Drawing 3D models in SketchUp requires a lot of back and forth between your keyboard and mouse. As you become a more experienced SketchUp modeler, you develop a sense of what commands and tools you use most often and what you do and don’t like about the default keyboard and mouse settings.

SketchUp is designed to behave like your hand — more like a pencil than complicated 3D modeling software. SketchUp gets out of your way so you can draw whatever you can imagine, efficiently. Throughout the design-build process, SketchUp helps you.

Tip: Keyboard shortcuts are one of the most flexible ways you can tailor SketchUp to your unique modeling quirks and desires. If you’ve ever wished you could open a specific feature with a single keystroke, get ready to fall in love with the Shortcuts preferences panel. It’ll be one of the easiest relationships you’ve ever had.

Because SketchUp relies so heavily on mouse and keystroke combinations already, the mouse customizations aren’t quite as flexible as the keyboard shortcuts. However, you can change the scroll wheel zooming and the way the mouse and Line tool interact. The following sections explain all the details.

Creating keyboard shortcuts

In SketchUp, you can assign keyboard shortcuts to the commands you use most often, so that the commands are literally at your fingertips.

For the most part, you can customize the keyboard shortcuts however you like, but here are a few guidelines to help you understand what you can and can’t do as you assign shortcuts:

  • You can’t start with a number because that would conflict with the functionality of SketchUp’s Measurements box, and you can’t use a few other reserved commands.
  • You can add modifier keys, such as the Shift key.
  • You can’t use shortcuts that your operating system has reserved. If a shortcut is unavailable, SketchUp lets you know.
  • You can reassign a keyboard shortcut that already exists in SketchUp. For example, by default, the O key is the shortcut for the Orbit tool, but you can reassign the O key to the Open command if you like.

To create your own keyboard shortcuts, follow these steps:

  1. Select Window > Preferences.
  2. In the SystemSketchUp Preferences dialog box that appears, select Shortcuts in the sidebar on the left.
  3. In the Function list box, select the command to which you want assign a keyboard shortcut. If your selection already has a keyboard shortcut assigned to it, that shortcut appears in the Assigned box.
    Tip: When you type all or part of a command’s name in the Filter text box, the Function list box options are filtered to only those options that include the characters you type. For example, typing mater filters the list down to three commands related to materials, as shown in the following figure.
  4. In the Add Shortcut text box, type the keyboard shortcut that you want to assign to the command and click the + button. The shortcut you type moves to the Assigned box. If the shortcut you chose is already assigned to another command, SketchUp asks whether you want to reassign the shortcut to the command you selected in Step 3.
  5. Repeat Steps 3 and 4 until you’ve created all your desired shortcuts. When you’re done, click OK.
Tip: If a shortcut is getting in your way, you can remove it. Simply select the command with the offending shortcut in the Function list box. Then select its shortcut in the Assigned box and click the minus sign button. The shortcut vanishes from the Assigned box — nay, from your copy of SketchUp.
  1. Select SketchUp > Preferences.
  2. In the SketchUp Preferences dialog box that appears, select Shortcuts in the sidebar on the left.
  3. In the list box, select the command to which you want assign a keyboard shortcut. If your selection already has a keyboard shortcut assigned to it, that shortcut appears in the Key column.
    Tip: When you type all or part of a command’s name in the Filter search box, the Function column is filtered to only those options that include the characters you type. For example, typing mater filters the options to three commands related to materials, as shown in the following figure.
  4. In the text box in the lower-left of the Shortcuts preferences pane, type the keyboard shortcut that you want to assign to the command. Your shortcut then appears in the Key column. If the shortcut you chose is already assigned to another command, SketchUp asks whether you want to reassign the shortcut to the command you selected in Step 3.
    Caution: Do not hit enter as it will erase the value entered!
  5. Repeat Steps 3 and 4 until you’ve created all your desired shortcuts. When you’re done, simply close the SketchUp Preferences dialog box.
Tip: If a shortcut is getting in your way, you can remove it. Simply select the command with the offending shortcut in the Function list box. Then delete its shortcut from the text box in the lower left of the Shortcuts preference pane. The shortcut vanishes from the Key column box — nay, from your copy of SketchUp.

If you ever want to reset all your keyboard shortcuts to the defaults, click the Reset All button on the Shortcuts preference panel. If you want to load your keyboard shortcuts onto another copy of SketchUp, find out how to export and import preferences in Customizing Your Workspace

Inverting the scroll wheel

If you use SketchUp with a scroll wheel mouse — which makes drawing in SketchUp much easier, by the way — by default, you roll the scroll wheel up to zoom in and roll down to zoom out.

On Microsoft Windows, you can flip this behavior by following these steps:

  1. Select Window > Preferences.
  2. In the sidebar on the left, select Compatibility.
  3. In the Mouse Wheel Style area, select the Invert checkbox.
  4. Click OK and take your inverted scroll wheel for a test drive.

