The right LCS (local coordinate system) orientation

This article is also available in
ENCZDEESFRITPTNLHUROKRPLTHTRVIZH

All load effects and manufacturing operations are oriented according to the LCS of the member.

The relation between LCS (local coordinate system)ย and linked parts such as plates, bolts, or loads is crucial, manipulating the properties of the member position influences their position.

In the following example turning the member beta direction changes the direction of LCS and causes big differences in the joint. See the position of the stiffener and also check the unbalance forces.

The visibility of the LCS direction can be set in the upper ribbon.

Watch the following webinar, where matching the local coordinate system (LCS) ย of both beams will help you to design the joint.ย
