1 point perspective and 2 points perspective

Here's the task:

 

The figure in 3D:

 

What I've done so far:

I'm stuck at this stage.

Two days and no responses? Let's give this thread a *bump* and see what happens.

Some of you architectural types need to help here. But I will start off, just to see if I can help a little. In the 2-pt, it appears you are confusing the projection of the two blocks. The blue line on the right should be coming off the back right corner of the large block, rather than from that of the shorter block.

I once used this tutorial to design a simple logo for someone. I had enough CAD experience though none whatsoever with drawing in perspective. I found it easy to understand and follow and the result was perfect.

[BillyWonka]

I used that tutorial too but thanks anyway.

Any good tutorials for one-point perspective? I have no idea how to connect those lines. It's such a mess I'm lost.

How do I draw the little box?

[ReMark]

You must have access to a good mechanical drafting book. I'm positive perspectives are covered.

See if these help you...

I did 1-pp drawing but it looks very odd. Can someone verify if it is OK or I made a mistake?

I still have trouble with 2-pp drawing.

I've tried various tutorials but I don't understand how to get that specific shape of the box in the middle. I'd really appreciate if someone helped me out with this one.

I was hoping some with real know-how would chime in here, and maybe they still will. I can't help you much, but I can tell you that, for projecting the tall box, including its notch, you need to project from the edges of the tall box, not from those of the short one. Try projecting using the edge points I've marked here.

The one point looks pretty good, you are missing one line on that inside corner.

 

For the two point, lower box, you have to find intersections and project lines from known intersections to find other intersections. See attached, hopefully it will help.

The file can't be opened:

Drawing file is not valid.

Is there anything I can do apart from getting a newer version of autocad?

Download DWG TrueView from Autodesk to convert DWG to an older version.

2004 version attached.

That is a very good presentation rkent. Remember at school you had to mention all the points. Yesterday went back to my technical drawing file to find some clues to work out the true perspective on a cone.

Extent of my knowledge is drawing simple ISO diagrams for fuel and conduit piping. When changing your viewpoint reset your UCS, then when your done UCS > World will set it back.

 

hope that helps?
