There are two ways to create a sweep:
On the Structure ribbon in the Entity Modification group, click and choose . The command hint instructs you to pick the profile(s) first, click Done, then pick the path(s) and click Done to finish the sweep.
Pick the profile and paths first. Using this approach, the first item picked is always treated as the profile (thus allowing only one profile) and the subsequent picked items are treated as the path(s). Then on the Structure ribbon in the Entity Modification group, click and choose to finish the sweep.
