There’ll always be extremes - we’re not concerned with them, are we? We can’t be concerned with extremes, or with people who are extreme, or we would all wear head-to-toe garments that covered any trace of skin, just so there would be no chance of leading those who are extremely sensitive, or weak, or broken, into sin. And that’s obviously ridiculous.
As to the desire to draw a line - that’s a totally understandable desire. It’s far easier to draw a line and say this side is good, that side bad. However, life’s not like that. Was it John Paul II who said “Life is a series of different shades of grey and it’s our job to work towards the whiter shades.”?
So I don’t think we can draw a line and say “Nude modelling is wrong” because then we open up a can of worms. We then have to ask, “Well, is any and every painting of a nude wrong?” “Is
every depiction of the nude human form in painting, film, sculpture, photography, drawing wrong?” “Should we paint little loincloths and figleaves on paintings, and knock the penises off statues?” (As wellintentioned but misguided Christians have done in the past.)
(As far as film goes, here’s a good link about how films depicting nudity (and sex, violence and profanity) can be edifying. It’s a list of 45 films that the Vatican recommends we watch.)

(from the article) “In recognizing the merits of these particular films, the commission did not endorse everything these films contain, or gave them any kind of imprimatur or blanket ecclesiastical approval. Movies, like other works of culture, are seldom if ever perfect. Even with good or important ones, the viewer must be able to think critically and sort out the good from the bad.”
another excellent article, again about film but applying to other artforms, is:
catholic.com/thisrock/2004/0411fea1.asp
(from the article) “No. That would be the same kind of thinking that would result in refusal to enjoy the company of imperfect people, to attend an imperfect church, to or eat imperfect food. That is no way to live.”
The key is to view a piece of art, or an action like nude modelling for an art class, with a critical eye - again, this is harder and takes more effort than just saying, “No, it involves nudity, it’s wrong” but if we take the easy path and make such blanket statements, we will miss out on a lot of good art and what could be good experiences; we’ll miss out on things which, when a bit of work is put in, will edify us and make us better Christians and better people.
Kind of getting into a different topic here - “The value of art” or something rather than the topic of the original post.
