How to add texture and material in AutoCAD 3D objects

In AutoCAD, we have a comprehensive library of materials and you can add material to any 3D solid object with a simple drag and drop.

You can also create your own custom materials in AutoCAD to give it a completely personalized appearance.

And if you like you can even make a complete photorealistic house with interior and exterior renderings.

Though you can apply materials to the entire object using default options there are some workarounds that you can use to apply materials to selected faces of 3D objects as well.

And in this article, we will explore all these methods of applying materials to objects and selected faces too.

Finding the material library

In this example, I will use this Oldham’s coupling 3D drawing to explain this method.

Switch to the 3D modeling workspace, you can do that by clicking the gear icon on the bottom right of the status bar and then selecting the 3D modeling option from the list.

Now go to the visualize tab and then click on the Materials Browser icon on the Materials panel.

The Materials Browser palette will open with a list of materials available for you which can be used in the drawing.

Now expand the panel on the left which says Home and you will get a categorized list of materials.

Clicking on a particular category from this panel will show only materials of that category in the Materials Browser palette.

For example, selecting Wood will show only wood materials in the palette as shown in the following image.

This will help you in sorting through the list of materials and in finding the right one easily.

This list is pretty comprehensive with lots of materials but if required you can also make your own custom material in AutoCAD.

Adding material to 3D solid

Now adding material is as easy as drag and drop.

Just find your material from this browser and drag the material and drop it on the object to which you want to add.

Alternatively, you can also select the object first and then right-click on the material you want to add from Materials Browser and then select Assign to Selection from right-click context menu.

After adding the material make sure your Visual style is set to “Realistic” and “Material/Texture On” is active

Adding Material to the Face of the Object

As you must have noticed here that the material is applied to the entire object by default and this method can be limiting sometimes when you only want to add material on any selected face.

For example, if you have a wall where you want to add different paints to the interior and exterior you can use this method.

Here I will use a simple rectangular 3D solid wall and I will apply Pink paint material to one side of the wall and Blue color to the other side.

The workflow will be a little different here.

In this case, once again go to the Materials Browser palette and find the materials that you want to add to the wall.

Select Paint from the material category and then hover your cursor on the Pink paint and click on the arrow as shown in the image below.

This will add the material to your active list of materials on the top of the Materials Browser palette.

Now right-click on the Pink material on the top of the palette and select Rename from the context menu and name it A.

Similarly, go to the Wall Paint category and add Cadet Blue color to the top of the Materials Browser palette by clicking the arrow as shown in the image above.

Rename this material to B.

In this case, I am asking you to rename the materials as it will simplify the process of adding the materials in upcoming steps.

Now we are all set to add Material A which is Pink and Material B which is Blue to different sides of the wall.

Type SOLIDEDIT on the command line and press enter then select Face from the options of the command line and then select mAterial from the next set of options.

Now AutoCAD will prompt you to select the faces, click on one of the faces and press enter.

Now command line will prompt you to type the name of the material you want to add to this face, just type A and press enter three times to exit the command.

You will notice that the material will now be added only to the selected face and since we already simplified the name of the material using a small name “A” you won’t need to type in the complete name of the material.

Once the material is added to the face you can rename it again to any name which is easy to remember.

Also, make sure the visual style is selected as “Realistic” and “Materials/textures On” is checked in the Materials panel.

Similarly, repeat the steps for another side of the wall but use material B this time.

Using texture map in AutoCAD

Using texture map in AutoCAD you can create materials that can be used in a variety of ways like adding  a logo on 3D object or making a cutout shape of people or trees.

You can also create custom materials in AutoCAD using texture map and add properties like surface texture, glossiness, transparency or even luminosity.

So, here I will make a custom material with a texture map and we will learn to apply it on 3D solid objects creating an effect of imprinted logo.

For explaining the steps I will use a cuboid and a sphere with transparent AutoCAD logo.

Type MAT on the command line to open materials browser palette.

Alternatively you can also click on the Materials Browser icon on Materials panel of Visualize tab in the 3D modeling workspace of AutoCAD.

From this palette select the default Global material then right click and select Duplicate from the contextual menu.

Double-click on the newly created material and provide a name in materials editor palette, I am naming it as Logo Material.

Expand the Generic tab if it is not already expanded and click on the image box, select the image which you want to use for the logo and click on Open button.

For this example, I am using SourceCAD classic logo with background transparency in PNG format.

For best results always use a PNG image with background transparency.

Double click on image box again to open the Texture Editor Palette.

Expand the Scale tab and change size in Horizontal and Vertical scale to the size of the logo which you want to see the object.

I have selected a scale of 5 units for both directions.

Also, make sure that None is selected in the Horizontal and Vertical drop-down menu of Repeat tab.

After creating the custom Logo material close Material editor palette.

Applying the material to object

To apply the newly created Logo material simply drag and drop it from materials browser to the object in the drawing area.

Also, make sure that visual style is selected as realistic to see the real-time effect of the material on the objects.

In the first instance, the logo might appear distorted but you can properly align it using material mapping feature, let’s start with cuboid.

Click on Box option from Material Mapping Flyout of Materials panel on the Visualize tab then select the cuboid from drawing area and press enter.

You will notice multiple arrow type grips in different directions along the box as shown in the image below.

Click on the grips and drag them in respective direction to properly place the logo.

Once you have placed the object properly press enter again to exit material mapping command.

Similarly, repeat the process for a spherical object.

It is not mandatory to use spherical material mapping option for spherical and other similar geometries.

You can create different effects by choosing heterogeneous material mapping options on geometries.

As an example, I have used the Box material mapping option on a spherical object shown below.

Summary

So these are some of the basic methods of adding material to any solid body or face and also adding images to faces using texture map.

There are also other ways of adding materials to a set of objects like applying the material to layers in AutoCAD which we have explored in detail in our AutoCAD 3D course.
