Hi all. I’m fairly new to Rhino. I seem to have turned on an option where every time I try to draw a curve, I can only place my next vertex at a point rotated 90 degrees from my previous one. This’d be great if all I wanted to draw was stairs but it’s not ideal for my current project. How can I turn this off? I don’t think it’s something to do with accidentally having grid snap on - they always snap at exactly 90, 180, 270 or 360 degrees from the original vertex and never to any other points on the grid.
You have Ortho turned on.
You can click the Ortho tool in the Status bar to turn it off,
Or you can press and hold the Shift key to temporarily suspend the Ortho effect.
Consider going through some of the Getting Started tutorials.
Use of Ortho, Grid Snap, etc. are important to easily controlling Rhino.
Have a look at the Learn page.
I have ortho off, snap off and yet when I enter points with a line shown between the points, whenever I hit a 90 degree point relative to the last point entered, there is a slight jump to the 90-degree angle. I get around this by zooming up even more so the jump-to-90-sensitive-zone is far enough away I can finally pick the point I want. How can I turn off this feature? Or is it a Windows thing?
All off and it does it. I will try to post a script tomorrow that demos this. It is not a restrictive type of snap, any angle can still be achieved. But it like a gentle magnetic attraction that kicks in when the angle is less than a fraction of a degree away from 90. So you cannot set 89.9 for example.
I looked at this more closely and what is actually happening is that the line that trails after the square selector with cross can snap to the left or right of the center-edge of the square where it should stay. The command I am executing is:
pts = rs.GetPoints(True, message1="Pick points on center of trees around whole block:")
So you have to learn to ignore the line’s alignment to the square selector popping around and focus on centering the square on the spot that you want to select. Sort of nerve wracking. Even after doing this a couple of hundred times I still find it very distracting especially in comparison to how well I get the rest of Rhino to work with my Python script for processing 3D models made from drone photos.
