NAME

LeoCAD - CAD program for LEGO models.

SYNOPSIS

leocad [OPTIONS] [INFILE]

DESCRIPTION

LeoCAD is a CAD program for creating virtual LEGO models. It has an easy to use interface and includes thousands of different parts in its library.

OPTIONS

Below is a summary of all of the options that LeoCAD accepts. Many options have two equivalent names, one of which is a single letter preceded by -, and the other of which is a long name preceded by --. Brackets ([ and ]) indicate that an option takes an optional parameter.
infile

-l path, --libpath path

Set the parts library location.

-i [outfile.ext], --image [outfile.ext]

Saves a picture to outfile.ext in the image format specified by ext and exits. If outfile is not given then the program will use a name based on infile. The file format is selected by ext and can be gif, bmp, png or jpg (if ext is not present then the default preferences format will be used).

-w width, --width width

Sets the width of the picture to width.

-h height, --height height

Sets the height of the picture to height.

-f time, --from time

Start saving pictures at the step time. Steps start at 1.

-t time, --to time

Save pictures until the step time.

-s submodel, --submodel submodel

Sets the active submodel to submodel.

-c camera, --camera camera

Sets the active camera to camera.

-ss id, --stud-style id

Set the stud style. Valid values 0=Plain, 1=Thin Lines Logo, 2=Outline Logo, 3=Sharp Top Logo, 4=Rounded Top Logo, 5=Flattened Logo, 6=High Contrast, 7=High Contrast with Logo.

--viewpoint front | back | left | right | top | bottom | home

Sets the viewpoint to one of the predefined view angles.

--camera-angles latitude longitude

Set the camera angles in degrees around the model.

--camera-position x y z tx ty tz ux uy uz

Set the camera position, target and up vector using the LeoCAD coordinate system.

--camera-position-ldraw x y z tx ty tz ux uy uz

Set the camera position, target and up vector using the LDraw coordinate system.

--orthographic

Use an orthographic projection.

--fov degrees

Set the vertical field of view used to render images.

--zplanes near far

Set the near and far clipping planes used to render images (1 <= near < far).

--fade-steps

Render parts from prior steps faded.

--no-fade-steps

Do not render parts from prior steps faded.

--fade-steps-color color

Color to use for rendering faded parts. (#AARRGGBB where AA, RR, GG, and BB are hexadecimal values for alpha, red, green, and blue respectively.)

--highlight

Highlight parts in the steps they appear.

--no-highlight

Do not highlight parts in the steps they appear.

--highlight-color color

Color to use to highlight parts, (#AARRGGBB where AA, RR, GG, and BB are hexadecimal values for alpha, red, green, and blue respectively.)

--shading wireframe | flat | default | full

Select shading mode for rendering.

--line-width width

Set the with of the edge lines.

--aa-samples count

AntiAliasing sample size (1, 2, 4, or 8).

-scc #AARRGGBB, --stud-cylinder-color #AARRGGBB

High contrast stud cylinder color.

-ec #AARRGGBB, --edge-color #AARRGGBB

High contrast edge color.

-bec #AARRGGBB, --black-edge-color #AARRGGBB

High contrast edge color for black parts.

-dec #AARRGGBB, --dark-edge-color #AARRGGBB

High contrast edge color for dark color parts.

-aec, --automate-edge-color

Enable automatically adjusted edge colors.

-cc float, --color-contrast loat

Set the near and far clipping planes used to render images (1 <= near < far).

-ldv float, --light-dark-value loat

Set the value to indicate a light or dark color.

-obj [outfile.obj]

Exports the model to wavefront format.

-3ds [outfile.3ds]

Exports the model to 3DS format.

-dae [outfile.dae]

Exports the model to COLLADA DAE format.

-html [path]

Creates an HTML page for the model.

-v, --version

Output version information and exit.

-?, --help

Display a brief usage synopsis and exit.

ENVIRONMENT

‘‘LEOCAD_LIB’’ may be set to the path of the parts library.

EXAMPLES

$ leocad car.lcd -i car.png -w 640 -h 480

This will start LeoCAD, load the file "car.lcd," create a png called "car.png" with a resolution of 640x480 and exit when done.
