This is a change over 2006, in that you define a material list ahead of time, and it 'sticks' if you will. With 2006 you had to always map your. Clicking on the Materials Browser (or typing RMAT) will open the Material Browser Palette (shown below). Now that you have your object (the cube) and a list of materials, you're ready to go.
Topics covered in this Lesson: Creating your own custom materials Once you start working with AutoCAD's default materials, you'll soon realize that you don't really have a large selection. What if you need a white stucco material for a wall? Or grass for the lawn, or brushed aluminum,. Well, you get the picture. What you need to do is create your own materials.
The first step is to locate an image that represents the material you want in your drawing. There are a number of sources available on the internet. Below are 3 samples you can try for this lesson.
Click on the images to download the samples. Metal Sample Brick Sample Wood Sample Pick on any of the images above and when the new window opens, right click on the large image and select 'Save image as.' And save it in a folder where you can find it easily.
Now start the MATERIALS command to open the Materials Palette. Look for the button shown in the red box above - this will let you create your own custom materials. I will take you through the simple process of creating a material from an image file and applying it to an an object in your drawing. Then you will learn how to modify the material.
The previous lesson will give you more information on the material to an object. To create a new material from one of the images from above (or another texture) open the materials palette and click New Material button. This will give you a droplist to select the type of material you are creating. Select New Generic Material and we'll use the metal image you downloaded at the top of the tutorial.
Next you'll see the palette for creating new materials. Click on the Information tab and fill in the three fields as shown below. Click on the Appearance tab and add your image by selecting in the box shown below. The will open up window so that you can navigate to the image's location.
Load the image and you'll see it shown in the window. For now we'll just use the default settings so that you can see how the material looks 'straight out of the box'.
Apply your new material to an object and see how it looks. Perform a render if you want a better view.
Your object might look a little different from what I show above, but it should be close. Now that you've seen your material in action, you can adjust some setting and see how it changes the appearance. If you move the slider for transparency for example, you'll see the changes live on your screen. Try some of the different settings to see what they do. You have endless possibilities to make your materials do exactly what you want it to do. Although the example above is very basic, it shows how you can quickly create some materials for a custom rendering.
Keep this in mind when you are just starting your rendering process or when you don't have any advanced materials to work with. You can edit the image you're using if you click on the small sample image in the palette. Create another new material like you did above.
Instead of editing the material, this time you will use on of the images you saved (from above) to create a more realistic material. A couple of things to look at here are the Brightness and Scale settings.

Adjust the brightness and you can darken your material easily. The one I use quite often is Scale. This allows me to quickly change how big the material appears on the objects.
This can be done using MAPMATERIALS, but it's also easy to do in this palette. The scale you use will depend upon two things: the size of you image (in pixels) and the size of your object. You'll have to play with this one to get it looking the way you want it. As a rule, larger image files are better as you can scale them down and retain clarity This is just an introduction to the world of creating new materials. If you have a photo editing program like Photoshop or (it's free), you will be able to adjust the image files to fit your needs.

For practice, here is good way to get graphics into your renderings. Draw an octagon ( POLYGON command) and turn it into a REGION. Then create a new material using this image of a and apply it to the region. You will most likely have to adjust map settings to make it look good (or use the scale to object option shown above). For even more fun, add a wooden pole to it and use 3DROTATE to make it stand up properly.
In this exercise, you will create a material list, which defines the quantity takeoff criteria and surfaces to compare during an earthworks analysis. A material list is required to generate either an earthworks volume report or a mass haul diagram. A material list specifies the existing ground and datum surface to compare, and is saved with the sample line properties. This exercise continues from. Create a material list. Open Earthworks-1.dwg, which is located in the.
The drawing opens, displaying three viewports. Click Analyze tab Volumes And Materials panel Compute Materials Find.
In the Select A Sample Line Group dialog box, specify the following parameters:. Select Alignment: Centerline (1). Select Sample Line Group: SLG-1. Click OK. The Compute Materials dialog box is displayed, showing a list of all items defined in the selected criteria.
Verify that the Quantity Takeoff Criteria field is set to Earthworks. In the table, expand the Surfaces item. This shows surfaces EG and Datum. Next, you will set the actual object names that define those surfaces. In the Object Name column, in the EG row, click. Select EG from the list.
In the Object Name column, in the Datum row, click. Select Corridor - (1) Datum from the list. In the Earthworks criteria settings, EG is set as the base surface and Datum is set as the Compare surface. The Object Name fields specify which object calls for both an EG surface as the base and a Datum surface as the comparison. These criteria can be used with multiple projects and corridors.
The Object Name fields in the Compute Materials dialog box define a specific surface and corridor surface to map to the names in the Earthworks criteria. The calculation is performed and a list of materials is stored with the sample line group properties. In the drawing, notice that the cut and fill areas in each section are shaded. Hover the cursor over the shaded areas to examine the information that is displayed. To continue this tutorial, go to.
