Select the two crossing or nearly crossing members. Then use Process - Segment selection to introduce a node at the intersection point. Be sure to check the box that indicates, "Add intermediate nodes at memebr intersections"
There is a tolerance for this that you can control.
There is a similar option in the automatic meshing under Process - Analysis - Finite Element Model tab.
In cases where you have crossing members that should slip past each other, this option should be turned off.
In Ram Elements the position of all members and shells are derived from the node coordinates. To move a structure, you simply need to move the nodes. Tools are provided to make it easy to add, subtract or even multiply the nodal coordinates by a constant as shown in the video below:
If the model contains 2 or more coincident nodes that are associated with different members or shells you will get an error during analysis, "Nodes "##" and "##" or are equal"
To purge and simplify the nodes:
Note, load areas may need to be redefined after some nodes are removed.
First select the elements to renumber (or everything), then right click in the Members spreadsheet and choose Sort - "Reassign Numbers to Selected Elements". A dialog will pop up with the initial number to use. The program will not duplicate numbers so it is safe to renumber from 1, or pick some other logical number. The same can be done from the Nodes, Shells, Areas or Connections spreadsheets too.
