As you know all too well, many design changes occur late in the process or even many months after the original design was created. Late stage design changes can be a real problem for companies. You want to be able to respond quickly to the challenge, without having to sacrifice your design intent. But, this isn’t always easy to do.
PROBLEM #1 LATE STAGE DESIGN CHANGES CAN BE VERY TIME-CONSUMING
Unanticipated changes create real pressure on project schedules. Often, this can result in teams having to work overtime or even into the weekend to make sure that a project is finished on time, especially if the change is going to radically alter the geometry of the part. If you’re relying on just a parametric design approach, then your models can fail if the constraints and features are not unravelled before redefining the geometry.
