Step 1: Draw a Window

Use Free Hand, Rectangle to draw a window.

First, draw a rectangle 180x150. Then, choose Erase option. This mode allows for drawing a shape that should be removed from the sketch. Draw a second rectangle inside the previous one. The distance between both rectangles should be 8 units.

In the middle draw a 14 units wide mullion.

Step 2: Draw Sashes

Now we need to draw sashes at the height of 3. We can apply the previous drawing and use Free Hand again or change the offset. Drawing with another offset value will create separate objects with the same height. The only condition is that the difference between offsets has to be bigger than 5.

I entered the offset value 10 and later will move it lower. The distance between drawn sashes and the frame should be 3 units.

Step 3: Move the Sashes Lower

Now we can apply the drawing. As you can see we have two separate objects: frame and sashes. Move the sashes lower so that they were at a height of 3.

Step 4: Copy the Window

The first window is ready so we can model the second one. Select both parts of the window and use Copy to copy them.

Step 5: Copy the Sashes

Hide the frame of the copied window. Now, copy the sashes and place both objects like in the second image.

Step 6: Draw a Guide

The hole in the bottom part of our window should be 91 units long. To get this result we're going to draw a guide and then move the bottom rail to this guide.

You can find Guides (U+G) in Utilities list. Draw a 91 units long line from the central part of the sash.

Step 7: Move the Bottom Rail

Use Cube selection (R+C) to select the bottom rail. Exact selection should be disabled. What is the difference? When the exact selection is turned off, only the faces that are entirely contained in the selection are selected. If it's turned on, the selection generates new edges, so you can use cube selection to cut an object.

Apply the selection and move all selected faces to the guide.

Step 8: Group Both Parts of the Sashes

Now the sashes of your second window consist of two parts. Select them and unite (B+U) into one object.

Step 9: Finish the Second Window

Your sashes are ready so you can lengthen the frame. First, you have to show it as you hid it a few steps ago. To show an object you can click on the eye icon next to the object in the list of objects. As it's your only hidden object, you can also use Show All.

Now, use the cube selection again to select the bottom part of the frame and move it so that the whole frame was 249 units long.

The second window is ready. To delete the guide you have to open the Guides tool again and delete it in tool settings.

Step 10: Model Remaining Widnows

Now you should be able to model the remaining two types of windows. One of them is 80 units wide and 150 units high, the second one is 180 units wide and 60 units high.

Step 11: Prepare the Windows for Printing

My suggestion is to copy each window and unite both parts of each of them. Then, make each union 5 times smaller. When using Scale, select Keep Proportion switcher.

Now we have two ways:
- We can print the windows and walls separately and then insert the windows into the walls - that's what I did.
- We can import the windows to the house project and print walls and windows together. Despite the fact that I chose the first option, let me show you how you can move your objects to another project.

Step 12: Saving Objects to the Cloud

To move the object to another project, save this object to the cloud. Then, open the target project and load the object there.

Step 13: Next Lesson

Your windows are ready to print, so we can model the next objects. Our house needs some furniture!

Let's model the beds.
