Fit Point Spline adjustment handle not able to be adjusted

[poporacer]

I created a sketch with a fit point spline and then did an offset with a couple lines to complete the sketch. I mirrored the sketch and then extruded the sketch. One of the handles appears to be locked and I can't adjust it. I do not see any constraints that would cause this action. Any suggestions?

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

I suspect a Thin Feature Extrude might be an easier solution.

In any case, the file would be needed to diagnose the spline handle issue.

Edit: And Mirror Feature (or Body) is usually a better technique than mirror of sketch (especially of spline geometry).

Thanks, here is the file and I will convert it to mirroring the body when I figure this out.

I was able to dimension your Spline Handles, but having said that, I would simplify the sketch and use Thin Feature Extrude.

See Attached file.

Edit: I also observed that you had unconnected points in your sketch.

Thanks a million. I wasn't dimensioning the Spline handles, I was trying to drag the handles. But when I tried to dimension the handle, I could set the length of the handle, but it looks like something else is constraining it when I try another dimension? Can you explain the pros and cons of using the Thin Feature extrude and when you should and shouldn't use it?

[poporacer]

And looking at your sketch, it looks like you didn't use the mirror but defined the entire sketch just making sure that your dimensioning is correct. Is that the better method?

Yes, I if you turn on Toggle Curvature Display of my sketch and your sketch - you will see the difference.

In general, usually best to NOT mirror Splines.

Thanks a million!
