Hole on a curved surface problem

[kenppy]

this downloads ok and shows what's in the zip folder but copying gives unexpected error.

There may be other ways of doing it but this looks like what you want; note that all features in the main part were suppressed to keep the zip file <2Mb

This is spot on and thanks .


However I would still like to know how you went about producing this ( step by step please )but because ball-ass.asm is red with errors ( I am guessing because of the suppresand there is no option to un-suppress despite this being in the dir?? ) I cant properly see any clues .


Did you create a plane with a point on it and pattern this ?????


How/where did you get the line /edge for the spiral trajectory ????


Sorry so many questions but as you can tell I need to improve


Thanks again

***you need to open the first part and resume all the features



Did you create a plane with a point on it and pattern this ?????

***the point in the ball was assembled to the first point on the VSS and then patterned by reference




How/where did you get the line /edge for the spiral trajectory ????


***this is a simple VSS surface using one edge of the slot as the origin, the surface was hidden after use.


Sorry so many questions but as you can tell I need to improve


Thanks again

Hey kenppy<?:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" />

Many thanks for your help and most of all your patience and understanding in this .

I have managed to complete the other two rows and have had chance now to break down the stages to see how you achieved the end product . Some I followed , some I will have to sit and play around with , but hey that

You can construct the trajectory as the cross-section of 2
surfaces:
1 - the top surface of the rib(s)
2 - a variable section sweep - surface type - following the
middle of the top surface of one rib.

When you have the trajectory, you can use a variable
section sweep. In the sketch you can relate the position of
the circular cross section to the trajectory.
