Answer:
In "Global Calculation Parameters", there is the setting "Number of divisions of members for result diagrams".
By default, this value is preset to "10".
If members with very different lengths are used in a model, it may happen that the preset value of "10" is too small. This may cause the parabolic moment distribution not to be displayed correctly for the shorter members.
To avoid this problem, enter a higher value; for example, "50".
Thus, a parabolic moment distribution is also displayed on the shorter members.
The length of the sections is based on the length of the longest member in the structure divided by the defined number of member divisions. The finer division of members applies to all members of the model.
