Finally, I figured out how to manage curves and surface.
Now, I became better how can I model these things by many trials and errors.
At first, I hardly handle C-plane, section curves and axis. Then, I practiced these difficulties by making wings and scallops on the engine.
When I build the wing, I moved over to evry 4 views to set up right angle to Dreamliners’ curvy wing. I used section curves and points to get surface one by one. I experience many trial and errors especially this part. At last, I got the perfect figure to the wing, I was able to use every single surface and mesh tool on Rhino.
After that, I tried to trim the scallop-shaped engine part but it did not work. Therefore, I made curves and align 360 degrees to the exact size of the end of the engine. Then, dragged to the surface which I planned to cut off.
Finally, it did work!
These are line drawing of perspective view and surface analysis of the surface.
PH Kayak is an expedition ocean kayak often used for long sea fairing journeys. The kayak is made of two main parts that meet at a part line around the waist of the kayak. I chose to construct the kayak so that the two surfaces “Top” and “Hull” would be separate and meet at this part line or “Seam”.
I constructed these two surfaces by projecting and extruding drawn top and side curves referencing those views from PH’s website. These basic outline curves were extruded as surfaces and projected on to the extruded surface to intersect at the desired “Seam” curve.
By created a network of section curves coincident to Seam, Top, and Hull curves I could create two networked surfaces that got very close to the seam curve. Yet these two surfaces never actually touched. I then rebuilt the Top network of curves such that the resulting surface would intersect with the Hull surface by lowering it a couple of inches and extending the curves and rebuilding the surface.
The two intersecting surfaces could then be trimmed and additional surface treatment added such as a fillet or round at the “Seam” between the top and hull surface.
PH Kayaks have multiple storage areas required for long expeditions. I added these by drawing the openings as concentric circular curves in a top view Cplane then extruded them through the top surface. The intersecting surfaces were then used to Split the Top surface into the storage openings and the covers for the opening. The surface covers were offset from the Top surface and lofts were created between them. The same was done for the seating area but instead of a split, trim was used and then chamfered to reduce the sharp edges.
I forgot to mention the reading assignment at the end of class on Thursday. It is in the syllabus, but I thought a reminder might be in order.
The assignment is to read the chapter ‘In the Library of Form’ in Out of Control by Kevin Kelly. This work will introduce us to the concept of a multi-dimensional design space, or what Kelly calls a library. We’ll discuss it during the grasshopper workshop next week. Enjoy!
I’ve compiled a few online Rhino resources over the past week.
I find the video tutorials to be the most helpful when learning a new piece of software, and there are a ton of resources out there on the web. Here are a few good ones:
My colleague Jonatan referred me to digitaltoolbox.info today, which seems like a great resource. I haven’t seen any of these yet, but the site seems very comprehensive. If anyone has a look, let us know what you think in the comments.
Designreform.net has been around for years and has a wealth of video tutorials covering a very wide range of design software, including rhino and grasshopper. Mostly focused on GH and rhinoscript, but there are a few good rhino ones in there too.
Paramod.net is another favorite of mine. I haven’t seen the rhino tutorials, but I know that this guy is very thorough and clear. There seems to be a great range here including a couple of more specific topics like rendering and drawing output. Looks like good stuff.
On to the deep links. The Rhino wiki and resources pages on McNeel’s site are the most noteworthy, and are very deep indeed. The hidden secrets page is a little gem I just found today.
If anyone finds good Rhino resources out there, please share them in the comments. Happy modeling!
