Ram Elements - Modeling [FAQ]

Is there a way to add a node or connect two members that are crossing each other?

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.

How can I move all or part of my model?

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:

How can I purge duplicate nodes?

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:

1. Select the problem nodes (or the whole model).
2. Click Process - Purge and reconnect model
3. Then re-select only the nodes and click delete (nodes connected to members are not deleted).

Note, load areas may need to be redefined after some nodes are removed.
