I wondered about this. Is there a way to lock (like with SHIFT key or something) the tangent, perp., etc. before I click?

These first two are good examples from the top view.






I started with the triangle shape to get the proper angles.



I then copied the lines twice -z axis.



I added some guide lines and made a connecting circle with tangent (trimmed it later).



Then I made a couple of circles, rotated them to line up with the big triangle, and trimmed them.



...after adding the rest I noticed the errors and started over. Keep in mind, this was an incomplete first draft so it looks awful. I was able to make corrections and finish the shape.

Forgive my simple descriptions. I am a hobbyist and not familiar with the terminology of 3D programs. If I don't make sense, please let me know and I'll try to clarify.

Hi propmaster,

Sorry no there isn't anything like that - if you're getting unwanted snap points that are very close to the actual one you want the main ways to avoid that is to either turn off the types of snaps that are getting in the way, or hiding some of the objects that are not involved with what you're currently doing, or also just zooming in a ways which will then give more space between the different available snaps and decrease the chance that you accidentally target the wrong one. And also like I mentioned before paying attention to what the snap label is saying is pretty important too - if you want to target an end for example but you're seeing the tag say "perp", that's when you would want to zoom in a ways so you could get more space between those 2 snap points.

Thanks for posting the overview of what you did - I'll try to follow that but I'm not sure if it's quite specific enough for me to reproduce what happened, it would be easier for me to understand what's going on if I had just 2 curves and a specific snap to do.
