Hi Mitch,
I agree with the final create new curves and loft etc you suggest. That is my plan.
I also realise that with the points I have no way will best fit occur through all points.
As it is I have now tweaked the surface using control points and got a very good fit, which the patch command could have done with my suggestion of extra controls in a fraction of the time.
To get to that stage of creating decent frame curves I need to get sections through a surface where the actual frames inside occur. Then I will tweak them as if they were contours on a map etc and get equal spacing or whatever needed , but I need to establish if there is a smooth transition or not between frames and I know some parts are not a smooth transition so the surface best fit is required first. I am aware that some of the points will never be accomodated without denting a surface with pinch points.
A pretty fair fit would give me a surface I can then use Project to get my frame stations onto, then refine the curves.
I just need to refine this in some areas it will fit but not at the expense of messing up the surroundings which do fit.
My patch was very good in 80% of places but somewhat out e.g. along the fin edge, I needed the surface there to better fit the points to enable me to create the aerofoil section at the fin edge, an area where curvature is very important and not so open to my own designer eye and smooth curve approach.
I have just been using MoveUVN for a good 2 hrs pulling and pushing on some control points to get rid of a ridiculous bulge that was a few cm away from points on the side then also refine the fin edge, like some tailor repinning and repinning cloth until happy.
We really could do with a makeover and some extra controls âŚ
With my request for an extra control, I wished I could select the points and curves its badly missing, then tell it to better fit that area only, and drag a slider or two and see the surface come in to fit, another slider controlling the âbest fitâ curvature through these selected points, another slider controlling the transition and smoothness of this into the surrounding existing unedited fit.
Quicker than select a control point, try U V and N values, alter the value strength and so on until I get the fit I want. Dont do away with these, but add in my âselect points to better fit toâ option.
Which points inside, outside, and on surfaceâŚto better see these would be a godsend and speed things up no end !!!
As it is I have to keep rotating and trying to spot which control points control the surface where points sit within the surface. To have it show me in one colour the points outside, another colour points on the skin +/- a tolerance I have entered, and in another colour those inside the skin, that would be great. As it is I have no ready viewer of these three states. I tweak it until a square point half shows above the surface, but Rhino and the way it shows surfaces cant be relied on visually I find. One can refine the display at the expense of slowing up things I recall and I may still have it set to that better setting anyway. I dont recall where the cotrols that give best display are as I type this.
I wondered if I should create spheres to the tolerance I wish, lets say 1mm dia and have one per point, that way I could choose render and see which spheres showed up inside and then further pull the skin in on those areas.
Is there a command to make a sphere per point ? I havent time to go creating spheres for every point. In fact Block would be good for this, should I wish to alter their diameter !
HISTORYâŚ
I typed History and then selected Record History at foot of screen, dragged a U slider, but then dragging it a second time I noticed history was greyed out again. It seems to think the one slider move was it !
I would like it to show me the skin later as I drag as opposed to when I stop.
