In the image I have depicted where the yellow pipes should be placed. The first pipe red number 1 starts where the red arrow is pointed and it should be finished where the violet number 1 is placed. The same thing with the second pipe. The pipes should go up to a construction to hold it.
I have added a rectangle which helped me to draw the first pipe.The rectangle is selected on the image. I have moved the first path -27mm according green axis, so now it is placed in the construction.
Now I need to draw the second pipe. When I display the model in the back view I tried to draw it to the plane. I have taken the line tool and wanted to start in the place where you see the circle of the second pipe. The problem is that the line will not start to be drawn on the face of the rectangle been selected on the image. By incident it started on the circle… this is first problem. The second problem comes when I want to click the end of the line to the position where the arc starts on the left. The arc I have already made is not on the face of the rectangle (you remember I have moved the first pipe). So the end point sticks to the path instead to the face… But I need to use the first path to follow the same arc path (in the back view).
Not sure if my message is clear… Simply I want to follow the path but on the rectangle, not on the first path or on the circle in the rear.
Can you describe it how to draw the second path on the rectangle?welding machines 3D - backup.skp (1.8 MB)
