Hi,
Please make the dimension operation more flexible:
in a sketch please make newly added dimension to an element which was already defined by a dimension not become driven but rather the old one to become a driven dimension. It is more logical the old dimension to become driven because the user wants the new dimension, otherwise the user would not waste the time.
AND! please solve that behaviour with disappearing dimensions on trimmed entities!!! It would be nice to see this and other accepted ideas from other users to be included in the next service pack not to wait the inventor 2016.
Thanks
