Can’t move point on green access when in front view

I have created a 2D line [curve) )in Top view. If I move to a 3-D view, select the line and select an individual point, I can use the green arrow to move the point in the green axis direction. However I can’t assess the required shape in the 3-D view, I need to be in Front view. When I repeat the process in Font view, as soon as I click the green arrow it disappears and I can’t move the point. I have tried many times and I am confident that I’m not just simply missing the arrow when I try to move. Am I doing something wrong?

@Murray,

Thank you for reporting about it.

I’m trying to reproduce this on my end, but it works as accepted. Can you please send us a photo/video of what you’re seeing?

Thanks,

I have uploaded a video. It starts by showing the type of shape I’m trying to achieve. There is probably a better way of achieving the shape, please let me know if this is the case. Regardless I’m still interested to find out if it’s possible to constrain point movement to an axis.
