rouan Posted January 23 Share Posted January 23 Hello, I would like some help to do an impossible work for me. I have a 2D top view and a 2D front view. I would like to create a surface with a texture with those to forms. I try many differents things without succes. Could you help me and show me how to to? Thank you so much. Top view and front view.vwx Quote Link to comment
Pat Stanford Posted January 23 Share Posted January 23 I don't think anyone will be able to help you based on your current description of what you want. Tell us more about what you are trying to do. I can imagine at least four different desired outcomes from those two shapes. Quote Link to comment
rouan Posted January 24 Author Share Posted January 24 I would like to do something like this. This one is a Nurbs Courbe but I cannot put a texture. It's to represent a set for a show. it will be a fabric glued to a piece of plastic. Quote Link to comment

Pat Stanford Posted January 24 Share Posted January 24 Since you have the curves, try the Model:3D Powerpack:Create Surface From Curves option. Then use the Shell Solid tool to "extrude" the surface and give it thickness. The curves will need to have 100% coincident end points for this to work. Quote Link to comment
Popular Post Benson Shaw Posted January 26 Popular Post Share Posted January 26 (edited) I would do this with the Loft tool, 1st mode (Loft Surface, No Rail). Then Shell Draw the layer plane curve with Polyline tool, Bezier or Cubic Spline mode. Use fewest possible vertices to achieve the curve. Modify>Convert>Convert to NURBS, or draw with the NURBS curve tool. Duplicate then Move 3d x=0, y=0, z=4390mm Reshape tool>Constrain z mode. Drag the vertices up/down as needed for desired curve. Side views are helpful for this. Loft Surface>No Rail (1st mode). Click endpoint of low curve, then click endpoint of top curve, then click the green checkmark icon in the mode bar. Result is a NURBS Surface. Add fill color and texture (or texture later) Shell tool>set desired thickness. Hover/Click to highlight the surface. Click the green checkmark. -B Edited January 26 by Benson Shaw Don't stop on my 5 Quote Link to comment
Jonathan Pickup Posted January 26 Share Posted January 26 I agreee with Benson, i tried another way, but Benson's way is easy and straightforward. Quote Link to comment
rouan Posted January 26 Author Share Posted January 26 Benson, thank you. I think it's the easier way to do. Thank you very much 1 Quote Link to comment
rouan Posted January 27 Author Share Posted January 27 Hello, I'm back. I tried your solution but I have so many points on my nurbs that it's impossible to edit properly. Quote Link to comment
line-weight Posted January 27 Share Posted January 27 This kind of shape comes up quite often as a question. It can be hard to achieve both neatly and accurately. I think you need to try and redraw your curve with fewer points. Quote Link to comment

VIRTUALENVIRONS Posted January 27 Share Posted January 27 @rouan Yes, your curve is somewhat disjointed. I am going to do a small tutorial for you and post early this afternoon. How you build this curve is easy, but important for accuracy. Quote Link to comment
rouan Posted January 27 Author Share Posted January 27 Thank youuuuuuu. I build this curve with polyligne Bézier. Quote Link to comment
VIRTUALENVIRONS Posted January 27 Share Posted January 27 @rouan Besides tutorial, I enclosed a new file with curves and final model if it helps. I backed it up to VW2022 regards.... CURVE 2022.vwx 1 Quote Link to comment

Steve S. Posted January 28 Share Posted January 28 (edited) @rouan I am curious to know it you are looking for a spiral shape such as this The spiral was made with a helix tool. So I think it will probably have a smoother shape than trying to drag around bezier handles. The flat spiral at the base (outer side) is 4401mm. So it is 1mm over what you show in the original post The overall height is 4413mm. So this is 23mm over what you show in the original post. The thickness of the wall is 101mm FOR THE MOVIE AT THE BOTTOM, MAKE SURE TO PRESS THE RESIZE BUTTON SHOWN BELOW UNTIL I CAN FIGURE OUT HOW TO MAKE A SMALLER SIZE MOVIE Spiral with viewpoints 2.mov Edited January 28 by Steve S. 1 Quote Link to comment
VIRTUALENVIRONS Posted January 28 Share Posted January 28 @Steve S. He posted his file up about six posts. it shows what he is trying to accomplish. Good method you have shown. I never use deform tools for various reasons, but I always like to see how people use them. Quote Link to comment

Steve S. Posted January 29 Share Posted January 29 (edited) @rouan So if you do decide to use a spiral for the plan view shape of your curved rake wall, then to dial in the shape, and length you want along that spiral, you're going to have to do a little bit of trial and error or number of iterations to get what you want. It’s a process that might take 5 or 10 minutes or maybe even longer to get that particular shape and length. In the video below, I begin the process by adjusting the START RADIUS. Later on in the video I dial in the END RADIUS. You could see in the video that I don’t move at the speed of light. I’m not a fast user of any interface now days. Would be terrible as a CAD draftsman. So as this is a realtime recording by a slow user, it is feasible for anybody to do this in the same length of time if not faster. Now even though I am slow at the keyboard and UI, I am still able to get a shape I like and a length of 14’-4” (along the spiral) in about 4-1/2 minutes Once I have that dialed in, in the dialog box for the Helix-Spiral, I would DESELECT the FLATTEN, and do as shown in the previous post video. All in all, the 2 stage process could take as little or less than 10 minutes to come up with a 3D model of a curved rake wall. The basic procedure in the below video is — Use the HELIX-SPIRAL tool UNGROUP to see the length UNDO and try again ITERATIVE PROCESS for SPIRAL.mov Edited January 29 by Steve S. 1 Quote Link to comment

VIRTUALENVIRONS Posted January 29 Share Posted January 29 (edited) Whenever I look at someone's problem I tend to answer, as to how they are doing it. They have a methodology in mind and it does not introduce noise. But, there are lots of ways to make this. In the video below, except for the initial flat curve, the new curve is made without being handled. All Object Info Palette. About 50 seconds to make the spiral curve.

Steve S. Posted January 29 Share Posted January 29 @VIRTUALENVIRONS Hi Paul, Yes there are definitely a number of ways to do this from looking at everything in this string. It’s hard for me to determine exactly what @rouan is looking for as I didn’t see a good plan view of the curve he wanted. It could be something that looks kind of like a spiral for all I know but is more or less, just a freehand curve of sorts. I don’t know the underpinnings of how the Helix-Spiral tool works. But to me, what I like about the tool is it appears to be making a beautiful Logarithmic Spiral. Whatever it is, it is something that I would personally find time consuming to try and make by dragging handles. In my case I figure, leave it up to the computer to do what computers do better than me. https://archive.lib.msu.edu/crcmath/math/math/l/l383.htm Quote Link to comment
VIRTUALENVIRONS Posted January 29 Share Posted January 29 Hi Steve, I don't think it was an exact mathematical spiral. The original curve was quite disjointed. They should be able to make it now. You showed some nice work above, although I never use deform tools, except in animation. That is where their real strength is. Deform tools tend to be the end of the line and that seldom works for me. 1 Quote Link to comment
Steve S. Posted January 29 Share Posted January 29 @VIRTUALENVIRONS Thanks Paul, Your videos are always great to watch. I agree with you on deform. It really is not something I am going to use very much either as in the case of what I did above. It really was a freehand way of going about it. Bend on top of bend with no coordinates typed in, blah blah. You know what I mean. No precision with that example. But, it was the first thing that popped into my mind, so I went with it. LOL The second method was something I played with first in Plasticity, and then figured how to do it using Vectorworks. 1 Quote Link to comment
