Drawing size w/ distance |
|
|
I've drawn a large house, a small breezeway, and a garage almost as big as the house; however, the breezeway and garage are set back from the house and none is equal in height. How do I compute Scales to more accurately present a visualization of the three elements? In other words, right now all three elements - house, breezeway, and garage - are presented as though they'd been drawn on a wall; whereas, I know that visually the farther back from the house, the relatively smaller the other two elements. What methodology may I apply to give some perspective to this drawing?

Is this a 2D drawing, or a 3D model?

If drawn in 2D, the "traditional" practice is to NOT use "forced perspective" which is what I think you're trying to attempt. Just leave the "behind" elements at their true size.
If this were drawn in 3d and set up in AutoCad properly, "scaling down" would occur naturally as part of setting up perspective views. You didn't do this drawing in 3D, did you?

No sir, I did not do this one in 3D....at least not yet.
As an inquiring mind, how does "forced perspective" work? Siimply a scale-down based on angles of view to different heights at different distances, applying 100% or equivalent to the nearest? Or something else?

Not very well. Why not just follow tradition and leave everything at 1:1.
It's called an "elevation."

Sorry to be so late w/repsonse.
First of all, it's best to follow tradition as Mr. Turvill suggests. This is what people are used to seeing so it you wish to have your drawing understood, the traditional way is recommended.
"Forced Perspective" is a technique used to give the illusion of greater distance in a limited amount of space and is usually only effective when used in display dioramas with real objects. Museum displays use this technique when the desire is to create the illusion of greater distances in a limited front to back distance. It also usually works best when objects are already scaled down from their actual size.
Probably shouldn't have mentioned it because it really isn't effective in 2D elevation drawings as both Mr. Turvill and I have suggested. |
