One of its unique features/characteristics is that it has a very highly customizable interface that allows users to customize toolbars and menus. It is also a popular DWG and DXF file format viewer and users can also use it to save drawing in DXF, and SVG, among other formats. Isometric projections are at times referred to as 2.5D drawings. The orthogonal projection is for creating 2D drawings while isometric projection allows users to represent their 3D models in 2D. LibreCAD is used for producing orthogonal and isometric projections. Operating Systems: Windows, macOS, and Linux.Current stable release: LibreCAD v2.2.0-rc1.The CAD application has gone on to port to Qt5 which is even more advanced than the Qt4. QCad was initially built on Qt3 library which was becoming outdated and it had to be ported to a more advanced library, the Qt4, and its name was changed to CADuntu.Īfter a few months, the community decided that the name CADuntu was inappropriate and they changed it to LibreCAD. LibreCAD was started as a project for incorporating CAM capabilities into the QCad so that it would be with the Mechmate CNC router. Importing Freehand Sketches into LibreCAD.I have a finals week during the week of the 23 May, I'll do some work on the selection part during the community bonding period to not having too much delay on the schedule. I can work at least 40 hours a week and more if needed. I have a good experience with C++, Qt and Lua as required for this project.Īs I already worked with CAD softwares, I understand the users And I think LibreCAD 3 hasĪdvantages over some proprietary CAD software, it is faster to start. With Linux which allows me to do what I need. I used some CAD programs before and LibreCAD is the only one compatible Operations on entities exposed to the user.This project will add the following features to LibreCAD 3:
Prompt to enter Lua code, so instead of writing all the Lua script, the userĬan select the elements on the window and just enter one function. The main window will contain the buttons for each actions and a command New bindings will be created to manipulate Qt elements with Lua.Īn API will be created to allow the framework to request data from the user.
The current Lua interpreter contains Qt bindings¹ but it’s only the data It will be composed of Lua scripts for the same reason as the framework. The framework will be called when an operation is selected and shouldĪllow the user to enter data manually in the console, or automatically in the The GUI should contain all the elements to create and manipulate entities. Lua will be used for this part, the actual kernel bindings¹ The framework will be scriptable so we can modify the interface without It will be called by the UI for each user action and will be composed of anĮlement for each entity available in the kernel. The framework should be able to deal with all the methods used to createĪnd modify entities, for example a circle can be created by giving two It must be extendable to evolve with the code. Others CAD programs could use the LCv3 engine and it can facilitate the The constraint is to be independent of drawing engine and input method, so The framework should allow to create and modify entities stored in the The user can modify the document by moving these points. The kernel will need a modification to add the possibility to select one orĪ new method will be added to the entities to get their definition points, that will be displayed when hovering them. This project involves working with the LC user interface by creating aįramework and a GUI, and the LC kernel to add the selection of entities.Īctually items selection is only available in the drawer¹, not in the kernel. LibreCAD 3 is currently divided into 3 parts: This project aims at making the program usable for an end-user, who should be able to create and edit documents without writing Lua code.
Currently the only way to create objects is writing a Lua script, and there is no means to manipulate entities after their creation. LibreCAD 3 Scriptable User Interface Creation Brief project summary
