Logo Contest Entries – Logo Voting Begins

Hi everyone,

I’m sure that you all have been looking forward to the start of the contest, so let’s take a look at the entries. There were a wide variety of designs submitted, and in many sizes and formats. I have tried to present them here in their original format and original size, but sometimes that was not possible due to website requirements. Some larger images have been distorted (squeezed) horizontally due to the website image size limits. You might be able to see them in their original form by following the original links in the previous post. Also, it’s the artwork and concept that count, please don’t worry about whether the images are “too big” or “too small”, I didn’t try to scale them all to the same “pleasing” size.

With that in mind, let’s review the entries:

[ This image I did crop to remove the desktop clutter, but I moved (kept) the small icon near the ruler. ]

[This next entry was submitted as a 64×64 svg, but for some reason it appeared to be 3.0MB, so it had to be converted to a png.]

Need a logo

Hey All,

it’s been a couple of weeks again since my last post. I have been squashing a couple of small bugs but today we got a request on what’s the status is on LibreCAD and if they can get it in the archives for 11.04. I think this is good news!

My ownly objection would be that we don’t have the following graphics:

  1. Small icon log:  To be used in menu entries
  2. Splash screen graphics: Shown when program starts
  3. Program icon: To be used as desktop icons, icon in OSX and program icon.

Since we can have a big graphic on the splash screen I though it would be nice to show a drawing there from a open source hardware projects that was designed in LibreCAD. We could even ‘rotate’ this splash screen image with each new mayor or minor release of LibreCAD?

So, if you are graphically skilled please post to this thread 3 links to your designs. When we have a couple of nice designs I will setup a poll so we can decide what graphic to use. We could also have multiple winnars, if you like the logo of person A but the splash of Person B. We can do this aswell. The winners names will also be listed in the about dialog of LibreCAD.

Good Luck!

Ries van Twisk

Contest will be run until Monday 12AM 31th of Jan 2011. After that I will post all submitted images in new blogpost with a poll for the community to select there favorites.

So LibreCAD it is.


Seems like we have a clear winner, 1:7 CADuntu vs LibreCAD and LibreCAD won with 140 votes against CADuntu that had only 20 votes. So, goodbye CADuntu and welcome LibreCAD

I like the name! Nitro came up with the name first here, the domain LibreCAD.org was free and the name is what it is. Libre (as in free) and CAD as in Computer Aided Design. A very proper name for this project. I contacted SourceForge and asked them the process to change the Project name as this is currently not automated, and if everything is fine you should get redirected already to the new domain from the old caduntu.org domain.

Something more:

Scott has been VERY helpfull setting up a PPA for this project so that the Ubuntu folk can easily install LibreCAD on there systems.

For Ubuntu 10.04 use:
sudo add-apt-repository ppa:showard314/librecad
sudo apt-get update
sudo apt-get install librecad

for Ubuntu 10.10 and Natty use:
sudo add-apt-repository ppa:showard314/ppa
sudo apt-get update
sudo apt-get install librecad

So, now I am going to setup my server to serve LibreCAD and make sure DNS records are changed!


CADuntu Beta 4

Hello all!

I am in the middle of moving to a other house, but I guess I can spare a couple of minutes to create a new blog entry.

A couple of weeks ago, I released a Beta3, and shortly after user found some issues, so I never officially announced a Beta 3. I made all changes and here it is… Beta 4!

So what’s fixed then in 3&4?

  • Button/text overlap in toolbar area : 3101744, 3101614
  • Restore and save dockstate: 3091386 patch by Rallaz
  • Replaced older dxflib with new dxf library
  • Added polyline support: from Jan’s qcad free
  • Fixed crash on command line interaction: 3098531 reported by Adamzone
  • Fixed library browser : 3090688, reported by Rallaz
  • Fixed empty images during export: 3095753
  • Closing app works now correctly, when pressing cancel you really cancel: 3103190
  • Layers can be deleted, so as blocks: 3102199, 3105191 reported by rodrigopitanga
  • utf-8 support for layers and block names :
  • Menu errors (also in QCAD) : 3092018 reported by Robert
  • Switching between multiple drawings: 3056455 reported by sliptronic
  • Add some default libraries so the library browser show something.
  • More little things and stuff…

So, all in all I think CADuntu is much more mature now and I am really happy with the support from everybody! There is much more to come, but personally I am hoping to start working on my CAM additions so I can finally put my Mechmate to good use!


What I am currently working on…

A quick update to let you know what I have been doing.

Some people have been supply bug reports to the sourceforge page, and I want to thank them again for doing that, if you didn’t and found a bug or want a feature, let me know on the bug tracker!

At revision 70 I fixed the library widget, thanks to the patch from Rallaz, apart from that a little work was needed to make sure that libraries in a users home directory could picked up and that thumbnail generation worked properly.

I asked Andrew if I can include his Part Library in the CADuntu release because no license information was given, however you are free to download his, or any other parts library and put it in you library directory for your platform.

