Welcome to Paul'

Ldraw Primitive Generator

This program creates most all the LDraw primitive types in any segment level 1/16 to 16/16, 1/48 to 48/48, and custom/custom.

It is not complete, however I would say it is about 90+% there..

POV code is available for Torus files only. This will probably be removed when L3p supports Torus files.

Zerobase.dat and point.dat files are included for additional viewing options. Place them in your Models or P directory. (See L3lab image below)

This program is still in the development stage, any emails about errors would be helpful.

If you need the Visual Basic Runtime modules, you will need to download them from Microsoft.com downloads section, search for Visual Basic runtime. It should be approx. 1mb.

Ok, here is a few quick shots of the torus's that I have created. My spreadsheet only creates a 1/8 torus section using existing 1-4cyli, 1-4cyls, 1-4cyl2 dat files.

There has been some discussion of the torus primitives on the Lugnet site. I believe the way we are going to handle these are by establishing ALL torii will have a Major diameter of 1(one) LDU, with the tube radius changing.
(The tube radius should never be over 0.9999 ldu.)

The Blue circles in the pictures are the Major radius and the Red circles are the Tube radius.

(Torus pieces shown in transparent blue are for reference only.)

Filename format so far looks like;
(It may still change some.)
tNNxFFFF
t stands for Torus
NN = sweep, number of segments 04=4/16 or 4/48. (1/4 shown)
x = "i"(inside),"o"(outside), "q"(quarter?{i,-i,o,-o})
FFFF = Size of the Tube Radius(Red rings)
Ex: 3333 = 0.3333(1/3), 5000 = 0.5(1/2)

Here is a list of suggested files to be generated. Most of them are fractions such as:
1/10(.1000), 1/9(.1111), 1/8(.1250), 1/7(.1429), 1/6(.1667), 1/5(.2000), 2/9(.2222), 1/4(.2500), 2/7(.2857), 3/10(.3000), 1/3(.3333), 3/8(.3750), 2/5(.4000), 3/7(.4286), 4/9(.4444), 1/2(.5000), etc.
