Unfortunaly, it is not made for 3d printing, and some things end up in mayhem when printing.While the "print unsolid model" checkbox in the pp3dp UP printer dialog will fix many little issues, some sloppy models can not be printed at all. As I am not an expert on sketchup, I would apreceate if other's would contribute to this thread with their observations, advice and links to plugins that make the process from design to printing a bit easier. While meshlab and netfabb have great tools to fix problems, it sometimes is much easier to create a tidy model right away, especially if changing something it would mean that the fixing process would have to be repeated once again. Problems with triangulation from the export pluginThe STL export plugin creates some odd triangled models once in a while.

Whether you are a seasoned writing pro or you barely made it through your senior year English class you can still write great articles that are both entertaining and informative if you just know a few article writing tips.
Even the most well-versed writer understands the importance of brainstorming to help them flesh out their ideas into great articles and now you can too. What is Brainstorming? In a nutshell, brainstorming is the process through which you create the skeleton framework or outline for your articles. Some writers start with a title while others tend to finish the article itself before attempting to name it and the choice you make is entirely individual. Here's how I brainstorm (the condensed version): 1. 2. 3. Now you have a framework from which to craft your article like a pro!

Four points are marked and labeled with their coordinates: (2, 3) in green, (−3, 1) in red, (−1.5, −2.5) in blue, and the origin (0, 0) in purple. Cartesian coordinate system with a circle of radius 2 centered at the origin marked in red. The equation of a circle is (x − a)2 + (y − b)2 = r2 where a and b are the coordinates of the center (a, b) and r is the radius. Cartesian coordinates are the foundation of analytic geometry, and provide enlightening geometric interpretations for many other branches of mathematics, such as linear algebra, complex analysis, differential geometry, multivariate calculus, group theory, and more. A familiar example is the concept of the graph of a function.
