What type of body will result when a complete 2D loop is swept with an open profile using the sweep along a guide?

When a complete 2D loop is swept with an open profile along a guide, the result is a solid body. This occurs because the sweeping operation takes the closed shape of the 2D loop and extends it through a 3D path defined by the guide. The closed loop essentially creates a boundary, and as it moves along the guide, it fills the volume within that boundary, forming a solid.

The other options do not accurately describe the result of this operation. An axis body typically refers to a shape that is defined by rotating a profile around an axis, which is not the case here. A created surface would suggest that only a surface is generated without volume, which does not apply since a solid is formed from the loop. An isolated feature would imply a standalone geometric feature that does not form a solid body, which also does not align with the results of sweeping a closed loop.
