I am using 2015 Pro.
Having selected for example a line the offset button remains greyed out on all relevant tool bars.

"Offset" seems not to be available except in Wireframe mode, and sometimes not even then in my installation. It comes back to life if I switch back-and-forth several times between Wireframe and Hidden Line modes.

...But if you want to "offset" a straight line, the Parallel Line tool might be better.

Thanks Henry.
In my instance the Graphic on Path icon (whatever that does), which is next to the Offset icon on my RH drop down (or more accurately drop sideways) menu, appears to be permanently selected.  It remains in full colour whether I have selected an item to offset or not.

Can it be that you are in HL rendermode and have "Non Rendable" checked in your HL rendermode, then it will be very easy to believe you are in wireframe, but actually are in HL and the offset tool will not work/ is greyed out.

I am not sure, but i think to remember that TC is like this by default, in case i remember correct, that is stupid of devolpment
Yeah, just check it, if i open a New drawing with factory settings, HL have it checked, so it is stupid.

I think that simply means that the tool can be used, not that it has been selected for use.

What is it that you are trying to offset? It could be that the object is not available for offset. As I recall, offset works only on 2D objects. If there isn't any object that can be offset, then the tool will be unavailable.

Thanks for your suggestions, but Henry's solution that offset is only available in wireframe, but not in hidden lines, seems to have solved my problem.

My "offset" would not work either. However, when I went to "wireframe" it would activate, before it was grayed out. However, now I can highlight "offset" and highlight the graphic (a 2-d circle)(it circle turns left) I can see the "offset distance" in the window. However, when I put an offset distance in the box nothing happens. I've tried several times, but nothing happens. Any suggestions?
Thanks! CM

Now, I can highlight "offset" and then highlight the graphic (a 2-d circle)(the circle turns RED, indicating it is highlighted. I can see the "offset distance" in the window, but when I put an offset distance in the box, nothing happens. I've tried several times, but nothing ever happens. Any suggestions?

After you input an "Offset Distance", did you click inside or outside the circle? The Status Bar (bottom left) should say "Specify point on side to offset".

And how many "sets" do you use, it should be minimum 2
