Answer:
When entering imperfections, the following principles apply:
- The members must have the same member rotation.
- When entering imperfections, the direction refers to the local axes y and z; for example, in the case of asymmetrical cross-sections, it is also possible to refer to the principal axes u and v.
- The position and orientation of the imperfection can be affected by the algebraic sign of the imperfection.
It is helpful to display the local member axis systems. To do this, right-click a member. In the shortcut menu, you can activate the display of the member axis systems.
