Use a vertex in skRectangle()

Lee_Hesketh

Hi, how could I use a vertex's coordinates as the "firstCorner" coordinates for an skRectangle() function? Am I right by thinking that it must be a 2d vector and I could get it since I am using evVertexPoint, I could use vertexPoint[0] etc., but that only works if the part is in the correct orientation?
Thanks

Assuming you have the sketch plane, you can use worldToPlane https://cad.onshape.com/FsDoc/library.html#worldToPlane-Plane-Vector
to convert the XYZ coordinates of vertex into the 2D coordinates that skRectangle takes.  Just make sure you're using newSketchOnPlane rather than newSketch to create the sketch (or you'll have a coordinate system you probably don't want).

You can do something like worldToPlane(sketchplane, vertexPoint) + vector(2 * inch, -3 * inch)

@ilya_baran How would I manipulate these coordinates to translate it horizontally or vertically?

Once you're in 2D, you should be able to add to the x coordinate to translate horizontally and to y to translate vertically.  Or did I misunderstand your question?

Well this is what I've written in the code

skRectangle(sketch1, "rectangle1", {

                                        "firstCorner" : vector(width, -height),

                                        "secondCorner" : worldToPlane(sketchplane, vertexPoint)

                                    });
How could I separate the x and y coordinates of the secondCorner to translate the point?

@ilya_baran Thank you so much!
