Fillet Command using ellipse radius rather than circle radius?

[WireTechLLC]

Good Morning,

I'm using AutoCAD LT 2018 and For some reason when I use my fillet command it uses the radius of an ellipse, rather than the radius of a circle..  I'm not sure what I did to change this.. 

I've searched through the forums and AutoCAD help and can't find a solution.  Does anyone have any idea on how to change it back?

I suspect your view direction is not from straight above.  The grip in the middle of the curve is characteristic of an Arc, not an Ellipse.  Type PLAN and accept <Current> as the default.  Or, you may need to set the UCS to match the Arc first [UCS, OBject option].  It could be caused by one of the Lines not lying flat in the current drawing plane -- pick each and look at its Properties for a non-zero Delta Z value.

Kent,

the PLAN command was already set for <current> so re-selecting that didn't change anything .  I tried changing the view to TOP up in the views tab, and that didn't change anything either.

I drew some new lines on a different layer, and for some reason those fillet just fine.. so maybe it's an issue with the other layers?

Kent,

I looked at the Delta Z for my lines and it looks like they're set for about 5.5  How can i change this so I only draw in X and Y?

Thanks!

HI,

i agree with @Kent1Cooper ... please if it's not fixed attache here your issue as a CAD dwg for testing.

If you didn't mean to be drawing out of the XY plane, for things already drawn, you can use FLATTEN to force them into it.  Or if it's all a matter of Lines, you can use QSELECT to grab all Lines in the drawing, and in the Properties box, set the Z coordinate of all their start and end points to zero, all at once.  For things not yet drawn, you can set the OSNAPZ System Variable [in new-enough versions] so that if something you Object-Snap to when drawing happens to be at some non-zero elevation, it will ignore its Z coordinate and use the zero-elevation version of that location.  That won't prevent certain other ways that you could get things off the plane, but it should prevent most accidental ones.

Kent,

It looks like that was the issue. 

Thanks for all of your help. I really appreciate it 🙂
