Yes and a lot more commands I presume (continues todo).
Would be nice if we had a person who wants to describe the commands.
We could use these descriptions for developing, testing and a user manual.
I personally prefer a all command user interface as in AutoCAD (but
not a AutoCAD clone written in python).

Some external definition file which the user can define?

Better in what way?
Adding layers, setting layer properties?
Mimic of AutoCAD layers?

Correct.

To what?
Paper, pdf, raster files?
Do we need a plot manager or just plot the current visible area?

A pen?
Is it not better to use the line weights on screen and on the plot.
Than we can produce color plots.

Dear Gertwin;

Offset Command :
I am not very gr8 at OOP and have bit of difficulty
understanding the total structure of PythonCAD.
I will help on writing the descriptions of newer
commands, till we find further help.

Linetype:
If some external file can help it would be highly
customizable and we and ship few standard lib
along with pythoncad.

Better Layer management:
- on/off of layer
- default color and linetype of layer. (currently all the layers
other than current are having same color)
- freezing of layer (currently all the layers other than
current are frozen)

Print:
to PDF will be always useful we can focus on high end
plotter/printer later

Pen asignment:
I am more used to managing print with line color
since changing lineweight of every object at later
date when we decide to take print on different size
of paper becomes difficult. But using entities lineweight
can also help.

Hi Yagnesh,

Matteo and I also had difficulties to understand the PythonCAD code, this  
(and performance) initiated the restructuring.

I agree with you on layer management.

We can also use the new cairo draw functions for plotting.
Just a thought:
Maybe we can define a special layer for plot layout (something like paper  
space).
On this plot layout the user can define multiple viewports with a different  
visual portion of the model/image/scene.

Pen assignment sounds like using a pen plotter and plotting with hpgl.
I don't know there exists such back end for cairo.

Regards,
Gertwin
