About the file size of a 3d max file

[Neville]

我想問唔知點解我build 左個3d (use 3d max 2009), 但系個file size 好大, 有冇可能可以reduce 個file size??
我系import autocad file 去個3d max 度build架, 唔知有冇影響呢?
仲有我見到個file 好似有好多好細, 灰色的座標><

URGENT
As i am doing the final year project and i hope every expert can help me, REALLY REALLY thx!!!

你入cad format 做 ref build model, 通常會好heavy,
因為cad generate出來既mesh/polygon會亂哂.
file哂大, 影響save 速度.....
如果想個scale准d...你入cad file後,
我會在max file render 個top view, side view
之後用viewport background 既方法去做ref,
咁就唔會heavy...
