thank you Dor, but i still cannot figure that out. here is my steps:
- import two files into solidworks using 'curve through xyz points
- convert the two splines into entities
- rotate entities
I didn't "composite curve "till now but it does not rotate, am i any step wrong?
You can rotate, move or scale a spline by first making it proportional. (Right click on the spline and in the Property Manager under Parameters, check the Proportional box.)
You can move the spline by clicking on the spline or a spline point and then dragging it where you want it. You can scale and rotate it by fixing one point. To rotate around the red point, you will need to put in some construction lines and dimension the lines. You will want the lines to have perpendicular and/or parallel relationships, removing any horizontal and vertical relationships to allow for rotation.
There may be easier ways to control the rotation of the spline; it's been years since I worked with a proportional spline and I probably forgot how.
