Good day Melady
Sounds like you getting the hang of things though.
Like I said: What render style/mode are you using for it to crash? can you do openGL? and post it here.

Due to all the curves you will need to tone it down on the rendering side.
Reflective textures like Chrome on a round surface, like trussing, will not render if values are set too high. Maybe render at a lower DPI or edit texture to be less reflective or make curved surfaces less curved.
Does the program just shut down or is there a "out of Memory" message?
