Chartered Institute of Architectural Technologists getting on bit

Some of us from the Yorkshire Region attended a session by Prof Sam Allwinkle on what to do (or more accurately what the problem is) with the decline in numbers becoming associate and chartered members

VASARI and Zach Kron MIT students work

MIT students talking about how they recreated a Vasari model of the Gensler Shanghai Tower. Involved some complex parameter controlled geometry to recreate the spiraling tangentially connected curves of the outer form which taper upwards.

The first part of the session covers the Olympic Birdsnest and how to model the the structural frame related to Rhino and analyze with parameters varying the overall vertical and horizontal radii. Skip this the Shanghai tower is mush more interesting

Nested door with opening angle parameter

Start with a door opening and frame from template door.rft

Make sure the door frame is driven by ref planes especially the hinging point

Add a ref line and end-point lock to two intersecting planes (align tool - then hover-tab until the ref line end point displays and then lock

Add an angle dim to the ref line  and make this the opening angle param.

Create the door panel as Generic Model face based so that it is vertical to the template face with simple params for width, height and thickness.

Load the nested panel in, SET tool, select the ref line and tab through until the horiz ref plane displays. Select place on ref plane.

Hover over the ref line, spacebar until the door aligns (the nested family face will be the origin) and then select and move along until the panel edge snaps to the ref line hinge end point. Also align-select the ref line and lock.

The door should then flex properly with the angle param
