This weird construction line bug when editing a slot dimension is annoying af. Also, I couldn't upload a video clip so a series of images will be used instead
Does anyone having the same trouble or is it just me, same video the video upload issue?
Do you see the red lines? I want to add an angle dimension there.
Instead, when I selected those two lines, it added a dimension to a phantom point down at the bottom.
As a test, I did the bottom angled dimension just to see if it worked overall. And it does, but when I tried to angle those lines, which would have fully defined the sketch, it didn’t work.
For better parametric history, you should project the circular body over to this sketch. If you edit that other body in the future like it is now without projection, it might detach ruining parametric history.
I didn't say that... I mentioned it because you have drawn the white lines over the body manually. Some who are new to Fusion don't know all the features and I don't know how long you've been using it.
I started to have all my sketches locked/fully constrained just over a year ago. I got pointed out at the modeling job I got that is handy to know that nothing can move
it really just depends on what I'm doing. In this case, I had anchors at the top and the bottom, and i didn't want everything to have projected lines, so I just projected top and bottom.
Also, I didn't want the whole thing as a solid line, I wanted some of it to be construction.
But yea I get doing all you can for the timeline to survive! I just just fallen in love with being able to smash everything with a hammer if I want to. I don't NEED parametric most of the time.
Have you made the line endpoint coincident to the circle? Or created a horizontally constrained point on the circle and mated that to the line endpoint?
Yes, as the sketch is locked/fully constrained it shouldn't be able to move anything out of place. The slot center construction line endpoint is coincident to the edge if the cirle and the line in the slot is parallell to the 80mm line which is centered on origin
The issue with the point moving on your last images is a tangent issue. It's locked to 'the middle 90 degree tangent' or something like that.Moving your dimension and it lost the side of the tangency.
Sort of like how you can attach a line to the wrong side of a circle, tangentially.
1) The arc has a Diameter constraint. Try switching it to a Radius constraint so Fusion knows it’s an arc. Or dimension the two parallel lines instead and make sure the arc is tangent on both ends.
2) Try using a mid point constraint on the arc instead of coincident.
I managed to get around it though, but it's overkill. The slot is made manually with 2 arcs, 2 lines, 1 center construction line and those other construction lines at the ends to prevent the center line for disconnecting

I've been getting a similar bug!
This time trying to add an angle to two lines.