  • Linux/Unix users : ~/.caduntu/library
  • OSX users use : ~/Documents/CADuntu/library
  • Windows user use : c:\Documents and Settings/<your username>/My Documents/Caduntu/library

CADuntu Library browser

Rallaz also prepared RPM’s for the following Linux distributions : OpenSUSE, Mandriva and Fedora they can be downloaded from this location : http://download.opensuse.org/repositories/home:/Rallaz/

Robert von Knobloch Submitted a bug report where a couple of menu entries where incorrectly displayed, this was solved in patch 69 and 70, thanks Robert for that, I completly over looked it.


Another fine Beta (2) release of CADuntu


I just released a other Beta release of CADuntu. More issues have been solved and CADuntu keeps looking better each day, I am very happy! Also I am happy to see that the community is picking CADuntu up because there are now many blogs (here, here, here and here……. and here ) that wrote an article about it, thanks to everybody! This makes it even more worth to keep working towards the release candidates and final releases.

What has been improved in CADuntu?

  • Fixed 64 bit builds
  • Fixed hatches not showing up (Yan Zagorskih)
  • Better dialog size handing for some dialogs
  • No more toolbar clutter on the left hand side (Reported by Sliptronic)
  • Improved installer for XP, Vista and Windows Seven
  • Improved status bar message handling

I already got some reports that CADuntu didn’t work on a 64Bits OS like here so I also fixed and tested this on a Debian 64Bits, this would make all 64Bits users very happy. I got in a patch from Yan thanks! that found a bug with hatches, that where not shown up correctly. Also there was a bug where during operations the screen wasn’t updated properly. For example when you selected a line in trim mode, the line would not show up as selected.

With 266 downloads (as of today) am am very happy with the result and how this was picked up you can download a new version at SF overhere: https://sourceforge.net/projects/caduntu/files/

Beta1 status is reached!

Today I was looking at my roadmap, and it pretty much looks like I reached my beta1 status goal. In my first post I did mentioned I needed to have the following solved for beta release:

  • Make it work as if you are on QCad CE, but then with the qt4 interfaces – DONE
  • Fix all segfaults – DONE

However, not only that was solved, I also managed to make basic OSX and Windows packages. They are pretty much ‘bare bone’ and for OSX I really want to make a DMG installed, but now it’s just a zip. Most people on OSX would know what to do with that, right?

Anyways, for windows I created a NSIS file that will be soon committed to SVN so anybody that knows NSIS better then me, and that should be pretty much everybody that knows NSIS can create a better version.

Hope you enjoy this version of CADUntu and please leave a comment if it worked, or if not worked for you here or in the tracker in sourceforce.

Moved away from forms3, hurray!

I just committed a new version of CADuntu, with it’s main ‘new’ feature that I moved away from using forms3 and uic3 and the forms now are natively qt4. That said, the project didn’t move away your from q3support so that’s still in there. I feel that this isn’t really a real biggy, as long as the software works as it suppose to work, right?

I still have some standing issues reported by sliptronic and I feel that they are annoying enough to keep this software still in Alpha. Sometimes the icons seems to clutter, and text queues in multi-step operations are not shown correctly. These are somewhat the more harder items to tackle because I haven’t played around much with that area of the software. However, in reality I haven’t seen any crashes anymore since a update a couple of weeks ago.

I would like to invite you to try and compile it, if you want I could make a screencast how to compile and run on Windows. It’s really not at all that hard, you only need a SVN client like TortoiseSVN and the QT4 SDK (use the lgpl version), even I could do that on windows!

anyways, I truly hope I can make a binary release for windows pretty soon as soon as I have figured out how to make a install script. Somebody suggested to use NSIS

Bug fixes and new selection box

CADuntu's new selection boxSliptronic has been giving me a lot of feedback lately, and I am trying to squash the bugs as fast as he puts them on my desk, It’s kinda fun  working this way and I am very grateful he does test CADuntu and provides feedback. So today I have been working on getting the screen properly updated after a entity is de-selected. There are/many of these sort of issues because the way QCad used to renders on the screen isn’t supported by Qt4 anymore. Mostly notiably XOR operations during drawing and in Qt3 3 it was possible to draw outside of the paint event. With Qt4 all this work has been brought inside the paint event. For this, 3 QPixmaps where created:

  • Layer 1 -> Draws grid and paper, basically the bottom layer
  • Layer 2 -> Draws the actual drawing
  • Layer 3 -> Draws the overlay, items that are currently in action like moving and drawing of lines, but also the Snapper and selection boxes.

This will speed up overlay performance of CADuntu by not drawing everything over an over again unless we have to. Second, by moving this all in the paintEvent we can take advantage of graphics acceleration.

So, today I worked on getting the [Edit] menu fixed with proper check marks for [Grid], [Draft] and [Status bar] and with accelerators so they can be accessed through they keyboard commands.

On last item I made today, was a colored box with alpha layer selection of entities. This looks a lot better, and I feel it’s much more clear then the original cyan colored rectangle. Here is a small video that snow’s that in action : http://screencast.com/t/MzMyYzg5O
