Explanation

1. Andrea and Joseph both used pyramids.
These 2 towers have pyramids.
Andrea and Joseph made them.
Read the other clues to see which tower one person made.
Building with two pyramids on two cylinders on a rectangular prism.       Building with three pyramids on top of three cubes.

2. Joseph and Nicole used cylinders.
These 2 towers have cylinders. Joseph and Nicole made these 2 towers.
Building with two cylinder legs, a rectangular prism, two cubes, and then another equally long rectangular prism on top.       Building with two pyramids on two cylinders on a rectangular prism.

Since Joseph used pyramids and cylinders, this must be his:
Building with two pyramids on two cylinders on a rectangular prism.

That means Nicole made this one:
Building with two cylinder legs, a rectangular prism, two cubes, and then another equally long rectangular prism on top.

3. Nicole, Andrea, and Violeta all used 6 blocks.
This is the only tower left made with 6 blocks.
This tower must be Violeta's:
Building with two cube legs, a rectangular prism, two more cubes, and then a shorter rectangular prism.

4. Evan topped his building with cones.
This is the only tower with cones, so it must be Evan's:
Building with two cube legs, a rectangular prism, then two more cubes with cones on top of them.
