I am a beginner, and to make things worse I just switched from Mac to Windows and it’s confusing me.
I have designed a boat and I have sectioned the hull into a number of panels. I want to profile foam blocks into male molds using a CNC router.
The panels, however, have compound curves so I want to situate them in a way that uses the least amount of foam. I have, with some success followed the curvy surface with a plane which I then offset and use to split the extruded panel.
I then have one flat surface which I align to world top plane. I don’t think I am doing it right??
Also world top plane switches on me every time I change view port, very aggravating, didn’t do this to me on Mac. When I unchecked Named Views Set C Plane, the C Plane remains correct but when I switch to say Front or Left Views, I am able to pan, tilt etc as if I was in perspective mode, is that right?
I don’t have a cam package yet, not sure if that would simplify this.
I knew there had to be an easier way to do it ) … I only have 12" Z axis cutting range on the CNC router I ordered but by roughly rotated the panel first then running BoundingBox I was able to minimize the Z height from 30 inches to around 8". Since I only need the face profile to shape my panel, I think this might work, thanks a lot!!!
It sounds like you have “Universal construction planes” activated (Options>Modeling Aids). Try going back to “Standard construction planes” and see if that helps.
You can also try this Python script for calculating a minimal bounding box around an object or group of objects. There is also a thread out there where people have brought this into Grassshopper and optimized it to make it faster - however this one just runs as a simple script in Rhino.
Oh interesting, I did not know about script use, I will learn how to use it. I tried switching to Standard Construction Planes, it does not help. As soon as I switch to another view, the plane changes again and when I switch back to perspective it’s no longer at World Top.
Edit: I just tried that script, it’s perfect!!! Thank you so much!
Really? That’s very odd. It shouldn’t do that at all when Standard construction planes are enabled, each viewport should keep its current CPlane until you specifically set a new one there.
Only other thing I could think of - do you have OneView enabled?
Just type OneView - look at the command line. I think it automatically sets it to enabled when you do that, click the command line option once to set it to No, then Enter. Don’t know if that will change anything, doesn’t seem like what you’re seeing.
Ok, I tried that but it didn’t work. This is incredibly disorienting, I can’t even tell if my part is right side up … the CPlane Changes every time I switch views and when I come back to perspective I have to reset it to World Top, this can’t be right, I wonder if it’s a bug? I am using Windows 10 pro.
Using a different approach is their a way to orient the bounding box and panel to the proper spot without using the Grid? Right now I create two lines and use Orient 2 points twice (more than once) to get it to line up … and then of course the cplane changes on me so I don’t know where I am lol )
Thanks very much for your help, I realize I am probably doing something stupid, just works so different than on the Mac
In that aspect it shouldn’t be different at all. I’ve never seen CPlanes change that way unless Universal CPlanes are active and even then it should not behave as you describe. Something is wrong there, but I have no idea where the problem might be… Do you have the latest Rhino SR (14) installed? Can you run SystemInfo in Rhino and post the results here?
I would use Orient3Pt once. As reference points choose one corner of your bounding box that you want to go to the origin and the second and third points along the edges you want to be aligned with the X and Y axis. Then as target points, type 0 for the origin, anywhere along the X-axis for the second point and anywhere along the Y axis for the third point (having Ortho on will make this easy).
Thanks Helvetosaur - I will try 3 point now … Looks like I am on SR13 Edit: I just updated but that didn’t change anything. I also am using a Space Mouse, wonder if that has anything to do with it… The 3 point process works perfect, Thanks!!
It definitely might. Can you temporarily disable the space mouse plug-in in Options>Plugins (uncheck the box, then close and restart Rhino). Then try with a normal mouse for a bit and see if it works more or less correctly?
Don’t throw it away just yet… It should work correctly without doing that - unfortunately I don’t have one of those guys, just an ordinary old 3 button mouse. But there are some people in here that do, maybe post a new topic under hardware section of this forum with the title of ‘Space mouse problem’ or something like that, describe the symptoms and reference this topic, and maybe someone will know exactly what to do. It might just be one of the settings in the driver somewhere that you can change. Good luck…
I downloaded the most recent drivers, now it mostly works. When I switch from perspective to any other view, the C Plane does not move on me, it’s just when I switch back to perspective, I have to set it to World Top again. At least the other view ports don’t behave as I am in perspective.
If it bugs me too much I will sell it, I was doing fine with a regular cad mouse before this. )
