I also would like a tickbox option to force the numerical value be opposite of the object that’s measured.
Two other important requests for V9:
- This one was requested numerous times for years (since Rhino 6 was the latest version), and my super huge hope is that it will be finally added to Rhino 9, because it’s annoying to write ti manually countless of times daily.
- Add a “Flip” button (like the one used in “Loft”) for the “Blend surface” tool. Currently, the lack of that particular option forces the user to cancel the command and redo the picking of all input surface edges all over again. Manually flipping the handle ends returns the following error message in the Command line:
"Shape ends are out of order
BlendSrf failed to make a surface."
Having that option should improve the workflow, because it will let the users window-select the input surface edges and then flip the direction if necessary. Window selection for “Blend surface” is very useful for tiny edges (including when using the “Chain edges” mode) as the user will not be forced to zoom-in the camera too close to be able to pick an edge that appears too small on the screen.
