Hello. When I select a curve and the control points turn on automatically, it works perfectly for editing all but the end control points. If I edit a mid-control point the line deselects and I can then grab any one I want. But if I got for a control point at the ends first, I have to click it twice otherwise the whole line gets dragged around. Any tips?
Iâd guess thatâs the default behaviour? Same with Rhino 8 macOS.
Only when selecting a curve, and then immediately selecting the 1st CV (Rhino unfortunately does not graphically reveal what is the 1st CV of a curve like in some other software), the entire curve is transformed, not the CV.
When I select any other CV but the 1st one, the tooltip prompts âPointâ. When I select the 1st CV, the tooltip prompts âEndâ (I only have âOsnapâ and âGumballâ selected in âModeling aids > Cursor tool tipsâ).
When you select the 1st CV with SHIFT + CTRL (command for macOS) pressed (sub-object selection), then you can also transform the 1st CV directly after selecting a curve (then, also the tooltip prompts âPointâ, not âEndâ).
Hi Adam -
Iâve tried that in both my customized scheme and a factory-default scheme and am not seeing that behavior here.

Youâre clicking on the point first, and transform it in a 2nd step; thatâs different.
Its a different behavior than Rhino 7
Hej -
In a complete new scheme to really ensure everything is at default settings:

Hi Wim,
I managed to reproduce the OPâs move behaviour. I was clicking randomly on the curve or individual points and seeing the behaviour you illustrate until suddenly I dragged and end point and the whole curve moved. Thereafter it did so repeatedly until it didnât and it went back to behaving like yours. Very frustratingly I canât identify anything to indicate what causes this.
I canât reproduce it at will, but I have done it three times, so there is definitely an issue there. Sorry I canât point to a reason.
Regards

Been playing around more and now Iâm seeing some of the variable behavior, works once and then doesnât work. I also noticed that it happens on control points near the curve, not just on the ends. Could it be that the control points are âbehindâ the curve. So sometimes you just get lucky and miss the curve when selecting the control point.
I went back to Rhino 7 and couldnât replicate the issue at all.
