How to use CAD to make hollowed letters

Creating hollow letters in CAD (computer-aided design) software involves several steps, and the exact process may vary slightly depending on the specific CAD software you are using. Here’s a general guide on how to do it using popular CAD software like AutoCAD or SolidWorks:

Create text:

First create the text you want to hollow out. Most CAD software has a text tool that allows you to enter the desired text and adjust parameters such as font, size and style.
Convert text to geometric shapes (if needed):

Depending on the CAD software you use, the text you enter may be an actual text object or just a visual representation. If it’s the latter, you’ll need to convert the text into editable geometry.
For example, in AutoCAD you can use the Explode command to convert text into a single geometric shape.
Offset or squeeze text:

Once you have the text as a geometry, you need to offset or extrude it to give it thickness. This step creates the solid letters, which will be hollowed out later.
In AutoCAD you can use the Offset command or the Extrude command to achieve this.
Create a cavitated area:

Now you will create the areas that will be hollowed out from the letters. This can be done in different ways depending on the shape and complexity of the letters.
A common method is to draw enclosed shapes or areas within the letters where you wish to draw hollow areas.
Use Boolean operations:

After creating the empty regions, you will use Boolean operations to subtract the regions from the solid letters. This will effectively hollow out the letters.
In AutoCAD, you can use the “Subtract” or “SubtractSolid” command to perform Boolean operations.
Clean up (if necessary):

Depending on the complexity of the letters and the precision required, you may need to clear out any remaining unnecessary geometry or adjust the resulting empty letters as needed.
Verify and confirm:

After hollowing out the letters, verify that the result matches your requirements in terms of shape, size, and thickness. Make necessary adjustments.
Save your work to the desired file format.
Keep in mind that the specific commands and procedures may vary slightly depending on the CAD software you use, so be sure to consult your software’s documentation or help resources for detailed instructions tailored to your CAD tool.
