English grammar: Is there any difference between “seem to have been designed” and “seem to be designed” in the following two sentences?
1.He made a museum, and the metal pieces on the walls seem to have been designed to resemble fish scales.
2.He made a museum, and the metal pieces on the walls seem to be designed to resemble fish scales.
I am an English learner, and your explanation will be much appreciated.
Thank you.

"seem to have been designed" (past tense) "seem to be designed" (present ) even though designed has an "ed" at the end they are speaking in the present tense of viewing the design. More than likely the two sentences would be used interchangeably however it would not technically be the right way of using the sentences.

Either is acceptable, since the design of something is potentially an ongoing state, as well as being a completed action. Most native speakers, however, would prefer the first version.
