Material Schedules and Custom Material Properties in Revit

Revit’s materials can be used to track finishes in a more formal way, such that they are used in the bidding documents. There are many challenges related to utilizing this workflow, but this post will focus on the mechanics of creating materials with all the information an architect or interior designer might want to tabulate.

The first thing to do is create any custom parameters. The trick here is that you are creating a parameter associated with materials, not a “material parameter” as shown in the image below.

If you create a material with Type of Material set to Material you can only select material names from a list. If you create a Text parameter associated with the material category, then you can type whatever you want in that text-based parameter. TIP: Add a tooltip to your custom parameters to help other designers in the office.

.

Accessing the custom material parameters is not very intuitive, but this does not really matter as…
all this information can be modified in a schedule. Notice how the “Paint” materials can be assigned to the “Paint” Class and then sorted by Class in the upper left – you can create custom Class groups (which is also accessible when using the Paint command).

Below is a Material Schedule using all the required built-in and custom parameters for paint. The big catch here is that only materials used somewhere in the project appear in this list… which is a good thing, right? Perhaps:)

If you ever want to be able to tag any of your ‘custom material’ information within the model, maybe in a presentation drawing for a more detailed client meeting, you have to make sure to use Shared Parameters. The image below is an interior elevation with a custom material tag applied to three different walls in a project. These can be selected and deleted or swapped with the simple material mark-only option.

Here is an example using/creating a shared parameter…

Finally, if would be really nice if the ‘custom material’ parameters were in-line with the information on the Identity tab.  I did a little image editing to show how I envision this looking in Revit (this os a separate tab). Having to click the little button to access ‘custom material’ parameters is not very clever. I will find, or create, a Revit Ideas on this and update the post later.

Single material rendering

20 Nov

An interesting workflow to make your Revit model render in a single material.

The rendering look like a hand made model fashioned out of wood.

In Revit is not possible, mainly because you can’t override materials with View Filters.

But that doesn’t mean you can’t do it with a workaround in a way that probably won’t hurt anything.

While View Filters don’t allow for material overrides, Phase Filters do.

Taking a look at Phases dialog box for the default Revit template, there is no default Phase Filter that has the New phase state set to overridden; and that makes sense because when do you want to override thew new work? You just want it to look like it normally does.

Create a new Phase Filter called Single Material and set the New phase state to “Overridden”.

Then for quick access, I went to the Graphic Overrides tab and opened the “Phase – New” material.

In the asset browser got me an appropriate material from the Autodesk material library.

Create a new material, replace the asset for the “Phase – New” material. Tweak the bump map, dialing the scale up if needed since If you wanted it to look like it shrunk.

Advances in Architectural Geometry – MIT – YouTube.

The MIT Center for Art, Science & Technology (CAST) and the MIT Department of Architecture co-sponsored a video that was featured at the “Advances in Architectural Geometry” symposium at the Centre Pompidou in Paris from September 27-30, 2012. Architectural geometry is an emerging field using geometrical principles to approach current design challenges with a renewed mathematical rigor. As part of a presentation on the most advanced and challenging research in the field, the video spotlights the groundbreaking technologies, materials, and processes produced at MIT.

Create Seamless Textures for Rendering and Visualizations

Create Your Own Seamless Textures for Rendering and Visualizations.

If you are not sure what I mean by “seamless” here are two examples…

This is a textures that is NOT seamless… Notice how you can see where the image repeats itself…

 

This is a seamless texture… Notice how you cannot tell where the image repeats itself…

The hardest part about finding good textures is finding ones that are seamless.  There are two ways to approach such a problem.  One is to find a texture online that is not seamless and make it seamless.  The other is to take a photo of the texture you want and make it seamless…  With either approach the following tutorial will teach you how to make a seamless texture from any image file…

The tutorial “Creating-custom-texture” from “Rendering with Revit”  Paul Aubin are more detailed and explained in the revit project.

