Yes this is the RapCAD website, although not much development is going on currently. The documentation is still available here

Is this still the rapcad website? I see a download link, but no serious documentation. Did this move, or is it more of a figure-it-out-yourself project?

Comment on How to write an operating system (Part 2) by Giles Bathgate

GRUB can load the kernel directly, either in ELF or a.out format. Have a read of Part 1 to see how to create an ELF executable that can be booted by grub.

how would you boot to this from grub? don’t you need an boot image for menu.lst?

Comment on RapCAD preview release by Giles Bathgate

Firstly no, this is not name calling. The point I was trying to make is that openscadpy combines the power of python into a language like openscad. Typically RapCAD and Openscad scripts are safe as they are mearly a scene descriptive languages, they have no power to modify files, implant viruses, steal passwords, or anything else that a python program could potentially do. Usually you would take an evaluated risk when using any python script, you might trust the author, or you might read over the scripts source to decide if its malicious or not. Since RapCAD and OpenSCAD are not general purpose programming languages the possibility to have a malicious intent within the script is not viable. The “script kiddy” in this post does not refer to a known person such as marius, clifford, or any of the authors of openscadpy for that matter, it refers to a malicious author of a python based scene description intended to be used with openscadpy.

Hi, I’m trying to decide whether to get my students working with openscad, your rapcad or openscadpy. I’m trying to figure out your comment saying that repcad is a “more secure option than downloading some script kiddies python script off of thingiverse”. What makes rapcad a more secure option than openscadpy? I’m just trying to figure out if that point is a consideration for us or if that was just an opportunity for a bit of name calling (which would seem strange since the script kiddies working on that seem to include Marius and Clifford, according to the project’s github checkins)

As of version 0.9.0 you can now just do:

cylinder(r=0.5,h=1,$fn=10);

I do intend adding support for special variables $fn $fs $fa as you would expect to find but this is not implemented yet. In the meantime you can use the following workaround. Simply create a cylinder bigger than you need and scale it down e.g:

/** @r radius @h height @f smoothness factor */
module Cylinder(r,h,f){
scale([1/f,1/f,1/f])cylinder(r=r*f,h=h*f);
}

Cylinder(0.5,1,10);
