Project 002 Dirigible

September 24, 2007

a jpeg image of the dirigible model

I chose page 180 paragraph 1 and built a model of the dirigible. The paragraph describes the size and basic structure of the dirigible, and I built this model based on that description. The command I used most was making a cylinder and scaling the edges of its top and bottom with soft selection. The gas bag, gondola, and the body of the engines were made in this way.

The passage says that the engines are turboprops and they are driven by solar panels. This is a little confusing because usually a turboprop rotates its propeller by its jet engine. I interpreted this that this dirigible has two types of engines: the main engines at the wingtips are turboprops and are mainly used when the dirigible accelerates, and the sub engines under the gondola are driven by solar panels and are used when the dirigible cruises at constant and relatively low speed.

Area 5 SketchUp models of Capital City Grill & Shaw Center Phase 2

This building is a restaurant located at the north-west corner of Area 5. It contains a cafe called PJ’s at the north-west corner of it. The official website is:

This building is Shaw Center Phase 2, located on the south-east corner of Area 5. The part with black facades are already in use, but the other part is not used now, and the construction has not begun yet.

When I was making the facade textures of the buildings, taking nice photos was difficult because the street were narrow and many trees and cars were in front of it. So first I scewed the photos perspectively and then copied and pasted some parts of them again and again to get good facade textures. On site I measured the length of the sides of the buildings by counting the number of paving materials such as bricks and joints of concrete, and when those units were not available I paced them off. When I was modeling the basic structures of the buildings, I made a hierarchy of groups, like one group contained some groups and then each of those subordinate groups contained some other groups.  This prevented each part of the whole model from sticking to each other and made it easy to manage them when I changed them later.

a tip for reducing the file size in SketchUp

September 9, 2007

I found how to remove a imported texture.

>window>materials>select>in model>choose the imported texture by right click>left click> delete

deleting a surface which has the imported texture on it is not enough. The texture still remains in the file and the file size remains the same. So if we want to remove the texture in order to reduce the file size, we have to do as I said above.
