Somehow turning 2D elevation drawing into 3D model?!

Hi guys,

New here, 1st post and all but have a question.

Any way to turn a 2d elevation drawing of a building into a 3d model? Im guessing its proberly not very easy as there are no z values? Am i right in thinking that?

Cheers

There's not an "easy button" that does it, no. But you can use 2D linework to leverage 3D solid objects using some simple commands, such as EXTRUDE and PRESSPULL.

You can also draw walls very quickly using the polysolid command. It works just like the polyline command, only draws a solid the height and width you specify.

No i know, didnt think it would even be an easy job by any stretch BUT, how hard?

I've attached a drawing in process, im not wanting to 3d it all or even a whole face but if part could be done whether it be to a model or to create a realistic 'photo' snapshot?

Cheers guys

Aismail,

If you ask a dozen people how to do this, you'll get a dozen answers, and they'll probably all be right, or at least will work. I told someone in another thread I was leaving 2 hours ago, but the people I was waiting on were late. They've arrived, so I'm out of time. Won't be back till late tonight, but this is one of the ways you might get started. What you see represents about 15 minutes or so. I took your wall layout, and extruded it up the height of the straight portion of the walls. Then by moving the ucs, I put a couple of your elevations in lined up with the matching features on the walls. Then by using the lines in your elevations, I used presspull to do the basic shape of the roof. Once you get the basic shapes blocked in, you can go add details like the shape of the eaves from your own elevations. Same with the windows and doors, chimneys, all that stuff. Draw the profile of the chimney, sweep it around a rectangle, and then move it into place. Union the things that need to be one piece and there you are. Dormers can be done the same way. Place a ucs on the wall they line up with, paste in your elevation as a block, draw over the bits you need, erase the block and extrude/sweep/presspull as appropriate. Good luck and let us see how you get on!

To go from your 2D drawing to something that is photo-realistic will take a lot of work. After creating your building as a solid you'll have to add materials and set up your lighting then move on to rendering. Do you have the time to do all this for all or some portion of your building? Is your computer capable of handling the rendering demands?

Maybe you should take a look at Sketchup.

Jack O'neill you absolute legend, that's exactly what I'm looking to do, not sure I follow exactly how you did it but looks wicked. Got the basics from your post so will give it ago tomorrow. Any more info you got to chuck at me, go ahead.

Cheers

Remark is right....modeling it is easy. Rendering it, especially in photorealism...that's hard.

That reminds me of a line for the movie quote thread..."Damage control is easy....reading Klingon, that's hard!"

The command your looking for is rotate3d lay out all your elevations together so the corners are touching you then fold them up 90 degs (note +90 & -90)and it makes the building to look like jacks image above.

Another way is to use the THICKNESS variable for wall thickness and set ucs's on the face of the walls

There's two more ways. See? I said you could ask a dozen people and get a dozen ways...amend that to a dozen or more ways!

I extruded the walls first, then placed the UCS's and pasted in the elevations...six of one, half dozen of the other.

Speaking of elevations...please don't think I'm picking on you, but I found a couple spots you might want to take a look at on both the east and west elevations. First though, take a look at the North elevation. See the columns holding the dormers up? Now look at the east and west elevations. Where do the columns sit?

You'll find that when you get into modeling things in 3D, the devil is in the details. I had thought to model the columns and see if I could figure out a solution for you on what they would look like at the bottom when I noticed another issue you'll want to address. The one on the left is from the east view, the one on the right is from the north view. They aren't quite the same width, which is fine if they are anything other than round, but do you see the main problem with these two views?

This is purley a work in progress drawing, has been handed down to me to make 'nice' if you like. I know what you mean, the east isnt at the same level as the north and the columns are at different levels with different detail.. this has since been sorted but thanks for pointing it out never-the-less. It wont be going to the client like this anyway

Not had a chance to try the 3d out yet tho, too much to do.

Peace

I know what you mean. I actually have carved out a little niche for myself doing just that! A sizeable portion of my business these days is centered around revisions and "fixes" as I call them.

This is what i ment, things that needed revising. All is in order dont worry Any luck with the 3d?

Actually, I haven't had a chance today to work on it. Got in a drawing from one of my customers to do a rush revision on. They had someone offshore do it and made a complete mess of it. I'm not talking little oopses like on your building, they hosed it up big time. That's ok though, like I said earlier...a chunk of my business is fixing other people's stuff. The more screwed up it is, the better I like it. If you get time and wanna see, look in the chat section in a thread about annoying drafting practices.

I will probably play with yours some more tonight. It's an interesting little building. I don't get to work on stuff like that much. The bulk of my work is curtainwall for commercial buildings. The one I was talking about a minute ago is a hospital. Square rooms, square buildings...it's all fun to do, but not as interesting as buildings with character like yours.

While I'm thinking about it, what started me looking at the columns in both views in the first place...are they round or square? Round columns and square columns look the same from the side.

Here's an update on your model. Not knowing the design intent, I'm not quite sure what I'm looking at in a couple places. For instance, the windows/doors under the dormers. In the elevation view, they come all the way up to the bottom of the dormers, penetrating the eave. I cut that out as you can see in the pic, but that can't be right, can it?
