Make 3D Rectangular Structural steel

[erichmeiritz]

I just started leaning CAD not long ago and I made a 3D piece of 2"x4" structural steel - By accident. Now i cant figure out how I did it! I started by drawing a rectangle with polyline 2 by 4 units. Then offset it .250 (For the steel wall thickness) and fillet the edges. Then i extruded it and made a perfect piece of pipe! But now i cant duplicate it, even knowing more now then i did then. Ill upload the file of what i made. PLEASE somebody tell me how to duplicate this!

Either extrude both polylines and SUBTRACT the inner extrusion from the outer one or use the PRESSPULL command on the space between the polylines.

Hi and Welcome to AutoDesk Forum,

Extrude and Presspull commands will make it... i hope it's clear for you.

Hi @erichmeiritz,

As others have mentioned, PressPull or Extrude are the likely features you want to use.

Please update your status if you need additional assistance or resources.
