General Options

Save toolbars state
	When this box is checked, the toolbars size and position will be saved and restored the next time you start LeoCAD.

Save window position
	When this box is checked, the window size and position will be saved and restored the next time you start LeoCAD.

Print step numbers
	Print numbers indicating the current step

Use brighter colors
	-

Hide sub-parts
	Hides the parts that begin with a tilde (~) from the parts list.

Show part numbers
	Makes the parts numbers visible on the parts list

Show part preview
	Show/hide the part preview window

Zoom part preview
	Automatically zooms the part preview to fit the part displayed

#K $ 
Detail Dialog

Draw backfaces
	When this box is not checked, only polygons that are facing the view will be drawn.

Wireframe
	Draw a simple wireframe version of the bricks.

Draw studs
	Tells LeoCAD to draw or ignore the studs on the bricks.

Draw studs
	Draws a box instead of studs. When checked, there’s a speed increase of about 35%.

Use clear colors
	When this box is unchecked, transparent (clear) colors are replaced by their opaque version. Transparent colors are slower to render than opaque colors.

Brick edges
	Draws a thin border around the bricks. If you want to print instructions for a project, turn brick edges on and lighting and smooth shading off.

Dithering
	Turns dithering on/off, will only make a significant difference on 8-bit displays.

Depth test
	If enabled, do depth comparisons that are used when one polygon is overlapping another one.

Lighting
	If enabled, use the current lighting parameters to compute the color of each vertex.

Smooth shading
	Smooth shading, the default, causes the computed colors of vertices to be interpolated as each face of the object is rasterized, typically assigning different colors to each resulting pixel fragment. Flat shading selects the computed color of just one vertex and assigns it to all the pixel fragments generated for each face.

Anti-aliasing
	If enabled, draw polygons with proper filtering, otherwise, draw aliased polygons. This option should only be used by computers with 3D hardware or for saving a bitmap, as it drastically reduces the frame rate.

Line width
	Specifies the width of the lines used.

Filled boxes
	Draws solid boxes instead of only the edges.

Remove hidden lines
	Removes lines that shouldn’t be visible.

#K $ 
Drawing Aids Dialog

Base grid
	Draws a grid on the base with spaces of one brick wide on the XY plane.

Show axis
	Show the direction of the axis.

Snap X / Y / Z
	Only allows movement of parts on the X and Y direction on half brick wide increments, and on the Z on flat brick height steps.

Collision check
	Checks bricks for collision when they are moved or rotated.

Move after insert
	Automatically changes the mouse mode to ‘move’ after inserting a part.

Lock X / Y / Z
	Disable movement and rotation of bricks on the selected direction.

Angle snap
	Only rotate bricks on the given amount of degrees.

Keys move on fixed axis
	Makes the left and right keys always move the selected brick along X axis, and the up and down key move the on the Y axis.

#K $ 
Scene Dialog

Fog Options:

Enable:
	Turns fog on/off.

Density
	Fog density, from 0 to 100.

Color
	Fog color.

Use Background
	Use the same color used for the background.

Background Options:

Bitmap
	Select a windows bitmap file to be used as the background. The checkbox enable/disable the use of the bitmap.

Color
	Choose the background color.

Tile
	Repeat the bitmap when the box is checked, otherwise it will be stretched to fit the entire viewport.

Fast
	Do not draw the background when drawing only boxes.

#K $ 
Camera Dialog

Position
	Eye position.

Look At
	Point to look.

Name
	Camera name.

Near/Far Z
	Front and back clipping planes.

FOV
	-

Note: The Z direction is the height, always pointing up.

#K $ 
Array Dialog

Move
	Distance between pieces.

Rotate
	Angle between pieces.

Total in array
	Total number of pieces (or groups of pieces) in the array. Must be greater than 1 or the command won’t have any effect.

#K $ 
Export to POV-Ray Dialog

L2P Executable
	Location of the file L2P.EXE, for example “C:\LGEO\L2P.EXE”

POV-Ray Executable
	Location of PVENGINE.EXE, like for example “C:\POV-RAY\BIN\PVENGINE.EXE”

Output file
	Name of the file created by LeoCAD. Two files will be created, one with the .POV extension that contains camera and light information, and another with the .INC extension that has the actual model.

Render Scene
	Call POV-Ray to render the file after conversion.

Notes:
	To be able to export a file you will need to have the LGEO library and the L2P program correctly installed on your computer, both can be downloaded from Lutz Uhlmann’s homepage at http://titan.informatik.uni-bonn.de/~uhlmann/ and obviously you will also need to have the POV-Ray renderer, you can get it from http://www.povray.org

	After LeoCAD exports your project, you should edit the .POV file created and add more lights, change the background or move the camera around. The file that is created is a good start for those things, but if you really want to have a good image you should make some changes yourself.

	The LGEO library does not have as much parts as LeoCAD does, but you will be able to correctly render most models with it. I have only tried to convert files with L2P 0.5 and POV-Ray 3.0, I don’t know if it will work with older versions.
