3D Structural Mechanics Sketch

[mhfzsajid]

Hello, I'm trying to draw this T beam structure and the grey axis plane. I'm new to illustrator so I would appreciate any help!!

You could use the 3D classic effects with an isometric preset and then rotate it in place.Assign a shading of none and expand the appearance. Then add gradients.

Use the pen tool for the place.

If you are looking for exact construction, search for isometric tutorials.

Hi, how do I add the grey axis plane?

[Monika Gause]

That is just 4 clicks with the pen tool.

I'm very new to this app. I would be very grateful if you could show me how to make the extra diagram 🙏

Please start with the Help files that teach you how to use the application.

I have made the 3D shape using 3D classics but I can't figure out to change the color of the border lines?

You need to expand the Appearance: Object > Expand appearance. Then you can use this geometry and apply the shading you need.

Here's an example that uses a different design: https://youtu.be/SD1HARFrszs
