ORTHO & Intersection Snap?

[tzframpton]

I usually am a Polar guy, not an Ortho guy. A job I'm on right now allows me to completely utilize Ortho but there's one quirk.... it seems when Ortho is enabled, the Intersection Snap becomes non-usable.

 

Been testing a few things for the past ten minutes and cannot figure it out. Any ideas on this? What am I missing?

 

Thanks!

I almost always use Ortho and I have never had a problem with Intersection. Do you have Otrack running? I don't use running osnaps much so try turning that off and setting intersection each time as a test.

 

Wait, what are you doing working in AutoCAD?

It is probably the Auto snap tracking. I have had problems with it in the same way. Ortho and snap tracking don't get along with each other.

Ha, I only use Revit for BIM. 20% of my work is still 2D shop drawings, which is AutoCAD work. My 2D setup in AutoCAD is WAY fast for creating non-3D, non-BIM mechanical HVAC and piping/plumbing layouts. AutoCAD, with the addition of LISP routines, is still king of the 2D realm.

I tried Otrack enabled/disabled, still nothing. I turned off Osnaps altogether and still same thing. Here's a video of it in action... maybe this could shine a little light on it?

Thanks again for the help rkent.

I can repeat your issue here, but I never run into it because I have perp set to F2 and just reach up and hit that without looking.

So you're using Perpendicular versus Intersection? Intersection usually works better for me for connecting at a 30 or 45 deg angle, for single lined wye fittings. I guess in this case Perp could be used... I'll try and reprogram my mind to use Perpendicular in this scenario.

 

Thanks again rkent.

Maybe your example video was too simple because you showed a line coming at an angle of 0 to the rectangle. But now you mention 30 or 45 deg angles which wouldn't work with Ortho (baring rotating the UCS) so I am not sure of the exact need.

 

Remember if you have an object to acquire a point for starting the tracking from, then Ortho works as expected, but picking a point and then moving towards the object won't work with otrack.

Yes, this is true... imagine if the line I was intersection with was already at an angle.

Gotcha. This makes sense, and answers my question. Like I mentioned before, on the example I linked you earlier, I'll just use Perp Osnap instead. Sometimes I just get lazy with my Osnaps and expect them to "just work" when I sometimes need to consider an alternative Osnap.
