I believe I started this exercise when creating my drawing for materiality sheet.
I opened one of my previous hand drawings in Adobe Fresco app and started drawing on top of it. Here is the process: (Fig. 1 – fig. 6)
As in this exercise I am meant to look at function and whether the size is big enough I had to work out my initial design into maximum dimensions required. So I looked at my brief again and worked out I would like the biggest circle diameter to be 3300mm which fits within 9m2. Then I worked out my head room in the doorway to be 2200mm in the tallest point. It is quite tall for the door but I need to have in mind that it will be lower to the sides.
I set maximum height at 5900mm giving me 100mm space just in case I later decide to create base for the pavilion.
I drew these dimensions in cad, including 200mm beam thickness for reference. I then saved it as a .jpg and imported to a drawing app on my iPad.
I drew and experimented with the front elevation view of my pavilion.
I even created one with background (by drawing over a photo of relevant view) and one with shadow (even though usual elevation drawings would not include it).
(Fig. 7 – fig. 26)
Then it was time to move to side elevation. (Fig. 27 – fig. 30)
It was really tricky as the top ‘ring’ is at an angle (I’ll let cad tell me later what angle this is) therefore it cannot be just flat rectangle in side view. The entrance was also really tricky. As I’m typing it up I can see that side view with entrance facing left contains quite a few errors. Such as the beam not reaching to ring in correct place and top ring positioning and angle in general.
That is something I’ll correct when completing technical drawing for my design.
I think I best work out details of that when drawing technical in cad later on.
After that I needed to workout my rings diameters. I already knew that the largest, middle ring will have external diameter of 3300mm and internal 2900mm.
I needed to work out other diameters.
I used the image of front elevation drawing with visible cad guidelines. I cropped it as close to external rectangle of guidelines and then inserted the image into cad. I then resized the image to fit into a 3300 x 5900mm box. From this point I was able to roughly (but still fairly accurately) work out my other rings diameters by drawing and measuring lines on them.
After that I was able to place the rings on my floor plan drawing.
I centred them in the same spot (for even weight distribution and stability of my structure).
I’m not sure if I should have pictured top ring (smallest one) as a slight oval because it’s angled. I find it really confusing.
I can use the similar way later in CAD (or even by hand) to work out the angles in my pavilion.
At this point I’m starting to think that it may be easier to build a model in cad (or perhaps real life model will help me enough) (Fig. 33)
Drawing the entrance in plan view has been quite tricky, a semi ring at an angle! I think oval represents it better (Fig. 34 – 35)
Fig. 34 – 35
The lowest ring (middle one on the plan) will be at knee level and will be the most space restricting feature. I worked out its internal diameter at approximately 1600mm. It took me a some time to work out if it is enough to move around. In the end I measured my outstretched arms span and it is almost the same. So I was able to imagine that it would be enough space at knee level for two people. The place will feel roomier than that as the diameter widens until it reaches 2900mm internally at the largest ring level which is way above average eye line. I am not sure if I should include any seating. Perhaps a small two person bench opposite the entrance (if any).
