plane through three points

[SEIZMICdesign]

I just ran into this interesting behavior with creating a plane through three points: 

First I tried creating a plane through three points. Whoops! error! Whaaa?

Edit frature. Two points missing. Huh. OK. Reselect points:

Looks fine, save it:

Wait, what?

Oh, right off the end of some completely different line that has nothing to do with the points I clicked on. I get it now...

Anyone else experience this?

@SEIZMICdesign,

Are you able to share the model so that I can look into what is happening?  You can email me the archive file directly at mike.prom@autodesk.com

Also, why the HECK can't I make these points tangent to these lines?

hah, just noticed the line reference on the far left is wrong! That's what I get for zooming in too far...

You can make these profile edges adher to these points.

When creating the sketches for the loft (I assume) profiles use the Sketch->Project->Intersect command and select the straight lines. Intersection points will be "projected" where the lines pierce through the sketch plane. Then you can use these poinnts in your sketch. That also will keep things patrametric within reason. Changes in distance between the lines for example will update the profiles so they stay attached to the lines and the lofts should update.

@SEIZMICdesign,

Thank you for sharing your model with me.  I was able to edit the plane that you were having an issue with and select the missing point.  As far as making points tangent to the lines, points in theory are not able to be tangent to a line.  However you can make points coincident to a line, the best workflow it to project and then constrain.

Here is a link of repairing the plane.  I reset the points, that step wasn't needed, I just wanted to show another way to approach a solution.

I had tried basically the same thing only using the Construct -> Point At Edge And Plane method. For whatever reason, that was the incorrect method. Now I know!

I did day Tangent, didn't I? I meant Coincident. Thanks, sorry for the confusion. Also, I wound up just making a plane at an angle off that center line. Worked fine. I was just trying to be fancy I guess!
