Arch materials

[rockn]

Hello, I would to know if you have problems with Material Editor ? Like it does not take modification you done in it.
Step to reproduce :
Create a new doc
Switch to Arch WB
Create a new Material
At the Edit panel clic the Material Editor button
Choose a material (like Steel-1C35) in the list of the MaterialEditor
Clic Ok (this close the MaterialEditor)
Python report the Material Object look like an empty material.

Code: Select all

>>> obj = App.getDocument("Sans_nom").getObject("Material")
>>> obj.Material
{'ProductURL': u'', 'StandardCode': u'', 'Name': u'Material', 'Description': u'', 'DiffuseColor': u'(0.5019607843137255, 0.5019607843137255, 0.5019607843137255)'}
>>>

We expect to get the new material

Code: Select all

>>> obj = App.getDocument("Sans_nom").getObject("Material")
>>> obj.Material
{'Density': u'7800 kg/m^3', 'UltimateStrain': u'21', 'ModulusOfShare': u'81000', 'UltimateTensileStrength': u'480', 'PoissonRatio': u'0.3', 'StandardCode': u'', 'Description': u'Non-alloy quality steel', 'YoungsModulus': u'210000 MPa', 'DiffuseColor': u'(0.5019607843137255, 0.5019607843137255, 0.5019607843137255)', 'Norm': u'EN 10083-1', 'Name': u'1C35', 'ThermalExpansionCoefficient': u'1.10E-005', 'Father': u'Metal', 'DescriptionPL': u'Wysokogatunkowa stal niestopowa', 'NameDE': u'C35', 'YieldStrength': u'300', 'MaterialNumber': u'1.0501', 'AuthorAndLicense': u'(c) 2014 M. M\xfcnch - GNU Lesser General Public License (LGPL)', 'CardName': u'1C35 - 1.0501 - EN 10083-1', 'KindOfMaterialDE': u'Verg\xfctungsstahl', 'KindOfMaterial': u'Heat-treatable steel', 'ProductURL': u''}

If you have the same problem, then this is a bug. You can try this branch, it fix the problem :

There was a bug there indeed, the material editor always returned None, no matter the clicked button. I fixed that in another form: git commit 2688a2f

Hi, I am testing the material editor.

I noted below and the blog about the colour characteristics but I can't get same effect.

I tested with an Structure object and shape colour e.g. set to blue, and set material to glass e.g. I search through the glass material with xxxxColour property and set it to gray e.g. But no colour change in the view. Anything wrong with my workflow???

- Colors specified in materials will override object colors
- If an Arch object has a material, its color is automatically taken from the material color.

Ok I just committed a first idea. Basically it works like this:

- All Arch objects now have a "BaseMaterial" property which is a PropertyLink and can link to a Material object
- There is a new "Add Material" button on the Arch toolbar
- When pressed, a new material is created, a task panel appears to load a material card and adjust some settings. You can also, from there, open the full editor from the Materials WB
- These materials are editable afterwards by double-clicking them in the tree
- These materials are always stored inside a "Materials" folder
- If you have arch objects selected when you create a new material, it will be automatically attributed to them. If not, you can attribute a material to an object simply by editing its BaseMaterial property.
- If an Arch object has a material, its color is automatically taken from the material color.

There is much space for improvement, but I thought this will already allow us to test and see how this kind of workflow behaves. Please test and tell me what you think!

Yes indeed. I look around everywhere, find the command below (thought it is only accessible from console only, before I finally note this is the button

import MaterialEditor
editor=MaterialEditor.MaterialEditor()
editor.show()

I should actually change that icon... It is not htere to paste, but to open the full material editor...

Hi, I am looking if, other than colour of shape and lines, material and texture could be applied and shown in the FreeCAD

Good morning @paullee:

FreeCAD support for materials and textures is in development. It will be more complete in the near future.

Through the GUI the options are a little bit limited. Using the python console and scripts you can do some things more.

Really FreeCAD has a big strength with materials and textures.

other than colour of shape and lines, material and texture

I think that you mentioned every concept (material and texture of surfaces, lines and points) used by lighting visualization and photo-realistic render programs. It doesn't exists any more, I think so ... am I loosing any thing?

Are you looking for a particular concept, or simply do you want to know every option?

The FreeCAD ability for rendering is very limited and I don't wait too much improvements in this question. I prefer to make geometries and materials in FreeCAD and later, if I need a nice rendering, to use a specialized program (at this moment it never happen). Perhaps a higher rendering quality could slow down the freecad operation.

See you

Thanks. I start learning FreeCAD recently and testing for a few aspects like webgl (viewtopic.php?f=9&t=3914&start=110) mainly for architecture or interior disciplines.

It is nice to have colours on the models - the example in FreeCAD is already nice indeed (copy below).

I think if FreeCAD could also provide simple texture and materials, no meaning raytracing, it is already very nice to deliver a good re-presentation of the model materials (e.g. wood, stone etc.). SketchUp is able to do that, but it do not have the strength of FreeCAD I think. I think FreeCAD is not Blender, again FreeCAD can built model, like buildings, that Blender is not good to do.

I'm in FreeCAD for this reason.
Blender seems to be the most popular option for a finishing touch of a model created with FreeCAD.
In my case, I am more physical and I don't need this workflow.
