I am having difficulties rounding up corners of a rectangle in Sketch Up. I am able to create isolated arcs, but it is not working when trying to make the arc tangent to edges.
In the attached example, I have drawn a rectangle, then I select the 2-point arc tool (A), I chose the starting point on one edge of the rectangle, and then I move the cursor on an adjacent edge and slide the cursor until I find the point for which the arc would be tangent to both edges. However: when I click, the arc disappear and I just see a dashed line. Then it does not allow me to create the tangent arc that was seeing before. I have also tried to double-click to automatically chop off the rectangle, like I have seen online, but it does not work.
Thanks for the reply. I was double-clicking already.
Actually, I just figured it out: it seems I was working with too small objects (a few mm). When trying the same things with 10 times bigger objects it worked.
One thing that I find useful when modeling for 3D printing is to set the Model Units to Meters and model as if millimeters are meters. No need to adjust the scale before exporting the .stl file. Working at the larger size allows for the use of more segments in curves and thus smoother curves. Here’s an example of that sort of thing in this post:
You could benefit yourself by spending some time at The SketchUp Campus. This is a site that will provide the basics for learning the SketchUp modeling process. Also, spend some time at the SketchUp SketchUp YouTube site. It provides much information including how to use each tool.
