Pointset Reconstruction Tools Rhino 5 Tutorials
Posted in HomeBy adminOn 19/11/17Sep 7, 2012 - 10 minPlease help, using Rhino 5. Jason@jasonfking.comPlus 3 years ago.
I want to make a terrain for my project in Autocad. I already have the situation plan. I will lift up each of my isohypses (red polylines that represent the slope of the terrain) by 1 meter. So each isohypse will be 1 meter higher than previous one. After this I can easily just use the 'loft' command, and this is how I get the 3d of my terrain. But I am wondering, how can I manage the road (streets) surfaces into this terrain? Because streets are flat, and they do not fit into my slope terrain, created by lofting the isohypses.
So how can I make the streets, to look like they are part of the terrain also? Here is the autocad image of my location: And here is what I ment about the streets and terrain relationship: P.S. The image links are correct. If for some reason, they won't load, here are the duplicate links, uploaded onto different image host: http://img34.imageshack.us/i/unled2q.jpg/. Hello George, As far as getting your road onto the terrain, I'd get the shape of the whole area done and then make a centerline of where you want the road to go. Take the line and project it onto the shape and then sweep1 a profile that looks something like this using the 'roadlike' switch of the command. That switch will make the profile stay parallel to the XY plane.

Thank you for the reply EHNisja**.** But I did not understand you. So, I need to make a terrain from my red isohypeses, by using the 'loft' command. Then make only an axis of all the road network. Then make a cross section of my road (I attached an image in this post).
Then use the 'sweep to rail 1' command to make my road network, from the cross section and the axis of the road network. Instead of choosing the 'Freeform' style, I need a 'Roadlike top'.
And then what? But I do not want to make my roads parrallel to XY plane.
I want them to go along with my terrain. Here you go, The red line is a planar curve that will be projected onto the green surface. The blue curve is that profile that I posted before. I then copied the blue set of curves to the projected centerline.
I then joined the lower pair of pair of lines with the center to make an inverted 'u' shape with was then swept using the roadlike switch. Then the upper lines to make two more sides to the road. I must not fear. Fear is the mind killer. Fear is the little death that brings total obliteration.

This will get you started on the creation of the road surface, many tweaks of patches and blends will make it more realistic. And finally a bit of texturing to top it off.

Frank Herbert, author of Dune. No need to apologize for not being in town. This is all your good will, and you are doing it for free.
So I need to wait, as long as you think it is necessary. Thank you for such a nice advice once again EHNisja. I definitive owe you a favor for all this.
But unfortunatelly eather I am doing somethin wrong, or my knowledge of Rhino is not enough. Do I need to trim the terrain surface from the lower 'u' road or from the upper lateral ones? Here is what I have done, I uploaded the file: Also I did not understand your last two replies. If you think that you already explained it to me, and that I am very lame Rhino user, I would understand. Thank you for everything. Hello George, I took a look at the file that you posted and I have a suggestion to make.
I would make the terrain by using the patch command. The results of the lofting are HUGE size wise and lead to unreal conditions of undercuts and folds in the surface. I used the patch command in this image with a 0.2 stiffness setting for the purpose of working with your data.
If you look at your roadway as it passes through the terrain you would use the red and gold surfaces to trim away the grey surfaces. BUT since there are folds in the grey surfaces you have nothing to trim the gold suface with.
You need to fix that first. The same holds true for trimming the blue surface. I must not fear. Fear is the mind killer.

I have been using Rhino for a very long time and think that others are at the same level when I explain something or that I give enough of a hint that the answer is just one click away. That is not the case here.
All of the work that I do in Rhino ether is made all in Rhino as NURBS or is NURBS output from high end modeling programs imported in for my design work on the patterns. So this is a new area of work that can be done in Rhino for me. I am using your data so that I can see what Autocad outputs and what Rhino can do with it. The plug-in, pointsetreconstruction, that David Rutten wrote is a mesh tool and it's VERY powerful. Mesh work in Rhino is one area that I still am learning about, so bear with me on this one.
The work flow for this image was: • make the road a bit longer so that it extends past the RED ISOs of your file. • sweep out the road suface.
• Raise the road 0.2 units in the Z-axis. This will help with the trimming of the curves.
• Trim all of the curves that pass over and under the roadway. • Group the curves into two groups, the ones in the top half and the ones in the bottom half. This will allow for easy picking later.
• Blank ALL objects from the screen. • Show only the top half curves. • Using the 'Delaunay' option of the plug-in I got the meshes shown. Play around with the different option and see what you get as a result and when you're happy with the results select complete. If you have never installed plug-ins, it's real easy. Efw2 File Format 2011 Hyundai here. This one has a toolbar with it, *.tb file, it goes into the: Documents and SettingsAll UsersApplication DataMcNeelRhinoceros4.0, folder.
And the file: PointSetReconstructionTools.rhp, is a 'drag and drop' onto an open Rhino window file. This will load it into Rhino and be there to use in this session and on each session there after. Give it a try and let us know how it goes! Eric I must not fear. Fear is the mind killer. Fear is the little death that brings total obliteration.

Thank you once again for the help Eric. I think I finaly understand you: I need to trim the red ISOs from the road, and then make the mesh using the ´´ plugin, right? As far as for the installing of the ´´, my Rhino SR8 did not recognized it automatically by coping the PointSetReconstructionTools.rhp into the Plugins folder. I even tried to make a separate folder in the Plugins folder and then copy the PointSetReconstructionTools.rhp into it. But still when Rhino loaded he did not gave me a message that a new plugin has been loaded.
I needed to install it from the Options- plugins. But it works now, and I already tried using the Delaunay command with success.
Hello George, To remove the unwanted mesh faces you can use the command:_ExtractMeshFaces from the Mesh tools dropdown menu. Then the standard delete function will work. As to why it does that, some questions are best left unasked. I must not fear. Fear is the mind killer.

Frank Herbert, author of Dune. On a side note, can Autocad output this data as splines or bezier curves? The reason that I ask is that it looks like the plug would work better at making the terrain if the curves were smoother. I took and rebuilt a small area of your curves and sent them through the plug-in and it seemed to 'know what to do with them'. The resulting mesh was smoother.
Your file size is still very large. What is this going to used for? I must not fear. Fear is the mind killer. Fear is the little death that brings total obliteration.

Thank you for the reply once again EHNisja. I tried using the _ExtractMeshFaces command, but for some reason, I can not delete the lower parts of the terrrain (the bottom ones). I do not know about export from Autocad.
I do not think so. If the lines are made as polyline, then they will be polylines when I export them. Maybe there is some plugin that can fix this, but I am not aware of it. You made a splines in Rhinceros, from my Autocad imported polylines?
And then used ´Pointset reconstruction´ and Delaunay command? This is what you ment when you said that 'The resulting mesh was smoother'? I do not know why the file is to big. I am going to use it as a basis for my architectural project. I want to export it as.3ds from Rhino and then import it into ArchiCAD. Hello George, I have not forgot about you. I just wanted for you to try and figure this one out by yourself.
One thing that will help out is to first make a sketch on some paper and then see what has to happen in your model to make it so. Looking at one of the intersections I see that they come together at different heights, there are a couple of different ways to fix this, I would make a square surface to represent the area of the interection and then match the incoming roads to it.
Then match the edges of the roads to the new path, this may take some trimming and adding of new surfaces. Your goal is to get them to look something like this. Then your filleting will have a better chance of success. Add your edge profiles and join them all into one polysurface and use the Solids tool of fillet edge. I must not fear.
