About LeoCAD Mod

LeoCAD is a CAD program for creating virtual LEGO(R) models. It's available for free under the GNU Public License v2 and works on the Windows, Linux and macOS Operating Systems.

This repo is my mod adding these ease of use enhancements:

• Add keyboard shortcuts (mnemonics) for menu items. E.g.:
  • In Timeline: insert steps before, after; move selection here...
  • Various commands in main menu.
• Easier parts search via Search Parts textfield.
  • Specify brick sizes without spaces. E.g. key in just 2x2 instead of "2 x 2".
  • If exact phrase (search text) does not match, also try matching all keywords in search text. So you don't have to know exact phrasing of the part.
    • E.g. to find "Brick 5 x 5 Corner Round with Slope 45 Chamfer", you don't need to remember and key in "Corner Round with Slope" exactly. Just key in "slope corner" or any of the keywords (even partial keywords) to search for.
• Alternative to Edit> Replace command: New command Piece>Replace which replaces selected bricks with the one in Parts panel.
  • Hotkey: CTRL+R; mnemonic: R.
• Open .LXF - as an import. So you can associate .LXF files with LeoCAD, to open them easily.

Enjoy ",

Installation

You can download the latest version of LeoCAD and its Parts Library from the main website at https://www.leocad.org

It's recommended that you install the latest drivers for your video card since LeoCAD uses OpenGL to take advantage of hardware acceleration for rendering.
