FreeCAD is a free open-source 3D computer-aided design (CAD) modeling program. It is a parametric modeling program meaning that the parts or objects you are modeling are defined using specific parameters. And you can always edit the parameters of your 3D model in FreeCAD by going back to the model history and editing its parameters accordingly.

FreeCAD is designed to fit a wide range of uses including product design, mechanical engineering and architecture. Whether you are a hobbyist, a programmer, an experienced CAD user, a student or a teacher, you will feel right at home with FreeCAD.

BIM stands for Building Information Modeling. The exact definition varies, but we can say simply that is how buildings and other large structures like bridges, tunnels, etc.. are modeled today. BIM models are usually based on 3D models, and also include a series of additional layers of information, such as materials information, relationships to other objects or models, or special instructions for building or maintenance. This extra information permits all kinds of advanced analyses of the model, such as structural resistance, cost and construction time estimations, or calculations of energy consumption.

The Arch Workbench of FreeCAD implements a series of tools and facilities for BIM modeling. Although it has a different purpose, it is made to work in tight integration with the rest of FreeCAD: Anything made with any other workbench of FreeCAD can become an Arch object, or be used as a base for an Arch object.

As in the PartDesign Workbench, the objects produced by the Arch Workbench are meant to be built in the real world. Therefore, they need to be solid. The Arch tools usually take care of that automatically, and also provide utility tools to help you check the validity of objects.

The Arch Workbench also includes all the tools from the Draft Workbench, and uses its grid and snapping system. Before beginning, it is always a good idea to browse through the preferences pages of both Draft and Arch and set the default settings to your preferences.

In this chapter, we will see how to model this small building:

and produce a plan and a section view from it:

Notice in the sheet title block the cone on it's side. The graphic is denoting a first angle projection. If the two images were swapped, a third angle projection is declared. In this print it is less important, however in the previous chair drawing it would have had greater significance. First and Third Angle Projection

We are assuming that the exercises in the previous chapters have been preformed, there will be less discussion on previously covered concepts.

Open FreeCAD, create a new document, and switch to the Arch Workbench.
Open menu Edit -> Preferences -> Draft -> Grid and Snapping and set the grid spacing setting to 1000mm, so we have a one meter-based grid, which will be convenient for the size of our building.
On the snapping toolbar, make sure the grid snap button is enabled, so we can use the grid as much as possible.
Set the Working Plane to XY plane
Draw four lines with the Draft Line tool. You can enter coordinates manually, or simply pick the points on the grid with the mouse (if you enter points in manually, insure the Relative mode is not on):
- From point (0,0) to point (0,3)
- From point (0,3) to point (4,3)
- From point (4,3) to point (4,0)
- From point (4,0) to point (0,0)

Notice that we drew always in the same direction (clockwise). This is not necessary, but will ensure that the walls that we will build next all have the same left and right directions. You might also think we could simply have drawn a rectangle here, which is true. But the four lines will allow us to illustrate better how to add one object into another.

Select the first line, then press the Arch Wall button. Notice that it will give you a wall with width and height, centered on the original line.
Repeat this for the 3 other lines, until you have 4 walls. Currently the walls intersect in the corners and are centered over the original lines.
Select the four walls (highlight all 4 walls in the Model tree), and set their Height property to 3.00m and their Alignment property to left (moving the wall off the center lines.) If you didn't draw the lines in the same order as we did above, some of the walls might have their left and right directions flipped, and might need to be set to right instead. You will obtain four walls, on the inside of the baselines whose corners fully overlap:

Now we need to join these walls together, so they intersect properly. This is not necessary when your walls are drawn in a way that they already connect cleanly, but here we need to, since they are overlapping. In Arch, this is done by electing one of the walls to be the 'host', and adding the others to it, as 'additions'. All arch objects can have any number of additions (objects whose geometry will be added to the host's geometry), and subtractions (objects whose geometry will be subtracted). The additions and subtractions of an object can be managed anytime by double-clicking the object in the tree.

Click on an empty space in the geometry window to loose the Model tree highlights
Select each of the four walls with Ctrl pressed for the second thru end choices, the last one being the wall that you chose to become the host
Press the Arch Add button. The four walls have now been turned into one:

The individual walls are however still accessible, by expanding the wall in the tree view.

Set the Working Plane to auto so we are not restricted to the ground plane.
Select the Axonometric View to have a better view of the building front.
Let's now place a door. In FreeCAD, doors are considered a special case of windows, so this is done using the Window tool.
Start by selecting the front wall in the geometry window. This is not necessary, but a good habit. If an object is selected when starting the window tool, you will force the window to be inserted in that object, even if you snap to another object.
Press the Window button.
In the window creation panel, in the Preset field select the Simple door value from the pull down list, and set its Width to 0.9m and its Height to 2.1m
Make sure the Near snap location is turned on, so we can snap on faces
Place your window roughly on the middle of the front face of the wall:

After clicking, our window is placed on the correct face, but not exactly where we want:

We can now set the precise location by expanding the wall (in the Model tree click on the small arrow next to the Wall) and the window objects (click on the small arrow next to the Window in the Model tree highlighting the line Sketch) and changing the Placement property of the base sketch of our door (click on the small arrow next to the Placement line in the Data tab, click on the small arrow next to the Position line in the Data tab.) Set its position to x = 2m, y = 0, z = 0. Our door is now exactly where we want it:

Repeat the operation to place a window: Select the front wall, press the window tool, select the Open 2-pane preset, and place a 1m x 1m window in the same face as the door. Set the placement of the underlying Sketch001 to position x = 0.6m, y = 0, z = 1.1m, so the upper line of the window is aligned to the top of the door.

Windows are always built on sketches. It is easy to create custom windows by first creating a sketch on a face, then turning it into a window by selecting it, then pressing the window button. Then, the window creation parameters, that is, which wires of the sketch must be extruded and how much, can be defined by double-clicking the window in the tree view.

Let's now create a slab
