Anyone had problems with using bevel?? Iam modeling a well known building and have been using bevel on specific areas to bring out the detail. However im relatively new to maya and I have found that when using bevel it appears to add vertex to my model. For example after beveling if i select a vertex and display poly count is shows that 2 vertex are there layed ontop of each other, the other problem is i have found it sometimes even adds faces to my model which has caused me to go on a deleting spree sometimes deleting 3 extra faces from my model layed ontop of each other. A huge waste of time

Anyone have any thoughts or help with this little problem or maybe even a quick fix?? Will the extra vertex and faces cause problems with my completed model?
Thanks
