hi all,

I'm doing a little project designing a house I'd eventually like to
build.... I'm trying to do it all with freeware...

I've pretty much decided to use designworkshop lite for the basic plans, it
seems to do the job nicely.

I've played around with Moray (3.3), and POVRay, and very happy with it:
gives the sort of rendering quality I'm looking for (I wanted radiance and
raytraced reflections etc).

I can get a model in DXF format from design workshop lite to Moray using an
old program called "Crossroads" to generate a raw file from the DXF, then
importing to Moray using the standard RAW import.

I tried 3ds win, but can't get the plugin to import DXF directly (it just
shows RAW in the list of files and even that doesn't work - Moray
crashes!).

But the problem now is material assignment: I can't assign different
materials to different surfaces - only 1 material for the whole model which
is not very useful!!!

Any thoughts on how I could do this?

Any suggestions helpful, even alternative software (freeware modelling /
rendering) which might do the same job.

Cheers

Leon

I think the problem is in the dxf format. I never use it so I'm no expert. I
think it is just one mesh for the whole of your model. You can import it by
layer or by colour using 3DWin (the standalone programme not the Moray plugin).
Or in designworkshop lite save the plans in separate meshes after you are happy
with it. For example Room1_Wall1.dxf, Room1_Wall2.dxf, etc  then assign
materials to each mesh.

In terms of alternative software, try Amabilis 3D Canvas. Its DXF import 
will correctly differentiate each sub object. This is one thing that 
irritated my too about a lot of programs. "I don't bloody care if it is 
all on the same layer morons, it clearly has hand, finger 1-4, thumb, 
wrist, etc. in the file, why the hell are you converting it to a single 
overlapping mesh with degenerate triangles.", was a very common thought I 
had trying out various programs, ever since I figured out I could get 
free models. lol 3D Canvas is the only one I have found that not only 
correctly separates them, but generally shows them in wire frame as 
different and visually unique objects.

Note however that I have not actually tried the export to .pov yet, so I 
can't say for sure if it correctly outputs the result as more than one 
mesh. Also, unless there is a plugin around for some format that Moray 
uses (I haven't looked around to see), then as far as I know you can only 
just get a .pov file from it. However, the mere fact that you can 
manipulate each piece independently is a definite bonus over all the 
other bone headed programs that assume that every other program you plan 
to use it with will render degenerate triangles instead of throwing them 
out. I blame the prevalence of OpenGL an DirectX modellers/renderers for 
this kind of stupidity. ;) lol

Hi all,

many thanks for your thoughts.

I gave amabilis a go, and indeed it does import DXF as separate objects
fine. However, now I can see the DXF a bit more clearly, I can see a number
of problems with using the DXF anyway (normals are flipped, model is not as
"clean" as I would like).

So I think I shall give Moray a go for the modelling itself, and hope to
find someway of producing the plan / elevation drawings later from the
Moray model.

I think I can get the separate materials for different faces with careful
use of CSG's, but just out of interest, do you know if Moray 3.5 lets you
assign different materials by face?

Thanks again,

Leon

hi all,

just fyi: not sure this is the place to say this though!

I think I'm going to go with the following software for my project, based on
a good few hours going through tutorials etc on many different bits of
software....

1. Base design: DesignWorshop Lite
2. Material assignment, furniture etc: Blender. An annoying interface at
first, but I'm beginning to like it.
3. Rendering: Virtualight. Seems to be quite good...

Just out of interest, has anyone got any thoughts on this?

cheers
