LibreCAD Subject description: free CAD package with DXF support standard |
|
I stumbled on the LibreCAD project by chance.
It is a fork from Qcad, which only now provides its limited community versions free.
LibreCAD aims to be 100% Free and is rocking along in its development.
Its good for working .DXF files without the limitations of Qcad Community version (like no polylines).
I got it working in Lucid Puppy, but with some pain.
It won't compile no matter how I set things up with qt4 libraries and the like.
But a Lucid compiled Unbuntu .deb will get you home, plus an upgrade of the qtnetwork library.
First the homepage - they are developing it further so watch this space
http://www.LibreCAD.org
Its qt4 based so you need basic qt4 support in puppy first:
Qt4 support for puppy I found here as sfs files:
http://www.smokey01.com/pemasu/Sfs/qt4-4.8.0.sfs
And the development libraries (not sure if I really needed them, I did while trying to compile it, but they may help out)
http://www.smokey01.com/pemasu/Sfs/qt4_DEV-4.8.0.sfs
Now the ubuntu packagaes that got it working for me:
You need qt4-qt3 support
http://packages.ubuntu.com/de/lucid/i386/libqt4-qt3support/download
..and the qt4 network library that didn't seem to be in those sfs files
http://security.ubuntu.com/ubuntu/pool/main/q/qt4-x11/libqt4-network_4.6.2-0ubuntu5.2_i386.deb
The package
https://launchpad.net/~showard314/+archive/librecad/+files/librecad_1.0.0%7Ebeta5-1%7Eppa1_i386.deb
Data
https://launchpad.net/~showard314/+archive/librecad/+files/librecad-data_1.0.0%7Ebeta5-1%7Eppa1_all.deb
Docs
https://launchpad.net/~showard314/+archive/librecad/+files/librecad-doc_1.0.0%7Ebeta5-1%7Eppa1_all.deb
Enjoy

Thanks disciple - I found the thread for Draftsight and an sfs file.
Will compare later to see what is good for my needs. I could imagine both being useful tools.

Linux tells what is missing ... ... seems libQtNetwork.so.4 or all Qt files are missing.
Read first post above to check all needed Qt dependencies are installed.
Greetings, Charlie

No, that is saying it is installed, but it is not the same build as the program is linked against (Built with different options or something). Maybe you have two builds from different distros or something installed in different locations in your $PATH

@ chimnya123
If you have done several QT installs, chances are some parts are not agreeing with each other, version wise or how they were compiled.
QT is a monster - so its easy to get it to tie itself in a knot.
TIP: If you are going to use it often, make a savefile (if frugal install or similar) just setup for CAD with the QTs for librecad - no collisions.
I basically made a lupusave or a fatdog savefile setup for all of my CAD apps - all built from a fresh start so nothing collides, and took notes one by one as I installed things until everything was happy.
As soon as anything went crazy I retraced my steps and weeded out the offending app or library.
Big programs have a habit of having heaps of libraries and the more you have the greater the chance that they don't like each other.

If anyone wants to try this, I just compiled, & uploaded, librecad + needed qt4 library files, as an sfs here:
LibreCAD-2.0.6.sfs
It's a 17.5Mbyte download. I've tried it on slacko-5,7 and upup raring & it seems OK. Let me no whether it works for you.
( The only thing I'm not sure about is whether there will be any conflict with existing Qt4 library installation).

- Any idea how to 'group' or 'connect' two 2D entities together? I have made one object placed offcentre inside another shape and want to rotate the two without losing their positions relative to each other. Sounds like I need to use block and layer functions but haven't figured it out yet.

I use QCad but a suggestion from there may work. You can select multiple parts and move them etc. When you do, they move together without grouping.

I can select all of the items I want to combine but then I found I was unable to move them. Must be using the wrong technique. Did Qcad have the 'block' feature - is that how you were able to move a cluster of selected items as one block?

Thanks very much, muggins..!
Just tried this on Slacko 5.7.0; working a treat. Been looking for an SFS of this for a while now. Lovely work.
Cheers.
Mike.
