SketchUp Three: Building a House

In my previous two posts (One, Two), we learnt some basic techniques for creating models in SketchUp. Now, I am going to jump directly to using these, and other, techniques to build a detailed Scene.

Don’t worry if you struggle to follow this on the first time through! You can always start over, and slowly build up bit-by-bit!

Design Stage

Firstly, it is a good idea to have a plan in mind! Sure, we could just throw a Scene together, adjusting things as we go along, but I prefer to be building towards a Goal! With this in mind, we need a Plan! Searching Google for “royalty-free house floor plans” led me to http://anyaflow.com, where I downloaded this image:

Floor Plan

You may download it directly from me by clicking to show the full Image, and then Saving to your Downloads folder.

Now we can open SketchUp, and start to build!

Start at the bottom

Base

Base

First, we need a surface to work on. Draw out a Rectangle, and size it to be a little bigger than the House will be. (In my example, we can see that the house will be 44’11” wide and 38’7″ long, so I will  make my Base 50’x40′. Remember that we can get exact dimensions by typing them!). I like to give the base some Thickness, so use the Push/Pull tool to bring it up by 1′.

Outline

Now we can start to build the outer walls.

New Tool: Tape Measure. Draw guide lines 1′ from the Right and Top edges.

Offset Tool

Offset Tool

Using these guides, and the Snap Effect, we can draw some of the outer walls. Draw a Line from the intersection of the Guides, about 40′ across the top, and 30′ down the side. Then Select these two lines (Tip: Select one, hold CTRL and Select the other). You can now use the Offset Tool to drag a 1′ ‘copy’ of the Wall. You should have something looking like this:

The Walls So Far!

The Walls So Far!

Now, using the measurements supplied (or worked-out/guessed-at!), we can fill in the rest of the walls.

I used a combination of Drawing straight lines and Rectangles, using Snap Effects, typing Measurements, and Guide Lines (from the Tape Measure tool) to produce this:

Draft Floorplan

Cleaning Up

Now we can get rid of the Guides, and extraneous lines. The Guides are easy. Edit Menu -> Delete Guides! Trickier is erasing all of the extra lines, without clearing lines we want to keep!

Using the Eraser tool, trim the lines back, and also delete the lines “inside the walls:

Erase these bits!

Erase these bits!

We need to check that all of the Lines are connected. Select the Push/Pull tool, and hover over one of the walls. You should see that the entire wall section, and nothing else, is the familiar Spotty Blue. If this is not the case, draw over some of the lines, to make sure they are correctly aligned. You should have something like this:

Ready to Build Walls!

Now use the Push/Pull to raise the walls to exactly 8′ high.

Here is your basic building!

in Section 3a, we will move on to detailing it to actually look like a house. Doors, Windows and textures! We WILL be seeing our old friend the PushMe/PullYou again, and I will also be introducing the Sketchup Warehouse!
Until next time!

Part Three, Section 2

SketchUp Two. Copying, Scaling and Detailing.

In my previous post (SketchUp – A Beginner’s Guide), I introduced some basic concepts of the 3D modelling software. How to make and move basic objects.

Now we move on to slightly more advanced (don’t worry, not very advanced! We’re taking baby-steps here!) techniques.

Copying

Once you have an object, it is a simple matter to duplicate it. Actually,. it is several simple matters, depending upon your preference.

Select your object. You may notice that only part of the object is selected! We need to cover this first!

Selecting Objects

The Select Tool - Top Right of screen

The Select Tool – Top Right of screen

Using the Select Tool, you can select a single line or face. Or you can drag a box around an area, selecting everything withing this box. WARNING: This may accidentally select hidden sections! To avoid this, we can try several options:

First, extra-clicks. A single click will select a single item, such as a Face or a Line. Double-Clicking will select a Face and surrounding Lines. A Treble-Click will select ALL connected items! This is very useful fro a free-standing object, but care must be taken when you  have interconnected objects!

A way to avoid interconnected objects is, as mentioned before, to make your objects into Components. This will stop them from interacting with other objects, and make them easier to select individually.

A third way is to drag a box around your object, but this has the danger of selecting unseen items, such as the rear faces and lines.

I recommend Components.

Back to Copying

Cut Copy Paste

Cut Copy Paste

Now we have selected an Object, we can use controls that are very familiar to some people, as they are the standard Windows Copy/Paste functions. On the Edit Menu, choose Copy. Simple as that. This stores a copy of the object in the computer’s “buffer”, ready to insert into the scene. To do this insert, back to the Edit Menu, and choose Paste. (For those unfamiliar with the terms “Cut”, “Copy” and “Paste”, they refer back to when work was done on pieces of paper, and literally Cut with scissors or a knife, and then stuck into place with a glue or paste.)

The more eagle-eyed of you will have noticed the Control Keys noted at the side of the Menu Functions. These are keyboard shortcuts that you can press, instead of moving the mouse to the Menu, clicking on the Menu, moving the mouse to the correct option and clicking on that option! E.g. instead of choosing Copy from the menu, you can hold the CTRL key, and press the “C” key.

Now we have a copy in the buffer, either use the Edit Menu -> Paste, or press CTRL-V to Paste the Item into the scene. To begin, it will be “floating”, and you can move it to the required position, before clicking to actually place it.

Scaling

The Scale Tool

The Scale Tool

You may create an object, and then want to make it a different size, or have a copy of an object as a different size. This requires the Scale Tool. Select the object you wish to Scale, and then click the Scale Tool. You will see lots of yellow “handles” appear over the object. These can be use to drag/stretch the object.

Scaling Handles

Scaling Handles

Some handles will only stretch in certain directions, while the corners will stretch all dimensions. Try some, and see how it works!

As with other functions, the Dimensions box in the very lower right of the screen will keep a track of how much you are scaling the object. And, as an added extra, you can type a Dimension to set it exactly! Start pulling a handle, and then type 2 <Enter>, and your object will be Twice the size! type 0.5 and it will be half as big as it started! Useful for when exact ratios are required. And an extra bonus feature, you can scale it to an exact distance! Try stretching and then typing 6″<enter>  or 3m<enter>. You should see the object become the size you indicate!

Detailing

It is quite rare that all you will want in a scene is a plain cube, or even several cubes of different sizes. So we need Details. There are so many different ways we can alter an object that I can only discuss a few in this article.

We shall start with the

Push/Pull Tool

Push/Pull Tool

Push/Pull Tool

A very useful feature, this allows you to move a face, or part of.

To Push/Pull a complete face, simply select the Tool, and hover over the Face you wish to move. You should see the familiar blue spots, showing the selected face. Holding the left mouse button down, you can Push/Pull the face. Notice how the Snap Effect can be used to line up the face with other Objects in the scene.

Push/Pull Examples

Push/Pull Examples

To move just part of a face, you must section it off using the Pencil tool. Draw a line splitting the face, and then proceed as before.

The examples (right) show (l-r) a cube with the whole face pushed back, one with a line splitting the front face in half, and the right pushed back, and one with a design Drawn on, and then Pulled forwards!

NOTE: If you are working on a Component, you must first double-click the component to make sure you are working within it, rather than on the main scene. Also, be aware that alterations made to One component will affect all copies of that component!

This tool can be used to create many effects, including removing a section from an object by Pushing it until it is level with the opposing face (Snap Effect!).

We’ll leave it there for today.

Practice with these tools, and experiment with creating your own Objects.

Let me know how you get on, and the best examples I receive might get featured in my next post!

Happy SketchUping!
