In this exercise, you will create line section drawings for your building (Assignment 205). You will also perform clay renderings or hybrid clay renderings as background imagery for your line drawings.
Part 1: Cutting Sections
- Open your Day or Night Interior/Exterior rendering file for Assignment 205.
- Note: Before creating the section outlined below, use File>Save As to create a new version of your work. Some operations in this technique cause irreversible changes to your model and you will want to be able to jump back and continue changing your design with the original file.
- Create a large vertical plane that slices through your building where you wish to have a section view.
- Follow Rhinoceros 5.26 [SectionTools] to create a section/plan of your building that is coplanar with the plane you established in the step above. This operation will let you temporarily see the plan (useful for modeling, etc) but will not let you render the section in V-Ray. Make sure you select to fill the cut with solid as this will help in the steps below. Turn off the layer created by Rhino 5.26 [Section Tools] (for now).
- Follow V-Ray 8.22 [C-Thru] to create a cThru material or download the cThru material from the course website.
- Use the split command to split all of your house and objects with the vertical plane you created at the beginning of part 4. Assign the half of the split objects that you want to be invisible the c-Thru material that you created/loaded above.
- Turn on your section surfaces created above. Assign the layer a material as necessary. Create a saved, named view of your section. Render your section. (This will create a rendered version of your section to use a background)
Part 2: Make2d lines
- Enable the section by using the stview command. Show the section in your “Section” view.
- Use Rhino 5.35 [make2d] (as you did in Exercise 228 & 229) to create a 2d line drawing of your plan.
Use File>Export Selected to export an AutoCAD .dwg file of your building section.
Part 3: Clay Rendering
- Follow V-Ray 8.29 [clay rendering] to create a clay rendering of your section view.
- Note: You have two choices to show the section view. You can select all of the non-cThru material objects and assign them a basic white material (you’ll have to create it). This method will be the most accurate for light inside your building. Alternatively, you can select the objects that have the cThru material applied and type hide. This will exclude them from the clay rendering. With this method, you won’t have accurate lighting inside the building (sun coming through windows, etc.) but it can still look good and is easier.
Part 4: Assembly & Post
- Using the methods discussed in lecture, use Rhino, Adobe Illustrator or AutoCAD to assemble your line drawing and the background imagery.
- Post your final plan view to the course website by the end of class today. Use any extra time to catch up on missing work.
