Problems with Triangles…

[oo7_golden_1]

Hello Fusion Community,

I am just now getting into 3D design and I am really enjoying it. Fusion is a very impressive and clean piece of software and I really appreciate that I can learn it for personal use without having to buy it right out of the gate. So, thank you.

I have run into a little hiccup that I can not seem to figure out myself.

I have a component and a body within that component which is in the shape of an equilateral triangle. I am trying to align the center of the face of that equilateral triangle onto the center face of a square (the square is another body within another component).

It seems that other shapes such as squares, rectangles, circles etc. allow me to find true center and align that true center quite easily, but with triangles it doesn’t quite put the center point in the absolute center of the triangle.

It looks like fusion draws a line from the top of the triangle to the bottom center of the triangle and then finds the center of each of the sides of the triangle and draws a line between those 2 sides and then places the center point at that intersection. This works flawlessly for other shapes such as squares but unfortunately doesn’t seem to find the true center of my equilateral triangle.

I need it to draw its centering lines from each of the three corners of the triangle to the opposite sides of the triangle and then place the center point on the intersection of those 3 lines. It seems like its only using 2 lines to try and find the center of the triangle and that centering line between the triangles sides is throwing things off and placing the center point above the triangles true center.

I hope that makes sense (I have included an image to help show what I mean).

Is there an easier way to align triangles to their true center? I have yet to mess with constraints much but maybe this is what people use?

I have also been having problems drawing equilateral triangles which have a specific measurement for its sides from the center point within a sketch.

I am not sure why triangles have been such a problem for me but any help would be greatly appreciated.

You'll need to attach your file to the thread to show the behaviour.  (File/Export/Archive file *.f3d)

Here are triangles drawn with the three options.  All of them have the center in the correct place.  Note: For an equilateral triangle only two lines are needed to find the center.

p.s. You can draw the triangle anywhere in space, then use dimensions and constraints to accurately size and place it.

Thank you for your reply etfrench. I appreciate the help.

Being new to Fusion 360 I certainly need more practice and experience to better learn how to use the tools at my disposal. Learning to better manipulate the dimensions of the triangle after the triangle was drawn was able to help me accomplish my main goal.

I certainly need more practice with constraints as well as I am sure that they would make aligning a triangles center to the center of another object easier as well.

Thanks again for your help.
