Fusion is free cad software. It has built in text generation in the sketch meny. I will just show a very simple example of what you can do. Experimenting with it creatively can result in great artistic work.

1. Sketch some text.

Click on the sketch icon. choose a plane to work on. Click in the sketch meny again on the text icon to draw some text on the sketch you are doing .
Here is the letters for Steemit inserted in the text tool.

2. Extrude the text some arbitrary distance making it a solid.

I chose to extrude from the ground plane and downwards.

3. Put another sketch on the same groundplane as you did before.

This time go into the sketch meny and choose Project. Click on top of each letter and project the top surface of the letters onto the sketch.
Next hit the letter O, for Offset, or click on it in the meny. Offset each edge on each letter to a distance just outside the original letter. The letters e have "islands" in them and these has to be offset separately.

4. Extrude the offset sketch.

Now we have two solids (not true, each letter is a separate body), one for the smaller inner text and one for the larger outer text. Press A button for Appearance or find it in the meny. choose colors for the different parts as you choose.
Here is the outer bigger text bodies Blue. Inner smaller text bodies are white, AND the top surface of each letter is black. You can put an appearance on both a body and a surface.

5. Rise the inner text a small distance.

Switch to render enviroment and fiddle with settings for ligt direction, grond reflections, etc etc. hit render and the reult is like the top image.
Good luck!

The universe contains no anomalies and the appearance of an anomaly is a warning that our understanding is inadequate.
