I have asked questions about this quite a few years ago and had hoped there were improvements since rhino 4 in rhino 6>
I have also seen other people mention 2d digitising on the forum.
i think it would be great if it was handled well within Rhino there are many people digitising on these tablets.
I have created a short screen capture video explaining this issue, see below.
I stuck a bit of masking tape to my Digitiser board with 7 off X’s on it, you can see the points being captured i then zoom in and run the capture again and as you can see the second set of point are at a different scale even though they are exactly the same set of points.
they are also in a different position to the others?
My digitiser is quite large at approximately 1500mm x 1100mm and is very accurate but if i digitise a large object with detail it gets harder to see and would be great if i could zoom in and out to have a look at the digitised points etc…
ideally what would be great is if we could set the bottom left point of the digitiser board to absolute datum in Rhino and then all points or lines / curves etc… digitised in positive X and positive Y or to the right and up from the triad datum.
or if when digitising we could initially digitise the 4 corners of the board to set the working area.
and regardless of zoom or mouse movement in rhino it will always track from absolute datum accurately via the digitiser puck
this is also 2d so it needs locking in the top view port.
or if zoom not possible something like a “lock screen” option so whilst digitising the view port is fixed and can’t move.
ideally we need a 1 to 1 absolute digitised input as that would really work well. however as long as the digitise points were proportional the scale doesn’t matter as the finished digitising can be re-scaled after to the correct scale. but 1 to 1 would be best.
at the moment accidental movement of the PC mouse can cause position issues and We need to trust the input as we will be creating parts from the data.
I hope the guys at Mcneel can see the use of this and be able to either say it will work in some way or make an update so it can work.
i am sure it can’t be that hard to sort as it is almost working…
I look forward to your reply.
