Not perfect and I’m not sure I can correct, because I’m not sure exactly what you want and need to say.

Here is my best attempt:

By streamlining the design Tom hopes people will pay attention to simplicity of the materials. He merely employs three short steel wires to connect the solid form and the plastic form, where the wires cross the solid form and the plastic form. The design is intended as a salute to the Arts and Crafts Movement.

Hi!

Thank you so much for your help!

This is two paragraphs.

Munk-Munk’s design principle affords lessons to Tom’s design. Tom tries to create a transition between solid form and rhino plastic, which simply and successfully delivers the sense of transition and contrast between both. He also polishes and designs some streamlines in the solid form, which deepens the transition and contrast between the edge of the solid form and the transition from the top of the plastic form.

Apart from streamline, the design let people to pay attention to honesty of material. Tom merely employs three short steel wires to connect the solid form and the plastic form, which the wires cross the solid form and the plastic form. The design is intended as a salute the Arts and Crafts Movement.

If I put ” by using streamlining, this sentence is not smooth.

What do you mean when you use streamline in the following sentence: He also polishes and designs some streamlines.

Start with the grammar and fix that.

“let”
The design lets
Use correct subject-verb number agreement.

‘streamline’ is an adjective. Don’t use it as the subject of a sentence.
The sentence is definitely not smooth with incorrect usage.
‘streamlining’ is much better than… ‘streamline’ <- what does that mean? It’s not a word.

It’s rather clear that you have difficulty with English idioms. I’m curious as to your native language.

The streamlined design highlights the honesty of the materials.

It would help greatly if you could link to a visual of the item you are trying to describe.

Streamlined usually means cutting something back, like taking out items that are unnecessary, or making it a smoother line, sometimes used to say the item is aerodynamic lines.

The OP seems to be using streamlines as a thing. It doesn’t make sense to me. A streamline can be a noun I believe when used in aerodynamics. Also, it can be used as both an adjective and a verb. In art I don’t think it makes sense as a noun, unless the vocabulary is evolving or I am not familiar with the lingo for that particular subject.

@dabbler What’s not a word?

I believe the OP is using streamline to mean minimalist and to describe tooling to give something a look that we normally associate with Art Deco, @JLeslie. If we had a visual, this would be a snap.

And I believe the assignment may have been turned in already.

@ibstubro

From reading the way it was described I was under the impression that the OP was not referring to the Art Deco style but rather the Arts and Crafts Movement.

I’m neither expert in Architecture nor furniture making but my impression of Art Deco (thinking of the Chrysler Bldng in NY) is that it’s quite a bit more ornate and metallic than Arts and Crafts Movement (thinking of Shaker furniture and bungalows designed with the same simplicity).

Or am I totally off base here?

I lived on South Beach for a while. Art Deco central there. I never heard streamline used in that way and I don’t remember it from History of Art class. But, I’m no expert. I could ask my Aunt or sister; they are much more involved with the art world.

Beat a dead horse.
