Hi, how do I create a truss column, like the image. Thanks!

I've been able to recreate the truss column you have shown here in well under 5 minutes. Without dimensions or anything steel sizes I took my best shot at guessing, and assumed dimensions of 5' between chords and infill @ 45 degrees.

Here are the steps I took;

1) Using the column tool, draw your left chord (channel toeing inward) at the desired height.
2) With the left chord highlighted; right click>copy special> mirror. You will be prompted to pick the plane you wish to mirror about; select the handles of the column along the heel, then hit copy.
- this will mirror the left hand chord (producing the right hand, inward toeing, channel). You should now have two channels b2b, simply move them (using move special> linear) to the desired distance apart (in my case 5').

Now that you have two parallel channels;
4) Use the beam tool to draw a channel (toe down) that connects the two parallel chords.
5) With the top beam highlighted; right click> copy special> rotate. When prompted to select the point about which you would like to rotate, select the right hand grip/handle of the beam. Use the right hand rule to determine rotation direction and sign convention and insert the desired rotational amount, then hit copy.
- this will allow you to create the first, downward sloping, inner truss member (infill).
6) Using the extend marco (available on the tekla extranet for free) extend the infil to the left hand chord.
7) With the first, downward sloping, inner truss member highlighted, right click> copy special> rotate, selecting the bottom (lefthand) grip/handle as your point of rotation. Then copy at 90 degrees. This will create a sideways "V" shape of infill steel. Hang on because here comes the truss emoji, l

8) Copy the sideways "V" assembly downward as necessary using your copy method of choice.

Voila you have a truss column... hopefully. Assuming my step by step instructions are good enough to follow you should end up with something like I have shown in my picture. However, if my instructions were terrible and you were unable to follow them, I'm sorry, i tried my best. Writing instructions isnt my strongsuit, so please excuse any literary or grammar issues, afterall I ARE an engineer ; )

Goodluck. Feel free to comment back with any questions.

so after 3 failed attempts (which for whatever reason i cannot delete my posts) i figured out why my text was being cut off. I had to post it as plain text not an html file. Sorry about that Marceu. Either way hope this helps.
