    Default Create 45 degree cut with the EXTRUDE function

    I was thinking that you can compute the angle if you have the two sides. For example if your board is .5 inches and the cut is .7 inches long you would have a 45.58 degree angle, Has any one tried this

    You may set the grid size as needed (within Extrude), set the Snap-to-grid function. From there, you need only draw your extrude line (for your 45 degree) from one corner to the opposite corner. Then just continue your extrude layout as desired.

    I was trying to find out if anyone had tried this and how the angles turned out.

    Your math may be off! You can use designer to see the results by activating the Snap-to-grid function. From there you can draw your connected lines to scale, assuring your right angle. I used 7 and 5 inches. The attached picture shows the figure in designer. The math shows one angle at 54.5 so the smaller angle must be 35.5.

    Your number is correct, but I used .5 for the height and .7 for the Hipotinoze( Been a long time since geometry class) that would give you the 45.58 degree. We can set the thickness of the board = .5 and the length of the cut .7.

    A right triangle has a base, height & hypotenuse.

    If you're looking for 45 angles, both the base & height need to be the same length (also known as an isosceles triangle).

    If you want a 45 bevel, make the base .5" long and make the height .5" high or adjust accordingly.

    If you need the length of the hypotenuse, you have to trig it out, I think that involves pythagorean theorem (a+b=c, where c is the hypotenuse). So for a .5" triangle it'd be .707.

    You are saying the same thing I said except I use the Height and the Hypotenuse. I used the Hypotenuse because its lenght is show by the program, the height is the wood.
    If you are looking for the angle needed. You would need to compute the angle of each side (180*(n-2))/ n with n being the number of sides. For example for 6 sides the angle would be 120. or (180*(6-2))/6=120.
    Boy this takes me back a couple of years.

    Agreed.
    But we didn't have Google back then either to google (geometric shape) calculator.
    Triangle calculator: http://ostermiller.org/calc/triangle.html
    Regular polygon calculator: http://www.1728.org/polygon.htm

    Wonder how good today's kids are with mental math with instant info like this.

    Only as good as we teach them!

    Take this problem, and first solve it yourself, then give it to others.

    Situation:
    You have a 2 mile track, which a car must travel at an average speed of 60 MPH.

    Problem:
    If the car goes the 1st mile going 30 MPH, how fast must it travel the 2nd mile?
    The answer is not 90 MPH!

    Answer:
    60 MPH gives you 2 minutes to travel the course. You used 2 minutes traveling 30 MPH the 1st mile. You are out of time! You can not make the goal!

    Default Mental math solution

    Before my math problem creates a life of its own, re visit post #9. The answer is hidden in "White" text. Just highlight the post and the solution appears!

    I don't want to hijack the actual purpose of the thread!
