Defining Parabolic curve in 2D Sketch using an equation

David Caldwell Sep 10, 2008 11:57 AM

If I have an equation for a parabolic curve and need to create a curve in solidworks sketch, is there a way to inut the equation to allow for it to draw the parabolic curve?

You can, but it will only be a spline approximation. Check out this macro:

Also, it is a new feature in Solidworks 2009.

*Edit: Right, so I forgot. As mentioned below, Solidworks has a parabola function already. It is in Tools>Sketch Entities...

If it is a "parabolic curve", why not just use a parabola? If you have the equation, you can use the equation to determine the location of two or three key points on the parabola and you will have your curve.

I second Roland. If you have the parabolic equation then it should be as simple as constraining the vertex and one additional point in XY.
