LEOCAD(1) General Commands Manual LEOCAD(1) 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 Loads the project file 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=Out- line 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 coor- dinate system. --camera-position-ldraw x y z tx ty tz ux uy uz Set the camera position, target and up vector using the LDraw coor- dinate 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 re- spectively.) --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 respec- tively.) --shading wireframe | flat | default | full Select shading mode for rendering. --line-width width Set the width 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 float Set the near and far clipping planes used to render images (1 <= near < far). -ldv float, --light-dark-value float 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.
