Hi Tom, in moi.ini under the [Drawing Aids] section there is this setting:

[Drawing Aids]
<....>
DisableOnSrfInOrtho=y

If you set that to DisableOnSrfInOrtho=n then the first point that you pick in a drawing command will use "On srf" object snap in both Ortho and 3D views instead of only in 3D views.

There is an additional setting that controls how picked points after the initial one behave:

[Drawing Aids]
<....>
ProjectOsnapsInOrthoViews=y

By default that is turned on and it makes points picked in ortho views after the first point to be projected to a plane parallel to the view. That helps make things drawn in ortho views be planar.

You can turn that off by setting ProjectOsnapsInOrthoViews=n or also this one is in the Options UI under Options > Snaps > Object snap options > "Project to plane in ortho views" checkbox.

With both of those settings modified as described you will then be able to draw points snapped on to a sphere surface in both the 3D and Ortho views, but just be aware that things that you draw in the ortho view will not necessarily be planar to that view like they are with the default behavior.
