    1918'''4. How can I export a model to use with LDraw?'''
    2019
     
    2625Just place the piece and all its unofficial subpieces and primitives properly in the LDraw folder (you must have the LDraw library installed to do this).
    2726
    28 Open LeoCAD, go to the Piece Library manager (in the File menu) and then select Import Piece on the File menu of the PLM. Once you import all pieces restart LeoCAD and they should be visible in the library.
     27Open LeoCAD, go to the Preferences Dialog (in the View menu), go to the General tab and then enter the path to the LDraw library on the Custom Library field.

    3129
    32 Not at the moment, I would like to write a Machintosh version but I don't have a Mac. If you're a programmer and you want to try to do it yourself, join the developers mailing list.
     30'''6. How can I create new pieces?'''
     31
     32LeoCAD uses the LDraw file format for pieces, you can find out more information about the format and the tools used to create pieces on the [http://www.ldraw.org LDraw] website.

    37 '''1. The print/print preview freezes my computer and the HD goes crazy.'''
    38 
    39 The computer is not frozen, as Windows 95 can't print an OpenGL image directly, LeoCAD creates a bitmap in memory and then prints that bitmap. If you are using a high resolution printer, that operation will take a lot of RAM memory. Here's an example, suppose that you want to print something with a 600 DPI printer on a sheet of paper A4, the bitmap would be 8.27 inches x 600 DPI x 11.69 inches x 600 DPI x 3 bytes (24 bits) = 100 MB just for the bitmap.
    40 You should go to the preferences dialog and check the box 'Low quality' under the 'Print' tab, that will make LeoCAD use 75% less memory but the quality will be a little worse.

     42'''1. LeoCAD used to work fine but now it crashes on startup and I can't live without it!'''

    4544Try running "regedit.exe" and delete the folder "HKEY_CURRENT_USER\Software\BT Software" and it will work again.

    48 '''3. I try to run the program but I get a crash on startup.'''
    49 
    50 Most regular PC video cards are tested mainly with games and LeoCAD uses the hardware more like a CAD program so a lot of times it ends up finding bugs on their drivers. The first thing to try is go to your manufacturers website and download and install the latest drivers available for your video card.
    51 
    52 If that doesn't work you can go to your Windows desktop, right click on the "My Computer" icon and select "Properties" from the menu. A dialog will appear, click on the "Advanced" tab and move the "Hardware Acceleration" slider all the way to the left. If this fixes your crash then the bug is in your video card drivers.
    53 
    54 ATI cards are a good example of bad OpenGL drivers, if you get a crash and the message says "LEOCAD caused an invalid page fault in module ATIO9XAA.DLL" then you have bad drivers. You can try what's listed above or simply rename the ATIO9XAA.DLL file on your windows/system directory.

    75 Leocad is actively developed on windows at present, and some features are not translated to linux as often, or at all when they are developed for Windows. If you have linux coding skills, we could definately do with the help. Until then, you may get joy running the windows version of this in Wine/Transgaming.
