| axonometric drawings (def) & types |
|
Definition
| view of an object includine to picture plan in a way that 3 principal axes are foreshortened. isometric, dimetric, and trimetric. isometric uses 30 degrees. diametric, 2 axes equally foreshortened. trimetric, all axes are foreshortened. |
|
|
Term
|
Definition
| isometric drawing. uses 30 & 120 degrees. all lines drawing from the turned pciture plan are parallel (same as ortho (but the lines are oblique (angled)). vertical axis is vertical, and horizontals at 30 degrees. lines of projection are equal to the picture plane **ALL AXES ARE DRAWN TO SAME SCALE*** |
|
|
Term
|
Definition
oblique drawing. uses 30, 45 or 60 degrees. like iso, locates endpoints through projection along the axes. advantage: can be used with a orthographic floor plan without redrawing ****3D VIEW BY TILTING FLOORPLAN*** |

Definition
| are the most accoruate of 3d drawings because they use convergence. one point created when alll vertical lines are drawing vertically, and all lines at the sight line are drawing horizontally. all lines drawn parallel to the line of sight converge at a vanishing point(s). |
|
|
Term
|
Definition
some key points about perspective: picture plane (PP): imaginary vertical plane on with all points of the obest are projected to creat a 2 d image. it can touch the back corner of the plan, or moved slightly forward (decrease) or back (increase) to alter the size of the perpective. moving it farther away from the picture plane will change the lines from the station point which widens the perspective |
|
|
Term
|
Definition
| step 2, after the PP is determined. 2 lines estedn from the station point to the left and right parallel to the 2 major sets of parellel lines. they determine the vanishing points, where they intersect the picture plane vertical lines are projected downward |

| what are the & in what portion of the development of presentation drawings do the constraints incorporated into a plan? |

Definition
#2 concept diagram is where the constraints come in
1. bubble diagram

Term
| presentation model vs. study model |
|
Definition
presentation model - detailed, accurate furniture, detail and finish respresentation. ususally done by a professional model builder due to complexity.
study model (aka working model) rough model used to aid in understanding 3 d aspects of a space. foarm core, chipboard, illustration board. 1/4 to 1/2" scale. may have some plan, color elements in it. |
