not closed contour, or not all same style! (by Robert)
Hello, I've made some successful sketches and then I can't get the simplest thing to work. I'm following the linkages tutorial.

I make a closed triangle, then with the line segment tool, I click on any Point of the triangle and it shows "not closed contour, or not all same style!" And it shows that even if I close the next drawn thing. Same with rectangles or a combination of both.

When I hover the mouse over the Point of the existing closed triangle it turns yellow so it seems to be selected, so I think the next segment that I'm trying to draw will be connected to that Point, but I continue to see this error. I saw a configuration setting for "Check sketch for closed contour", if I uncheck it, the message goes away, but it doesn't seem like that's a setting that I'd want to be unchecked, right?

I followed a couple of the solvespace challenges and those went ok, then this trips me up.. So confused. Thanks for any help.

Assuming this is going to be one piece, you should make the vertical line of the triangle a "construction" line. Select the line and press "g". I don't know why "toggle construction" is "g" but it does turn the line green ;-)

Your shape is not a proper contour where every line has an "inside" and "outside" That vertical line cuts through the middle of what would otherwise be a proper closed contour.
