Using Remove Surfs, you can block, or suppress, imported surfaces from the model even if other parametric features reference them. It creates a new remove surface feature in the model that blocks the required surfaces until you choose to restore them by deleting or redefining the feature.

Each remove surface feature that you have created is assigned a feature ID and number that are visible in the Information Window. Because you can selectively control the removed surfaces within the same removed surface feature, a Legacy object should have as few removed surface features as possible.