On a Mac, this preference feature is new to SketchUp 2017. To flip the scrolling behavior, follow these steps:

  1. Select SketchUp > Preferences.
  2. In the sidebar on the left, select Compatibility.
  3. In the Mouse Wheel Style area, select the Invert checkbox.
  4. Click the red close button, and take your inverted scroll wheel for a test drive.

Remapping mouse buttons

Remapping your mouse buttons refers to customizing the way the buttons work. If you’ve used your operating system preferences to flip the right and left mouse buttons because you’re left-handed, your remapped mouse should work fine in SketchUp.

However, if you’ve used a special utility to assign commands to your mouse buttons, you may experience unpredictable behavior or lose functionality in SketchUp.

Warning: Because SketchUp makes extensive use of the mouse buttons in combination with various modifier keys (Ctrl, Alt, Shift), you can easily lose functionality by remapping the mouse buttons.

Choosing mouse-clicking preferences for the Line tool

If you want to customize how the Line tool cursor responds to your clicks, you find a few options on the Drawing preferences panel. Here’s a quick look how you can customize the Line tool’s behavior:

  • Click-Drag-Release radio button: Select this option if you want the Line tool to draw a line only if you click and hold the mouse button to define the line’s start point, drag to extend the line, and release the mouse to set the line’s end point.
  • Auto Detect radio button: When this option is selected (it’s the default), you can either click-drag-release or click-move-click as necessary.
  • Click-Move-Click radio button: Force the Line tool to draw by clicking to define the line’s start point, moving the mouse to extend the line, and clicking again to establish the line’s end point.
  • Continue Line Drawing check box: When either Auto Detect or Click-Move-Click is selected, you can choose whether to select or deselect this checkbox. (It’s selected by default.) When the checkbox is selected, the Line tool treats an end point as the start of a new line, saving you the extra click required set a new start point. If that behavior isn’t your cup of tea, deselect the checkbox. Then go enjoy a cup of tea, knowing that the Line tool now works the way you always wanted.

Sketchup House

——————————————————————————
To start, we’re going to draw the footprint of our house. If it’s a rectangle, you can just activate the rectangle tool by tapping the “R” key, then typing in the measurements of your house and hitting the enter key.
Now that we have the footprint of our house drawn, we’re going to use the push-pull tool to extrude our house into 3D. To do this, activate the push pull tool by tapping the “P” key, click once on the face of your house, then type in the height you’d like to see and hit the enter key. This will extrude your house at the height you entered.
Now that we have our house shape, we’re going to add slope to our roof. Probably the simplest way is to find the midpoint of your house, then use the line tool to draw a line up 3’. Once you’ve drawn your line up, you can draw lines to the two corners to create a face, then erase your center line so that the face you created is one uniform face. Then, use the push-pull tool to extrude this face to the back side of your house.
Remember that you can use inferencing as you do this to quickly draw this new shape to the back side of your house. You can click anywhere on the back side to do this.
Now what we’re going to do is use the offset tool to draw our eave. Remember, the offset tool will draw a series of lines based on the lines around the perimeter of a face. Activate the offset tool, click on your face, then type in a distance, like 6”, and hit the enter key. Now clean up the new face that was created, then push pull it so that you have a 12” overhang on one side, then extrude it back the other way so you have a 12” overhang on the other side.
Now, let’s add a door and a window. To do this, we’re going to use the rectangle tool to draw our door, then use the offset tool to create some trim. You can start by using the rectangle tool to draw your door – in this case, draw a rectangle that’s 3’ wide x 8’ high. Now, use the offset tool to draw 3” of trim. You can push-pull this trim 3” or so to give your trim some detailing.
Let’s do the same thing with our window – draw a window on the wall to the dimensions you’d like, then use the offset and push-pull tools to create your trim.
The other thing we can do now is create a chimney. To do this, I’m going to start by drawing one line right off our roof along the green axis. Once you’ve done this, you can use the rectangle tool to draw a rectangle the size of our chimney. From here, you can either extrude this rectangle down using the push-pull tool, or you can just manually draw in lines along the blue axis that intersect with your roof to fill in the faces. This is probably a cleaner solution.
Finally, if you want to, you can come in and add materials to your house using the materials section in your tray. This is quite easy – just click on the material you’d like, then click on the face you’d like to color in order to apply the material.
One thing I’m going to do really quick is add a wainscot to our model. To do this, all I’m going to do is use the move tool in copy mode to copy the lines around the base of our model up about 3’0”. Simple double click on the face on the bottom to select the perimeter, deselect the face by “Shift Clicking,” and use the move tool in copy mode to move the perimeter lines up about 3’0”. You can push pull it slightly to give it a little depth, then apply a brick material. You could even model a small cap in here if you wanted to.
