@probonopd, please, take a look and give an instructon how produce AppImage for Pyslvs under KUbuntu 16.04

When try Maximize (Ctrl+Alt+5) program window size of it just freezed.

The only way to change window is manually drag each windowborder or use "Filex -> Full screen (Shift+F1)"

Hi,

I would like to try your software but I get the following error during compilation (make build-kernel):

[...]
 slvs_wrap.o
      SWIG_Py_Void() in slvs_wrap.o
      SWIG_Python_NewShadowInstance(SwigPyClientData*, _object*) in slvs_wrap.o
      SWIG_Python_AppendOutput(_object*, _object*) in slvs_wrap.o
  "__Py_NotImplementedStruct", referenced from:
      SwigPyObject_richcompare(SwigPyObject*, SwigPyObject*, int) in slvs_wrap.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [_slvs.so] Error 1
make: *** [build-solvespace] Error 2

I tried few workaround with no success. Any idea ?

Let the linkage has more interactions on main canvas just like points.

• [x] Merge function to move points to another linkage, then delete the original linkage.
• [x] Select function.
  • Switch selection mode by entities tab widget.
  • Save selected item for each table.
• [x] Free move function for adjust dimension of linkages.

When I open the documentation (https://pyslvs-ui.readthedocs.io/en/stable/python-solvespace-api/) I mostly see some huge search and code icons, it does show a menu but returns 404 errors as I navigate through it. I would love to dig in to this documentation though as I'm eager/curious to use the library for a course I am teaching on Algorithmic Folding (lecture = linkage folding)

so far I tested with Chrome, Firefox, and Safari, happy to test more if that helps

I love this project, thanks so much for putting this together!

Version 0.9 bata 1

This typo mistake should be fixed to "Version 0.9 beta 1". But I also recommend write it as "Pyslvs-PyQt5 0.9-beta.1", and as tag use v0.9-beta.1

Also recommend you read the guide "Semantic Versioning"

• http://semver.org

"Semantic Versioning" now is most popular versioning sheme for user software.

Hi,

this software is really great, thank you for sharing it. I just want to suggest an improvement to make it even better. Would it be possible to add an option to plot time histories of positions, velocities and accelerations for selected points ? It seems that currently these variables can be plotted only with respect to position. Such a feature would be very useful in my opinion.

Hi,

I think that I've encountered a bug. I followed this tutorial: https://www.youtube.com/watch?v=cB5wYyc0J0c

and modeled a simple slider-crank mechanism:

The problem is that it doesn't work properly - you can see that the curves showing paths of points belonging to the mechanism are very short and motion of this linkage can't be simulated. However, it happens only when point 0 and point 2 have the same Y coordinate. When I move one of them slightly above or below the other, it starts working:

I also attached the .pyslvs file packed to zip below. Would it be possible to fix this bug ?
