Chunking down. Step 1

To start the digital model of The Harbin Opera House I traced the main curves on the plan and measured the angles of inclination of facades on the sections. The first base curve to offset is the external contour on the plan. The second base curve is the highest edge of the building.

There are several questions that have been generated during the modelling:

  1. All the offsets were done in Grasshopper by moving the curve dots and regulating the distance just by looking on the plan view. So, they are all approximate and don’t follow literally the curves on the plan drawing. Is where a way to make them accurate in accordance with the drawing?
  2. To generate the offset of multi curved contour it was divided on several simple curves. For each segment the Gaussian graph mapper was applied. But in some cases it is difficult to put the end point of a segment and the start point of the next segment in the same position. How to control this? Because some parts of loft planes are not joint. There is a gap between them. Or is there another way to make the offset?
  3. The segments of offset curves are not always conjugated smoothly. How to make smooth three dimensional conjugations?  
  4. The segments of offset curves are not always conjugated smoothly. How to make smooth three dimensional conjugations?  
  5. The maximum number of domain in the amplitude doesn’t match the highest point of the curve on the elevation/section. How to control the height of the curves?
  6. How much detailed should the model be? Should we do only the general shape, the structural part and the façade coverings or also the interior walls and stairs?

The next step to advance the model, I think, is to make solids of the general shape and then to create covering façade panels. Also we should model wireframes for the glass parts of the building. After that the wireframes can be used for discretization of glass pyramids.
