Title slide	Welcome to this spoken tutorial on Drawing a Floor Plan using FreeCAD.
Slide Learning Objectives	In this tutorial, we will learn to, Draw a 1 BHK floor plan in FreeCAD. Position doors, windows, openings and ventilators.
Slide System Requirements	To record this tutorial, I am using Windows 11 and FreeCAD version 0.21.2
Slide Prerequisites https://spoken-tutorial.org/	To follow this tutorial, Learners must be familiar with the FreeCAD interface. For pre-requisite tutorials, please visit this site.
Show the image of the Drawing	We will now draw the Floor plan shown in this image.
Point to the image.	Here is the Line plan of 1 BHK house with proper dimensions. We will reproduce this BHK floor plan in FreeCAD using the given dimensions.
Open the FreeCAD. Click on the Start dropdown. Select the Arch workbench from the drop down.	Let us open FreeCAD. I have selected the Arch workbench.
Select the Create New File.	In the Task menu, select Create New File.
Select the Auto. Point to Auto.	Now click on Auto. Auto icon helps to create accurate shapes by automatically defining the relationship between the drawn lines.
Point to the Combo View. In the Working plane setup click XY-plane (base plane).	In the Combo View, the Working plane setup menu opens. Select Top (XY-plane) in the Working plane setup.
Click Top on the Gizmo.	Select the Top view using the Gizmo.
Shows the tool bar. Select the required constraints.	Observe that new tools and icons are seen on the toolbar. Make sure to select the required constraints in the constraints menu.
Select the Rectangle tool. Uncheck the Filled box.	Select the Rectangle tool. Uncheck the Filled check box if it is checked for you.
Drag the cursor to draw a rectangle. In the Combo view, change the dimensions of length to 8200 mm and width to 5000 mm.	Now let us draw a rectangle with 8200 millimetre length and 5000 millimetre width.
Press the mouse wheel and drag.	Let us zoom out the view to see the rectangle clearly.
Click the line on top. Select Offset tool.	Now we need to show the thickness of the exterior wall. For that we need to make an Offset for the rectangle.
Select the rectangle. Select the Offset tool under the Draft modification tools.	Select the rectangle first. Select the Offset tool under the Draft modification tools.
Check the box for Copy. Drag the mouse cursor outwards.	Check the box for Copy if it is not checked. Drag the mouse cursor outwards.
Type the Offset distance as 200 mm Point to the outer rectangle.	Enter the offset distance as 200 millimetres for showing the wall thickness We can see an outer rectangle has been created.
Right click the mouse button.	You can right click to deselect the tools.
Click the second rectangle in the tasks menu. Click Display mode in the Display options. Select the drop down arrow. Click Wireframe.	Now we have to remove the filling of the outer rectangle. For that under Display Options change the Display Mode from Flat Lines to WireFrame. You can see that filling has been removed in the rectangle.
Click the left vertical line of the inner rectangle. Click on the Downgrade tool. Point to the Edges in the Combo view	Now select the inner rectangle. Click on Downgrade tool in the Draft modification toolbar. We can see that the rectangle is downgraded to four edges.
Select Edge in tasks menu. Click on the Upgrade tool. Select each line and click on Upgrade tool.	Now the Edges have to be upgraded to lines. Select any Edge and click the Upgrade tool in the Draft modification toolbar. Similarly upgrade all the other Edges. Observe that the edges have been upgraded to lines.
Click the left vertical line of the inner rectangle. Click on the Downgrade tool. Point to the Edges in the Combo view	Now select the outer rectangle. Click on the Downgrade tool in the Draft modification toolbar. We can see that the rectangle has been downgraded to four edges.
Select Edge in tasks menu. Click on the Upgrade tool. Select each line and click on the Upgrade tool.	Now the Edges have to be upgraded to lines. Select any Edge and click on the Upgrade tool in the Draft modification toolbar.
Select each line and click on the Upgrade tool.	Similarly upgrade all the other edges. Observe that the edges have been upgraded to lines.
Click the inner rectangle’s left line. Select the Offset tool. Drag the cursor to the right side till the mid part of the rectangle. Click on the screen to draw the offset.	Now we need to draw the interior walls. For that, we have to offset the line at the inner face. Offset distance must be the width of the room. That is equal to 4000 millimetre in this plan.
Click on the newly created line. Select the Offset tool. Drag the cursor to the right side of the rectangle. And click on the screen. Follow the same method to draw an offset for the inner rectangle’s bottom line. Repeat the same process for making the thickness of all the other interior walls.	Now we need to provide the wall thickness for the interior wall. For that, offset the newly created line. Offset distance should be the same as wall thickness. That is equal to 200 millimetre as per the plan.
Select the Offset tool. Drag the cursor to the sides of the rectangle. And click on the screen.	We will show the thickness of all the other interior walls. For that we will offset all the lines.
Select the Split tool. Click on the vertices of the line which divide the last two vertical sections of the rectangle. Click on the bottom part of the 6th line from left side of the rectangle and press delete. Click on the bottom part of the 5th line from left side of the rectangle and press delete. Repeat the same process for the 3rd and 4th line from left side of the rectangle. Continue the same process and split the all 4 horizontal lines in the middle.	Let us use the Split tool to separate the unwanted line segments. Let us delete the unwanted line segments. We will follow the same process for all the wall intersections. First split the lines and then delete the line segments.
Select the Line tool. Draw line joining the inner and outer rectangle present in the middle on the bottom side.	We will use the Line tool to break the wall to create a door opening.
Click on the line and Select the Offset tool. Draw an offset for the line. Drag the cursor on the left side and draw the offset.	Now let’s offset this line to make it equal to the width of the door. The door width is 900 millimetre.
Select the Split tool. Now use split tool for separating line segments at the opening. Repeat the same process for all the door openings.	Split the top horizontal line that is in between the door opening. And also split its offset. Press delete key. Now delete the split line segments. Repeat the same process for all the door openings.
Select the Rectangle tool. Drag the cursor from the outer corner on the top left side to the outer corner on the bottom right side.	Let’s use the Rectangle tool for defining the boundary of the building.
Click on the bottom door line and select Offset tool. Drag the cursor below to define Plinth. Change the display mode from Flat Lines to Wireframe.	We have to offset the rectangle to show the plinth of the building. The display mode of this rectangle has to be changed to Wireframe.
Remove the Rectangle which defines the boundary.	This rectangle drawn to define the boundary has to be removed.
Select the Rectangle tool. Draw a rectangle at the opening of the bottom section. Select the Move tool. Drag the rectangle below the opening.	Now let’s use the Rectangle and Line tools to draw the steps. Use Box Selection to select the steps. To enable Box Selection, press Shift and B keys together.
Use box selection and select the steps. Select the Move tool. Drag the stairs upwards joining the bottom line of the rectangle.	Using the Move tool to drag and position the steps.
Follow the same process and make steps on the opposite side of the rectangle.	Now follow the same method to make the other steps.
Point to the drawing.	The wall plan for the building is now ready.
Click File and Save. Enter a Name and click Save.	Let us Save the file with an appropriate name.
