CADD stands for Computer Aided Drafting and Design. The use of computers allows the user to quickly draw things that would be repetitive and time-consuming if created by hand, view multiple construction options and experiment with different finishes before actually building anything in real life. Autodesk says its AutoCAD software is "one of the world's leading 2D and 3D CAD design tools" and has become very common in the architecture, engineering and construction industries. Drawing cedar shake siding or roofing by hand is a good example of something that would be tedious work, but by using hatch objects in AutoCAD the process can be quick and simple. There are even custom hatch patterns available for free online and conveniently "any hatch pattern you find should work with any previous or future version of AutoCAD" says the DotSoft website.

- Moderately Easy
Open your drawing and use the "Layer" command to open the layer manager dialogue box or palette.
Create a new layer called "A-WALL-PATT," set the colour and line type as needed.
Double-click on the layer name to make it the current layer.
Close the layer manager and return to drawing.
Use the "Boundary" command to create a polyline within the area you specify.
Use the "Hatch" command to open the hatch manager dialogue box.
Use the drop-down menus to select the "AR-RSHKE" pattern and set the scale to 1.
Click the "Add/pick points" button and click within the polyline you just created.
Right-click and select the "Preview" option to see the hatch pattern.
Right-click again if you are satisfied with the pattern or hit the "Escape" button to return to the hatch manager dialogue box and repeat the process as needed.
Double-click on the hatch object to return to the hatch manager and select the "Add/pick points" button to continue adding additional spaces to be hatched.
Repeat steps 5 through 10 if you prefer to create separate hatch objects in each area you specify.
Tips and warnings
- Using this method the hatch should not be annotative. If you draw using the annotative scale then you should select the hatch objects and change that option in the "Properties" dialogue box.
- Use the "Units" command to verify that the drawing units are set to architectural, insertion units are set to inches, and precision is set to 1/256 inch.
- This simple process is one of several possible ways to create cedar shake patterns or similar objects in AutoCAD. Review the "Help" menu for further assistance and tutorials.
