From 2d to 3d

[Neo987]

Hi !

 

I'm a student at a MEP College (here is called Utilites,Equipments Faculty something like that in english) and I always wandered how could somebody create a 2d plan and then turn in into 3d.I've already made a 2d plan of the house I want to design, but I don't know how to fill the walls let's say with tapestry , fill the floor with grindstone, I mean turn it into a realistic 3d view. So if somebody can guide me to some good tutorials about this or tell me what to look for I'll be most grateful.

 

Here is the plan I was talking about and what I made so far:

 

 

P.S. I'm using Acad2010 but used to draw with Acad2008.I heard 2010 is better with 3d, rendering and stuff (whatever that may be).I find 2010 to be much more difficult cuz I don't find the old buttons anymore but I heard is better to learn this interface.So what do you think should I continue old 2008 interface or new one ?

i would have to say.... you should always go to the best and latest...

dont try to master the older version try to master the newer versions....

in this way you'll have the advantage of new tools and other stuff that the old versions dont have....

 

is this your first shot on rendering?

 

here are some things that should be considered in 3d modelling and rendering..

 

1. create 2d plans

2. convert it to 3d

3. add materials

4. illuminate the scene using lights

5. setting the best camera position

6. setting for draft rendering.

7. when satisfied. set for the final rendering boost the settings to high...

8. save the image

 

tell me if there are steps in here you already know and not yet..

so we can see where to start the first step.

Here are some free video tutorials covering 3D in Autocad 2007. Watch these to learn the basics.

tell me if there are steps in here you already know and not yet..

 

I think I have somewhat mastered the 2d, I mean I didn't had any problems in making any 2d plans yet.So after I made the 2d plan I used the command "3do" and started to raise the walls, resistance pillars,doors,windows, all of them drawed with "lines". Now as you can see in the image the walls are transparent, so I guess the next step would be to make the walls solid objects and start puting different materials on the surfaces. This is what I don't know how to do? (by the way is this the way to go or is there a different procedure in making a 3d model of a house ?)

So I think I can say I'm between steps 2 and 3.

 

Thanks for the anwers and tutorials ! Cheers!

Visual Styles will get you started.

[ReMark]

Materials can be applied to individual objects or they can be assigned to a specific layer. Example: all objects that will be assigned a glass material could be placed on layer "Glass". Some people find this to be more efficient. It's up to you.

[arjun_samar]

all of them drawed with "lines".

So I think I can say I'm between steps 2 and 3.

 

i think friend drawed them with lines the wall and etc.. is not the right way of making it 3d....

 

the link that mr. cad64 posted is very excelent help for you... you should check it... thier are many topic on 3d commands be familliarise with it...

3d object having value of xyz lentgh width and hieght.

ok in 3d creation there are 3 types of 3d (i guess:D hehehehe)

 

 

1. 2d wireframe-using lines to draw at xyz axis this can have 3 3d effect look but the truth its not totally a 3d objects.....

2. surface model -a 3d model without mass or hallow inside.

3. solid model- a 3d model with mass ( literally mass ) mostly this is the best 3d type that are using in creation of 3d house... (easy to edit)

 

3d is like 2d if 2d creation first using draw commands then editing it by edit commands like trim etc.

in 3d also it goes that way. first using 3d commands to create 3d object then editing it by solid edit commands.

 

important things in 3d modelling

 

1. 2d commands. (for construction puposes and etc.) almost all commands

2. 3d commands for 3d creation

these are 3d com. that are often use.

a. extrude (solid command) - giving a thikness of a 2d of object or by converting it to 3d solid.

b. slice (edit command) - cutting a 3d object..

c. subtract (edit command) - subtracting 1 3d object by using a another 3d object as an subtraction object.

 

the UCS- user coordinate system... its the icon on the left of the screen this is important the ucs.

 

the 3d view 3d orbit iso views

 

 

here is another link... http://www.dailyautocad.com/autocad/3d-modeling-1-introduction/

[arjun_samar]

check this toolbar... to open new toolbar right click on existing tool bar then a menu will appear select the solid and solid editing...

 

just go to help menu (F1) for more info in the in the commands under the solid and editing tool bar..

[arjun_samar]

friend can you attach the drawing file ( the 2d Floor plan and some elevations?

 

so i can show you how to convert your plan from 2d to 3d.

 

i'll guide you through step 1 to the last step...

 

by the way can you save the file to 2004 version coz at home i only have 2004... only at the office i have 2009..

