Hello all. I was wondering if anyone could explain how to get some of these points in this drawing, and hopefully help in getting a dimension.
For this part, I would create a plane on the left end of the part, followed by cylinders for each straight. Then a plane on the right side. Next, I would construct a pierce point for plane 1 and cylinder 1 which would give me midpoint 1. Then construct an intersection point between cylinder 1 and 2, and that would be midpoint 2. I would continue this for the rest of the tube until i get to the last pierce point giving me midpoint 7. I have learned that i can create a cast point on cylinder 2, and it will give me midpoint 2.2; however, I have not yet been able to figure out a way of getting any of the x.1 midpoints.
That is where my question starts: How can i get these .1 midpoints? I feel like I've tried every combination of picking two cylinders and all the different types of points, and have had no luck in getting them. I have XYZ coordinates for these points, but more importantly, i have length-of-straights dimensions that are taken as a measurement between for example 1 to 2.1. This is a crucial measurement to the fit/form/function of our part, and as of now, i have absolutely no way of checking it.
My second question is this: Almost every part we have has a dimension for mid 1 to mid 7 across the Y-axis (as shown). But they will also dimension in this case, the top of cylinder 1 to the bottom of cylinder 7 (relative to the Y-axis) across the Y-axis. Every time i try to measure Cyl 1 to Cyl 2 across the Y-axis (with plus diameter getting me the closest), I never can seem to quite get a passable measurement.
Any help in either of these matters would be greatly appreciated.
The image is too small to see which points are what. Are the .1 points at the start/end of the cylinders? There's no way you can
measure that, as I see it. It should be possible to
construct them with the following method, though (under certain assumptions).
Create a plane of point 1, 2, 3 (red in the picture)
Level to that plane
Construct a circle, tangent to two lines (1-2 and 2-3), with a fixed diameter = 2 x Bend radius,
Construct points (green) as tangent of line and circle.
