For example, besides being used as a Slab (for example, for a floor), you can add a Slab object and make it cover a wide area in the drawing and use Visio's Format Shape function to color it green for a vegetated area or brown for dirt. ![](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/036aff14-aaf4-47fd-95cb-41b6ad4ab4a8.png) Slab Options ![](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/image-1723113432556.png) The Slab options (accessed by double-clicking on the slab) has much the same settings as the Shape Date, but it will also include: **Layer Name** - When exported, the object will be assigned to these 3D export files. **Color** - Select what color that object will appear in the 3D view **Display unit** - The unit the measures are displayed in ## About Block Structures ![](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/62f25a72-472c-410c-9504-12db292ee4e8.png) ![](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/59594ad1-fc51-4c9a-95fd-22f66d8d11fb.png) Block Structures have all of the controls of a wall, but they do not respond when you click **Wall Scaffold** in the **Structures** tab. Block Structures do not perform the usual end clean-up functions, making them useful for designing Slabs, floors, columns, ducts, etc. You can enter a negative base elevation to a Block Structure to add sunken elements to a drawing, like a swimming pool. By entering a higher than ground-level base elevation, you can use Block Structures to indicate elevated drawing elements, like balconies. ![](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/477a6bba-aeb8-4396-abaa-5973094e8610.png) Block Structure Options ![](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/image-1723113466995.png) The Block Structure options (accessed by double-clicking on the Block Structure) has much the same settings as the Shape Date, but it will also include: **Layer Name** - When exported, the object will be assigned to these 3D export files. **Color** - Select what color that object will appear in the 3D view **Display unit** - The unit the measures are displayed in. ## About Spheres ![](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/a08e6531-fc13-496e-b5e5-d401a79d902c.png) ![](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/8f7fb428-63f1-42c5-922f-f9782e6affbd.png) On the drawing page, a Sphere is a circle that has a gradient fill. You can increase or decrease its outside diameter. You can also elevate it, to create (for example) an elevated water tank. ![](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/36099e29-6706-43e1-b567-da1c33b41d91.png) Sphere Options ![](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/image-1723113487713.png) The Sphere Options options (accessed by double-clicking on the Sphere Options) has much the same settings as the Shape Date, but it will also include: **Layer Name** - When exported, the object will be assigned to these 3D export files. **Color** - Select what color that object will appear in the 3D view **Display unit** - The unit the measures are displayed in. ## Domes ![](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/734aa2c8-96f1-4ff7-9684-c23dfd838972.png) ![](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/9c510da1-8020-4a3d-bd2e-ce943ee3a55d.png) On the drawing page, a Dome is half a circle that has a gradient fill. You can increase or decrease its base diameter and height. You can change its direction: horizontal, vertical up and vertical down. You can also elevate it. ![](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/f51abc6b-f55f-4cf7-833c-05ebca2bb4db.png) Dome Options ![](https://cdn.document360.io/ae69c864-58f0-4711-91e1-d1c2f7dff95f/Images/Documentation/image-1723113495305.png) The Dome Options options (accessed by double-clicking on the Dome Options) has much the same settings as the Shape Date, but it will also include: **Layer Name** - When exported, the object will be assigned to these 3D export files. **Color** - Select what color that object will appear in the 3D view **Display unit** - The unit the measures are displayed in.