 

once you have grab you mind to 3d modelling you'll have lots of fun creating this 3d objects.

[Bill Tillman]

Without trying to start a flame war here but I think most can see from my previous posts that this is a bone of contention with me.

 

To the best of my knowledge, you cannot convert a 2D drawing to a 3D drawing. You can make extensive changes to a 2D drawing to make it into a 3D drawing.

 

I saw something today on the tube which showed some women at a home improvement center designing a kitchen in 3D. But this was very specialize and idiot proof software they were using.

 

I'm posting this because in my opinion, far too many users of AutoCAD will speak of the software's power, which it has plenty of. And when I first started using it I thought you just draw a floor plan and then tell AutoCAD to turn the walls into solids and the roof into a a complex shape, etc... But drawing in 3D is not this simple point and click process on a 2D drawing.

 

So to answer this guy's question correctly he should be told that taking a 2D drawing to a 3D drawing is not a process of conversion. Rather it is a process of creating the objects and solids in 3D in the first place.

sorry dont know the right term or phrase or word...

okey no more use of conversion word from now on:D

 

sorry again... for the use of the word converting...

 

ok lets continue and find some usefull things to this guy who is trying hard to create in 3d....

[Neo987]

Morning !

 

So to answer this guy's question correctly he should be told that taking a 2D drawing to a 3D drawing is not a process of conversion.

 

Yes of course I undestand it isn't a magic button which "converts" 2d to 3d.I was just wondering if this is the right way, because it's shure is logical for me to make first a 2d plan and then "raise" it to 3d. This is the only way I could think of. Probably you can make it straight to 3d but I don't have that much space view to do that.

Anyway I'm looking for other methods of doing a 3d house models aswell.

 

So after I looked in my old Acad 3d course I found the command "region" which helped me to do what I was looking for, and that is making the "lines" a solid surface. The problem here is that is very hard to select every little surface and "region" it. So I'm open for suggestions.

Another way to do this is with the command "box" which actualy fills the walls, but again is very hard to "box" every little corner and piece of wall.So maybe if there is some command which makes a "box" by pointing certain points on the ground(floor,X,Y axis)) and then raise it (Z axis) to the complex shape of the walls please tell.

 

Here is the plan so far:

 

[Cad64]

You're making this much too difficult. What you're attempting to do is very simple. Just draw the 2D Floorplan and then Extrude the walls up to the required height. Experiment with the PressPull tool. Draw Boxes for the windows and doors and then Subtract them from the walls.

[mafalda]

Just one more suggestion:

If your 2D floorplan is drawn with simple lines, you will get individual surfaces by extruding them in z-direction. So, if you want it to be a solid, you should first make them joined polylines.

If you prefere to apply "region", it might be easier to use it on the 2D floorplan (on the x-y plan). Then extrude them in z-direction up to required hight, as Cad64 said.

[Neo987]

wow how stupid I was ! How could I not see this earlier "Just extrude the walls up" , of course , so simple yet I didn't see it ! Thanks alot guys !

After that I guess the next step would be to apply materials on the surfaces ! I'll get to you as soon as I finish the walls, windows, doors. About adding materials I know nothing about so this should be new ! Can't wait! See ya!

[Neo987]

by the way, is there a command that deletes the individual lines beneath the newly made polylines ? Just a thought, to make the drawing more cleaner. If not posible how can I select the lines beneath poly and delete them individualy because I had troubles finding every little line

[mafalda]

I don't know any command doing this, that's why I always try to join it all in polylines (it seems cleaner to me too). In your case I would manage 3D objects in an own layer, also the drawing you want to keep, then turn off your new layers and erase the rest.

[Neo987]

Just finished the 3d walls, windows(almost) and doors.Now the next step I think is to put some materials on these surfaces. So how can I put materials that I want from a Jpeg file let's say?

 

Plan step 3:

 

 

P.S. Any ideeas on how to make windows on curved surfaces because I'm really having trouble making "region" and "extrude" windows because it says the are not complanar, and making "box" and "subtract" also doesen't work!

[arjun_samar]

on the non co-plannar,coz it not along on x,y axis. go to acad help menu type ucs to find more info on this..

to apply materials type in the command line rmat a pallet will apear.

are you trying to apply your own jpeg file or image as material? if yes here is a snapshot on how to do it.

 

and autocad have a buit-in materials pallet (a selection of materials) just Ctrl+3 to open the tools pallet.

 

 

here is a link you can download an ebook here register first dont worry its free. just download the ucs topic and materials topic.
