perspective

[SIDRIX]

Hay again,

Can you help me please with one question?

I need to draw a perspective of a room with all the components in it (chairs, desks, closets …), I have a lot of stuff in the room, rally a lot of chairs and desks (it’s a class room), so I thought that in stead of drawing the perspective of the room in traditional way(by founding every point), I could make the room 3D, put everything in actual shape, size and number and get somehow a view that everything in the room I see in perspective (sorry about my English, I hope that with the word perspective you understand the same that me – that objects farther look smaller and closer look bigger). If I just take a regular 3D view then the objects are in the same size in front and in the back. And a condition in my perspective drawing is that the depth of the room is taken two times smaller (this one is hard to explain, I hope that people that read this get the point of what I mean).

I found that there is an option called dview, but it is werry complicated, maby somen one could me more simplyer explain what and how I should do! There is a drawing in attachment, there is a fragment of my room plan and a small 3D model how it will more or less look like. And the wiev point that I want to look from is in the middle of the front wall ( the wall where the door is)

If you draw everything in 3D, you can cheat using the FLATSHOT command. Here's what you do:

 

1. Orbit around and set the view you want.

2. Type PERSPECTIVE at the command line to toggle the view from orthographic to perspective.

3. Use the FLATSHOT command to take a 2D snapshot of the view. Uncheck the "Show Obscured Lines" options to keep lines behind objects hidden. The catch is the 3D objects must be solids. 3D Faces and meshes will not work.

 

See how that works for you.

If the end result is intended to be a 2d drawing that is a perspective of the model, one way to accomplish that is to use the DBXOUT command after you have established the desired view. Then use DBXIN to a new drawing

 

A word of caution: the resulting drawing's circles and arcs will consist of tiny line segments.

Which is exactly why FLATSHOT is the best method in my opinion. The DBXOUT/DBXIN method is a legacy procedure from the limited options years back. Definitely worth knowing though so I'm not trying to take away from your post even though it might seem otherwise.

No worries, you might notice I use pre 2000 (r14) so FLATSHOT is not an option for me. Again depending on the desired output yet another option is available. That is to simply capture a screen shot to a JPG image.
