profile problems

(OP)
i'm having some problems when i make a profile.
for example, i draw some lines and arcs to make a profile but when i make it, mechanical make some changes on the profile, like changes angles and radius. normaly i don't use constrains and it works and i dont no if i need to use it all the time. the only way to make it work is to make a solid by the old way in autocad with pedit or region and then extrude or revolve it.but the big problem is that the changes are so minor that some times i dont see them, and then there are problems on the manufacturing.can anyone help me?

RE: profile problems

Dear Hefestos;

In MDT5 Try "Assist", "Mechanical Options", "Part" Tab and uncheck "Apply Constraint Rules" then your sketch will not, for example, change a 89.5 degree angle to 90 degrees.

You should use constraints more often though because they make your dimensioning work easier. You can draw any sloppy rectangle for example and constrain all 4 sides to be equal, then by using only 1 dimension on any side you can fully constrain the square. Constraints make your work easier.

Regards Adrian

RE: profile problems

You might wanna uncheck the 'Assume rough sketch' option in the part options dialog too..........as far as I know this will sort you out without having to change the constraints options (??).
 I agree you should really constrain your sketches properly if you reckon it may need to change at some point.
