I’m assuming there must be a way to do this that I don’t know about… Right now I end up making a centerpoint using areacentroid and rotating or using the gumball, but it would be nice if I could just a FromCenterpoint option nested within the Rotate command.

Does the following do anything for you? def RotateAboutCtrInteractive(): objs=rs.GetObjects("Select objects to rotate",preselect=True,select=True) if not objs: return cplane=rs.ViewCPlane() bb=rs.BoundingBox(objs,cplane) if bb: ctr=(bb[0]+bb[6])/2 ctr=rs.Xfo…

Select the object Get the area centroid or volume centroid rotate Not sure how the script detects the centroid enter the angle delete the centroid

Right, the getting the centroid part is where I’m stuck too. I’m not sure how to do this with a macro

A python script might be more flexible.

Hi @pdfaze Here is a script that does what you are asking. Copy and place the text below on an icon or run from the macro editor. The second line in the script is very useful as it auto creates a point at the gumball center so can be used with other scripts. One caveat is that object must be prese…

This the command but will only work when the object is preselected. RM [image] 3dsynergy: _SetRedrawOff _CPlane _Gumball _Point 0 _CPlane _Undo _SetRedrawOn

Hi RM, Thanks for this script and for your help! Is there are a way using the script to auto-input the centerpoint for the rotate command? Ideally i’d like the workflow to be: Select the object (or have it pre-selected) Run the script Rotate command begins using the centerpoint as the first input…

What I would imagine the script would be is something like Rotate (some command that automatically-enters the centerpoint of the object)

Hi @pdfaze [image] Pdfaze: the reason for wanting to streamline this so much is that when I’m doing this I’m often rotating and adjusting a lot of objects and want it the drawing experience to be very fluid. Yes I can understand your request. Try this new script it also deletes the centroid…

Hi @dale Sorry to bother you. If I create a box and use the above script Rhino correctly finds the area center in perspective and top view but does not in front and right views. Is this a bug or am I doing something wrong? I would expect if perspective view finds the correct center why is right and…