Make the models in SketchUp and convert them to Revit. In the conversion process we make unique materials and layers so users may modify the color of the architectural entourage. To keep the file size small we individually export from SketchUp repeated parts and them copy/mirror the part with Revit.

(Update: We’ve posted a video showing the process)

http://www.youtube.com/watch?v=91z0hX3zfAc

Click the link to see the process to ensure that the materials come across nicely.

SketchUp

1)    Open file in SketchUp

2)    Save as another version as to not overwrite the original

3)    Explode model as many times as necessary to remove all nested groups and components

4)    Create a new appropriately named Layer for each Material Color

a. Materials in Revit are listed alphabetically, following the generic to specific will make it easier to find the material

b. Try to keep names short and descriptive

c. Give materials unique FF names due to Revit’s manner of not warning the user if a material name is already being used and just assigning the material properties of a same-named material already in the project file when loading a new family

5)    Separate the geometry by materials into the various named Layers

6)    Check the geometry in each of the layers by turning off all layers and then turning on and off each layer. Note that using ‘Select by Material’ some times gets incorrect geometry if the geometry has one material applied to a side and a different material to the opposite side

7)     Delete all materials in the model so that all geometry has the default material

8)    Verify that all the normals are facing out toward the camera. The polygon color should be the yellow-green color and not the blue color.

9)    Check Model Units : Take note of the set units

10)     Export to a dwg file giving it a unique name such as Mercedes_SLR_noColor, with the export options of AutoCAD 2000 and export faces only. Be sure to not include lines or the revit model will have lines even in shaded-only render mode.

Revit

1)    Create a new family selecting the appropriate family type, eg.: a car would be in the ‘entourage’ family (See the document title ‘Revit Family Designations’ for a few list)

2)    Import the dwg file with the following options:

a.     Colors: Black and White

b.     Import units: Select “inches”

c.    Positioning: Auto – Origin to Origin

d.     Place at: Leave as it is

3)    Click ‘OK’

4)    Once the model has loaded verify that it was automatically placed at the origi

5)    Click on Settings>>Object Styles

6)    Click on the “Imported Objects” tab

7)    Verify that the layers made it into Revit.

8)    Delete the 0 layer as its unnecessary

9)    Go to Materials Editing by clicking Settings>>Materials

10)    Delete all of the imported materials

11)    Create a new material for each SketchUp layer (color) by copying the “Default” material

12)    Name each material the same as the SketchUp layer (color) This makes it easy to know which goes with which when assigning the materials and when the family is in a large project file.

13)    Under the Graphics tab, click “Use Render Appearance for Shading”

14)    Click on the “Render Appearance” Tab

15)    Under the heading “Generic Material Properties” click the RBG button

16)    Enter the RGB color values — get these by looking at the original SketchUp model for each material

17)    Use  generic material to maintain a “SketchUp” look -or- pick an appropriate material for glass, metal, plastic and etc.

18)    Click apply and keep adding materials until finished

19)    Click OK to exit Materials

20)    Click on Settings>>Object Styles…

21)    Click on the “Imported Objects” tab

22)    Under the heading materials there should be no material listed for each of the imported layers

23)    Click on the Material cell for the first layer, then click on the ‘…’

24)     The Materials editing box comes u

25)    Select the appropriate material

26)    Click OK

27)    Do the above step #23 through #25 for each of the imported model layers

28)    Once all assigned, verify that each layer has the correct material assigned by making sure that the layer name and the material name are the same.

29)    Click OK in the Object Styles box when complete

30)    Save the model

Quality Assurance

1)    It’s always important to check to the model by loading into a project to verify the scale and how the materials render

2)    Click on the shading display button to verify that all the colors are correct

3)    Render a 3D view of the scene

4)    Verify that all of the materials render properly

5)    If they don’t render properly, return to the family file to see what is up

6)    To test again, load the test Revit project, Updating a family and re-loading it to a project does not update the materials that we’re previously imported. Since the material names are the same, the first materials imported will remain causing your fixed family to render improperly again.
