Workshop 5 Notes COMPUTER AIDED ARCHITECTURAL DESIGN Workshop 5 Notes, Week of September 30, 2013 Projection With Surface and Solid Editing, plus Delaunay Mesh and Height Field Digital Terrain Modeling PART I: SURFACE EDITING 1. Surface Generation with Control Points - Select the tool to create planar Surface from four rows of four points from the surfaces palette - create the grid of four by four points and the surface is generated - alternatively, create a planar surface by two corner points, and use the command line 'rebuild surface' to rengenerate the surface with 4 x 4 control points: - Choose the control-points on tool and select the surface. With the 'ctrl' key selected ('ctrl' & 'shift' key on an Apple keyboard), select and elevate points to make wavy surface. Before after - view the surface with simple shading directly in the viewport - turn off the display of the control points, change the active layer and color ->draw a closed polyline shape on top of the planar surface - change the active layer and color ->draw a circle on top of the planar surface - change the active layer and color color ->draw a bSpline on top of the planar surface - grab all three elements and use the Move tool to reposition them to hover above the surface.

Recently many people at NewSchool have been asking me 'How can I create a 3D topo for my project' So I figure I would post a simple Rhino tutorial here to share the steps I go through in creating 3D terrains so that other students with the same question can see how I do it. It might not be the best way - but it definitley works for me. You can click on the following image links at anytime to make them bigger BEFORE YOU START: You need to make sure you have installed the pointset reconstruciton tools from the and that you have your CAD topography map with all it's topograpy lines placed at their correct elevation heights STEP-ONE Begin by entering the Delaunay (from the pointsetreconstruction tools) command.

Rhino will then ask you to select vertices for delaunay triangulation. You will then need to chose all you topography lines.You can leave the sample interval size at its default which is one Once the triangulation reaches 100% you can then right click on your mouse to complete the command. You will then be able to see that you have created a very colorful triangulated surface - which is not workable at all STEP -TWO This step requires you to switch to top view (will not work in other views). Once in top view you can enter the Drape command. Create a crossing window over the triangulated surface to define the area to drape. Leave all the drape options set to their defaults. Once the command is complete you can delete the colored triangulated surface.

This will give you a very cool looking topo that you can now use. This model is sometime a little difficult to work with - only because of its high amout of control points that are used to give the topo a higher precision finish form. (The image that follows shows the high amount of control points used to create this topo) STEP-THREE What I would do next is reduce the amount of control points by Using the Rebuild Command.

Which will pop up the rebuild Surface control Panel Within the control panel you will be able to see how many control points your surface currently has by looking at the point count. You can then reduce to a smaller amount of points. You can currently see that I have chosen to reduce to the amount of 50 (U) and 50 (V) point counts. Which gives a lower precision model -but a much easier model to work with and modify. That concludes this tutorial on how to create 3D topos Some people chose to use the plugin which works the same way as the pointset reconstruction tools plugin. Instead of using the delaunay comand you use the Rhinoterrain version which is RTdelaunay. You then follow all the same steps shown here (TWO & THREE) to create a workable 3d Terrain.

I hope this helps •.

DIVA - DIVA-for-Rhino is a sustainable design plug-in. Plug-in available for Rhino 4. Included in Rhino 5. Math – The Math Plug-In calculates smooth degree 3 curves and surfaces based on parametric equations. Pointset Reconstruction – PSR is the process of creating 'higher level' geometry from ordinary points. Tips & Tricks - 3D terrains. The pointset reconstruciton tools from the Rhino Labs and that you. The same way as the pointset reconstruction tools.
