Maybe I'm missing what your trying to do.... but try this....
I don't do Sketchup, so I've been playing with designs in Microsoft Publisher. If you dont have that, try plain old Microsoft Word...
1) create a new document with a page size of LETTER size (8" x 11"?) (I'm translating from English here!)
2) Make sure page is landscape
3) If you want a tear that is say 8' x 4', convert that into inches.... 96" x 48"
4) That will fit nicely on your page at 1/10th scale.... in other words it will be 9.6" x 4.8" on the page
5) Import your chosen image of the profile (Insert/picture command), and if need be drag the corner "handle" to scale it up or down..... hold down SHIFT while doing this to stop it distorting.
6) Now scale it.... to do this insert a RECTANGLE shape over the top of your profile. Double click the rectangle to edit it's properties.... make it's ssize exactly the size of your tear DIVIDED BY 10.... so that's 9.6" x 4.8" in our example
7) Also give the rectangle NO FILL but a line in a nice bright colour. This isnt part of the design, it's just a scaling tool

Now drag the corner handle of your tear profile to line up all round, so it looks like this...

9) Then trawl the web for swooshes & graphicss you like and import them into your design.
10) When you come to scale it all up, its just x 10
Simple
