套话，故未做翻译

2.  Units are transferred according to the current program units.

单位制：按照程序当前的单位制导出。

（换言之，生成的PF3D模型的单位制与导出模型时SAP2000的单位制相同。）

注：（如无特别申明，程序指SAP2000）

注：导出前最好将单位制切换成（kN，m，C），否则生成的模型会丢失梁上线荷载。

3.  Only concrete/steel/rebar materials are transferred. If a concrete/steel/rebar material does not exist, a default one is automatically created during the transfer.

For uniaxial/anisotropic materials, the first set of properties are used as an isotropic material (E, Nu, G).

材料：程序仅转换了混凝土、钢材以及钢筋三种材料。即使模型中不存在以上材料，程序也会各生成一个默认材料。（最后一句话是针对单轴材料和各向异性材料的，不会翻译）

SAP2OOO中的分层壳要按下列要求进行设置，并转化为Perform3D中对应的组件。

（下列名词同程序界面显示的内容相同，故未做翻译；）

（->之前的内容对应SAP2000中分层壳的设置，->之后的内容对应生成的Perform组件）

Conc: 1)MatAng=0, S22 nonlinear->Perform fiber wall. (Axial-Moment behavior)

        MatAng=90, S11 nonlinear->Perform fiber wall. (Axial-Moment behavior)

        。。。。。。。

导出模型时，默认的生成了一个Structure Section（截面切割），该截面切割位于支座顶部并通过所有的框架单元和面单元。（感觉后面的话多余，故未做翻译）
