How to Fill Colour in AutoCAD 3D?

Understanding the Hatch Command in AutoCAD

To fill color in AutoCAD, the primary tool utilized is the Hatch command. This feature allows for the application of colors, patterns, or textures to various objects within a drawing. Follow these steps to effectively use the Hatch command:

1. Open the Hatch Command: Begin by selecting the Hatch option in the Draw panel, typically found on the Home tab of the AutoCAD interface.

2. Choose Hatch Types: Within the Hatch Creation tab that appears, navigate to the Properties panel. Here, you can select your desired Hatch Type, such as a solid fill or a patterned hatch.

3. Select Your Color: Decide on the hatch color from the available options, ensuring it complements your design.

4. Define the Boundaries: You have the option to set boundaries for your hatch. Choose the “Pick Points” method to click inside the shape you want to fill, or you may opt for the “Select Boundary Objects” method to delineate the area you want to fill.

5. Finalize the Hatch: Once your boundaries are defined, press Enter to complete the hatch command and apply the fill.
