Create a 3D Model of a Building

If y'all have completed the previous lessons in this level, y'all at present take the tools to create a big variety of objects in 3D. This lesson is designed to show how to create simple edifice in 3D from start to finish. The same process tin can be used to build more circuitous buildings as well. First by creating this building and then try drawing your habitation.

This method follows my usual approach of "modeling information technology like you would build information technology". I'll start with a floor plan, then build the walls, make openings for the doors and windows, add doors and windows, then put a roof on it. It just seems similar the most logical approach to me.

Beneath is an epitome of the final building that is drawn in this lesson (with rendering and lighting explained in the next lesson).

Start by setting your units to architectural (DDUNITS). I apologize to everyone in accelerate that uses the metric system, simply most of the viewers and revenue come from the USA, which yet refuses to acquire the metric system. These techniques will work with any floor plan, and then if yous have one with metric measurements, feel free to apply it.

Remember to create new layers for each type of objects yous volition draw (windows, doors, walls, roof, etc).

Now draw the bases of the walls using the dimensions are shown below. Y'all don't demand to dimension it. Optionally, you lot tin can use the (new in AutoCAD 2007) POLYSOLID command.

At present y'all will create regions out of all your wall lines.

Control: REG REGION
Select objects: <SELECT ALL THE LINES> Specify opposite corner: 7 found

Select objects: <ENTER>
3 loops extracted.
3 Regions created.

Y'all should now have 3 regions. If you don't then information technology usually means the your lines don't come across.

Next you are going to EXTRUDE the walls 9' high.

Command: EXT EXTRUDE
Current wire frame density: ISOLINES=4
Select objects: <SELECT THE iii REGIONS> Specify reverse corner: 3 found
Select objects: <ENTER>
Specify height of extrusion or [Path]: nine'
Specify bending of taper for extrusion <0>: <ENTER>

It should appear that nothing has happened. You will demand to get to the SW Isometric view to encounter how the wall were extruded. Practise this and then use the HIDE Command. Something doesn't await right. What you will need to practice is Subtract the 2 smaller regions from the larger region. You should see this result afterward the Decrease and Hide commands.

Now it'southward starting to wait like something. Your walls are well-nigh complete.

Next y'all will add a door or 2. The starting time door, on the outside will exist on the lesser left wall. Start by drawing a rectangle from the center of the outside wall and the other corner @vi,36 - this will create the opening. Your rectangle should look like this:

At present you want to EXTRUDE the rectangle up 6'eight" and Decrease it from the wall.

Create a door layer (or arrive agile if you lot already take ane) and draw a rectangle in the door opening that is 3"ten 3' - put it in the middle of the door opening. Extrude it six'8".

Now create a second door (and opening) on the inside wall parallel to the outside wall that is 32" wide. Afterward you exercise that, the cartoon should expect similar this from the SW Isometric view:

If y'all oasis't saved your drawing yet, at present would be a proficient time.

At present you're going to add together some windows. This will exist done using a similar process as the door. You lot will create openings, then add the window.

Create 2 rectangles in the position shown below.

EXTRUDE the window 36 inches. Them move them up 3'8" in the Z centrality. Remember your relative coordinates from Lesson 1-1?

Command: One thousand
Move
Select objects: ane found
Select objects: 1 found, 2 full
Select objects: Specify base point or displacement: <Option ANYWHERE ON SCREEN>
Specify second point of
deportation or <use beginning point as displacement>: @0,0,3'eight

Now mirror the bottom left box to the reverse wall (Note: It volition be easier if you revert to the elevation view for the mirror command)and the upper box to the inside wall and then y'all have the 4 boxes looking like this :

Next, subtract the four window openings from the walls. After switching to SW Isometric view and using the hide command, your drawing should await similar this:

Now the window panes take to go in. Since this is a simple drawing, you just be putting in a plane of drinking glass to represent the window.

Create a new layer for windows. The easiest way to practise this is just like you created the doors. Make the window one" deep. Once once more, get-go with the rectangle at the base of the window opening, extrude it the top of the window opening and motility it into the eye.

Once y'all take one window made, copy it to the other openings. Save your drawing and and then type in SHADE and choose the K choice. Your building should look similar this:

Wow - now you're getting at that place. Adjacent you will add to the walls to make them the right pitch for the roof.

First you will take to alter your UCS. Start he UCS control and cull the 3Point option by typing 3 <ENTER>. When prompted (watch the command line) select the points shown below:

Afterwards you lot pick the third betoken, the cursor should turn on its side. Now y'all can depict on the side of the building. In this case, you will be drawing a triangular shape to represent the rest of the wall up to the roof.

Describe a LINE from the middle of the peak outside of the wall upwards 6'. Then draw a POLYLINE from 1 corner, to the next, to the pinnacle of the line and use the C option to shut the polyline.

Finally EXTRUDE the triangle -6" so COPY the extruded object to the other side of the building. Erase the vertical line you drew. Y'all should have something like this at present:

To finish the wall, perform a UNION (Lesson 3-11) between the triangular sections and the lesser wall.

You're most washed now. You will need to describe the roof to complete the drawing.

Starting time you volition need to modify your UCS to align it with the slant of the roof. Use the points shown below - and be careful which endpoints you select.

At present draw a RECTANGLE from the elevation left corner of the triangular shape to the bottom of the opposite corner of the other triangular shape. It should like the magenta rectangle below:

New EXTRUDE the rectangle vi". Then re-create 12" down in the Y Centrality and and then re-create information technology 12" up in the Y Axis - when you have the 3 sections UNION them into one object.

Change back to the WCS (UCS <ENTER><ENTER> ) and mirror the roof object to the other side. Check that information technology looks correct past viewing the model from the left and from the front.

The last thing to do is trim the backlog pieces off the elevation of the roof where the two slabs intersect. This will be done using the SLICE command (Lesson 3-11).

Become to the SW Isometric view.

Offset the Piece command and select the roof department towards the back. Then when you are asked to pick three points on the slicing plane, select whatever iii points on the top of the roof section at the front.

Switch to the NW Isometric view and slice other roof department in the same manner. Check to run into that your roof looks correct, and if information technology is, union the two roof objects at present.

Go to the WCS and copy the roof 12" in the Positive X Axis and 12 " in the Negative X Centrality and and then union all iii roof objects. Your building should now look like the one beneath:

Your building is complete. To add a lawn , draw a very large rectangle around the house at the aforementioned Z level as the bottom of the business firm. And so turn information technology into a region and so that materials can be added later.

Relieve the drawing, and then if you like, add materials and return the concluding image. In the image at the top of the lesson, the door is detailed material. More detailed instructions for rendering will be constitute in Lesson three-17.

Here are the materials used for the rendering at the top of the page. You can download them and add them to your Textures folder. The door texture would be used like the stop sign you lot may have rendered in lesson three-fourteen.

Y'all can also endeavour to add more particular to the building if you like. But now you tin can see that using a few commands (in this case virtually 12), y'all can depict decent looking models.

Extra Practice: Build a 3D model of the Cabin Cartoon from Lesson 2-i. How much detail can you add? Door knobs? Window panes?
