One problem people often face when making large replica props is making that initial template. Some people draw it by hand on a large sheet of paper, some use a projector, and others print it out on a large sheet from a print shop such as Kinkos. All are valid ways. What I will show you is how to print your template to scale to normal 8.5″ x 11″ sheets of paper that you then tape together. Almost every has access to a printer. I used to use a projector, but have switched over to printing with Sketchup. So onto how to do it!
First, we have our model we would like to print (you could import an image and do the same thing).
Next, switch to the standard top camera view and make sure parallel projection is checked.
Now adjust your sketchup window so that only the part you want to print is visible and takes up the entire viewable area. You may need to adjust the zoom level as well.
Now go to File -> Print. Make sure “Fit to page” is unchecked. Make sure “Use model extents” is unchecked. And finally, change the “In the printout” to 1 inches and change “In Sketchup” to 1 inches.
The “Tiled Sheet Print Range” should show a reasonable number of pages. In the case of this sword 6 pages is correct as the width I am wanting to print is ~44 inches.
Now hit OK and you will now have a tiled print out that you can cut and tape together to make your large to scale template.
