2017 Perpendicular Inference

I have a really dumb question relative to the new perpendicular inference in2017. I have a face that is on an angle and I want to draw a circle that is parallel to the face. With the new perpendicular inference, it is really neat and easy to draw a line that is perpendicular to the face but I cannot then use that line to orient a circle (or other object) that is parallel to the original face. Hoping this make sense so someone can enlighten me with an example or tutorial.

The only way I have figured out how to use the new inference so far is to dray a line that is perpendicular to an object. I would hope that it can be used for more than that. :smiley:

Activate the circle tool, move the cursor onto the face until you see the inference “on face”. Then press the down arrow key until you see the face and circle cursor highlight in magenta. Then move the cursor away from the face, click to set a center point, and drag then click to set a radius:

Perfect - exactly what I wanted.

Thanks for the video. :yum:

So did I miss somewhere that the down arrow key give me this new inference?

The ‘get down key*’ parallel/perpendicular* inference was added in SketchUp 2016, so it’s a relatively new one that we didn’t explicitly call out again for SketchUp 2017.

*Not a technical term, but my preferred nomenclature!

Thanks Mark - somehow I missed this along the way. I need to play with it more to learn how to take advantage of it better. I use the other three keys a lot.

OK - for some reason, I am struggling controlling this like I need to. I need to do something like this but I need to make sure the circle I draw is perpendicular to the surface, centered on the rectangle, and a set distance from it as well. I am using 2018 Pro so if there are additional inferences I can use, I would appreciate telling what they are. :blush:

Though you can draw a rectangle from center, once drawn, there is no ‘centerpoint’ inference in the rectangle, so you would have to infer (hoover) on the midpoint of two edges.
One way is to double- click with the Tape-measurement tool active on the surface and then move the guideline to the centre

If you make the box a group you can draw the circle anywhere on that box without them merging and then use move tool.

Thanks to everyone for the feedback. So far, the most successful method I have found is:

  • Go to the face of the rectangle

  • Select the circle tool

  • Use referencing with the circle tool to locate the center of the rectangle & circle

  • Draw the circle on the rectangle face to the desired radius

  • Click on the face of the circle and Push/Pull it the distance I want from the face

  • Select the face of the cylinder that was created with the Push/Pull operation and delete it

  • Go back to the rectangle face and delete the circle which means I now have the desired circle face perpendicular to and centered on the rectangle face.

  • Lastly I can now use the Curviloft tool to make a smooth transition from the rectangle to the circle in the proper context.
