StCAD is open source

askoh

Hi:

I have just open source StCAD (MIT license) which has the code for freeCAD.
http://askoh.com/stcad
Although written in VisualWorks Smalltalk, I hope Pharo users will port it
in part or whole.

All the best,
Aik-Siong Koh

What is 'StCAD'?

'StCAD' is a basic 3D CAD framework in Smalltalk (VisualWorks 8.x). It
extends
the GF/ST 2D drawing framework into 3D. It also include 'StCAD-Geo' which is
the 3D geometric domain, 'StCAD-Math' which provides the mathematical
support
for 3D CAD and motion simulation computations, and 'StCAD-Doc' which is a
simple word processor. 'StCAD-Math' is also suitable for engineering,
scientific and business computing. The parcels are open source using MIT
License. Users can use these parcels with other private software to create
3D
applications like motion simulation, finite element analysis, CAD,
scientific
visualization, etc.

'StCAD' allows users to create and manipulate assemblies, which are
collections of 3D parts. The parts are 3D solids, which can be connected by
joints, constraints, contacts, actuators, springs, dampers or forces. The
parts and connections define the structure or mechanism that the assembly is
meant to represent. Animation is possible, if the user can provide time
series
of position and orientation data for the parts.

Users can also obtain output data in the form of plots and tables. XY plots
can be zoomed and set to equal scales. Data series available include linear
and angular displacements, velocities, accelerations and other user
generated
data.

'StCAD' has been used to create a freeware called 'freeCAD' which is a 3D
CAD
with Motion Simulation. For more information visit:

Thanks a lot.

BTW, the page at [1] looks really good for a graphical software. Maybe
some of its looks could be put in the CAD software repos, just to give a
glimpse of what is possible with FreeCAD and StCAD.

Excellent !

(BTW, I have problem opening your website).

It will be hard to port to pharo ?
The main difficulty is to have an equivalent for GF/ST 2D ?

Cheers,

Cedrick

Hi:

I have been careful to separate the GUI, Geometry, Multibody Dynamics and
Math. Only the GUI would need customization for Pharo. The others use pretty
generic Smalltalk. I suspect the GUI bits from Jun4Pharo, Woden and Croquet
should be sufficient for StCAD port. StCAD uses a bit of Jun and a bit of
GF/ST and a bit of Business Graphics Kit. I am willing to help anyone
starting the port. It can be the basis of a CAD system.

All the best,
Aik-Siong Koh
