Print Full-size Patterns from SketchUp

FSP_#001

Full-size patterns can be printed from a SketchUp model. You can do this with the free version of SketchUp and your own printer.

In my post on making a template for through mortises, I used a full-sized paper pattern that I printed from a SketchUp model. A reader posed the logical and obvious question “can you print a full-size pattern from the free version of SketchUp, or do you need special software and a special printer?” The short answer is yes, and the detailed answer is here.

At left is a screen shot of the SketchUp model. The model is available for free on the 3D warehouse. You can search on the term “Stickley Bookrack” or you can click on this link. Printing from SketchUp isn’t the easiest or most intuitive thing, but once you understand the steps of the process, it isn’t that bad. Generating full-size patterns from a SketchUp model is an incredibly valuable and powerful thing. In this example, the curved shapes of the end, and the size and location of the mortises come from the pattern. These things were drawn once in SketchUp, so there isn’t any need to draw them a second time out in the shop.

Navigate to one of the Standard views and switch from Perspective to Parallel Projection.

There are rules for printing at full size from SketchUp. The first of these is that you have to be in one of the “Standard” views. I have the “Standard Views” toolbar visible, so I just click on the appropriate little house icon. You can also find “Standard Views” under the “Camera” menu, not the “View” menu as you might suspect.That positions the camera in SketchUp to look at the model directly from the right side.

So far, so good. Rule number two is you have to turn off the “Perspective” view of the model and switch to “Parallel Projection”. That change is also made from the “Camera” menu. SketchUp can’t print to a specific scale from perspective. You can print to any scale you want to print working drawings, and you set the scale from the “Print Preview” window.

Under the File menu, select Print Preview

All of this is what things look like on a PC. On a Mac, a similar dialog opens but it isn’t quite the same. The same dialog will open if you select Print, but you need to be careful if you go that route. It’s easy to select OK and find that your printer is cheerfully spitting out dozens of pages.

SketchUp will automatically tile the print to however many pages it needs to get the job done. I’m after a single page showing the top of the side of the bookrack. The print function in the free version of SketchUp (SketchUp Make) is dependent on what is visible on the screen. If you want to print only a portion of a piece, zoom in so it fills most of the screen, and you also may need to resize the model window to roughly the proportions of the paper you want to print on. The actual piece is 10″ wide and to print on a letter size piece of paper, so I need to zoom way, way, in and set the printer to Landscape.

Click on the image for a larger version. Pay close attention to the lower left corner of the dialogue box and the “Tiled” print range.

Here is what the dialogue box looks like. Checking or unchecking some of the boxes changes the options that are available. If you’re in “Print Preview” it’s safe to play around with the different settings to see what happens. When you click “OK” you will see what will go to your printer. To print to full size (or any specific scale) uncheck the box that says “Fit to page”. That lets you change the numbers below Scale. The numbers and units should match, as seen here where an inch in the printout equals an inch in SketchUp.

At the top of the box you can select your printer. I have my machine set to “print” an Adobe PDF file so I can show you the results. I can also select my inkjet printer and put these on letter or legal size paper. If you want a real big print on a single sheet, you can find software online that will let you create PDF files as a virtual printer. Set up the page size for a large sheet, 24 x 36 or 36 x 48 are standard sizes. You can then take (or e-mail) the PDF to someone with a great big printer (I use my local Staples store).

If you print on your own machine, PAY ATTENTION TO THE TILED SHEET PRINT RANGE in the lower left corner or the dialogue box. I took this screen shot before zooming way, way in and SketchUp is ready to print all of the model (along with a great deal of the background) on twenty sheets of paper. That’s 19 sheets more than I want, so I need to play around with the window size and my view to get it down to a single sheet.

Don’t hit “Print” until the preview shows you what you want to see.

Here is the preview that I’m looking for — almost. The blue color is the “sky” background in SketchUp. Because I don’t want to run out of blue ink in my printer, I’ll go to the Styles window in SketchUp and turn off the display of the sky, or select a different style that is just lines. To make this fit, I held a piece of paper up to my screen to resize the window proportions and I zoomed in to fill the screen. I could also have selected legal size paper and wouldn’t need to get so close.

To make everything fit for the bottom of the side, I had to sacrifice the outer edges of the pattern and put it on a legal size sheet in Portrait orientation. Click Patterns From SKP to download a PDF file showing the results, directly from SketchUp. They may not be the prettiest things you’ve ever seen, but the are perfectly usable. When you print from SketchUp, or from a PDF generated from SketchUp make sure that the physical printer is set to print at 100%, not scaled to fit the page or an arbitrary print area. If you need to be sure that the print is at actual size, measure the printed output and compare the number with the SketchUp model dimensions.

  1. Hello,

    We are interested to publish an interview with you which will be published in sketchup-ur-space magazine. We will send questionnaire in the PDF format and you have to give answers for all the questions and return back to us. If you are interested, please send your email id so that we can send the questionnaire to you.

    Thanking you,

  2. These instructions do not give me the results I need. My diagram is small – measuring 4 1/16″ by 2 3/8″ yet Sketchup wants to give me a tiled printout. How do I fix this?

  3. My guess is you should try resizing the window as mentioned above. If there is more than one sheet’s worth of space on screen, SketchUp will tile to additional pages. If you want to e-mail me a copy of your model, I can take a look.

  4. Tired this multiple times using a Mac. It doesn’t even seem to come close so I don’t know how this could be used for printing a pattern. For example, draw a 1″ x 1″ box and it prints out 1.5″ x 1.5″, 18mm x 53mm prints as 26mm x 76mm

What do you think?
