<DIV =wordwrap itxtvisited="1">Hi,<BR itxtvisited="1"><BR itxtvisited="1">I am trying to create a coiled tube with 0.014" thick coils, and a pitch value of .1, using the helical sweep tool. However, when I finished defining all the attributes and press OK in the Attributes table, I get an error message saying that some defined dimension are too small compared to other dimensions in the object. So, I changed the thickness value of the cross section from 0.014 to .2, and this time it worked. Is there a way to force Pro-E to accept the 0.014"? This coil thickness is an industy standard value for coiled tubes.<BR itxtvisited="1"><BR itxtvisited="1">Any help will be greatly appreciated.<BR itxtvisited="1"><BR itxtvisited="1">Nanay1 </DIV>
