# Konstru ETABS
### ETABS GEOMETRY
 Beams \
Konstru beams are horizontal ETABS frames. Curved beams are not supported.
 Lines
Konstru Lines are ETABS Frames with "None" Section applied.
Braces \
Konstru braces are diagonal ETABS frames. Curved braces are not supported.
 Cables \
Cables are not supported in Konstru for ETABS.
Notes on ETABS Framing Directions \
ETABS automatically flips frames (start and end points) per end point coordinates: The start point is smaller in respective axis but only if the member is parallel to x, y or z axis. the z axis is the governing axis for example when x and y values are negative values. so the lower z value is the start point. similarly if the z value is the same for both ends, the X axis is the governing axis for y values. so the lower x value is the start point.
Columns \
Konstru columns are vertical ETABS frames.\
Vertical Frame (Column) justifications are neglected in Konstru, always set to center/center (insertion point 5).
 Floors\
Konstru floors are horizontal ETABS areas, outline based at the top, openings are added as additional opening areas. Floor justification can only be "top". ETABS Floor geometries cannot be updated from Konstru.
 Openings (hosted)\
Konstru floor openings are working.
 Grids\
ETABS grid-lines can only be uploaded to Konstru but not downloaded.
 Groups\
Konstru groups are ETABS groups.\
Groups have no GUID in ETABS so Konstru uses names as unique ids. If a group is renamed Konstru shows one deleted group and one new group for the next upload instead of a modified group.
 Levels\
Konstru levels are ETABS stories.\
The existing BASE story will not be deleted, but moved to the lowest level on import. We recommend to modify or delete levels manually.
 Load Case (beta)\
Konstru loadcases are ETABS loadcases.\
\- Konstru for ETABS 2015 cannot set Modal cases for ModalEigen and ModalRitz.\
\- Konstru for ETABS 2016 cannot set Modal Case sub type ModalRitz.\
\- Konstru for ETABS doe not support buckling load types. It only supports linear static and nonlinear static load cases.
 Restraints (beta)\
Restraints are automatically created by ETABS at the bottom end points.\
If the all connected members are deleted, restraints are automatically deleted as well. We recommend to change Joints to special Joints.
 Section profiles\
Custom sections in regular shapes (I,C,W,Rectangular etc) are supported. Custom profiles can be created using the Section Designer during download. Irregular shapes are not supported.
Structural Profiles (Wall or Floor layers)\
Structural Profiles are automatically created on download from Konstru.
Walls\
Konstru walls are vertical ETABS areas. Wall justification can only be "middle". ETABS Wall geometries cannot be updated from Konstru. Curved walls are not supported.

# Agent Instructions: Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter:
```
GET https://konstru.gitbook.io/konstru-manual/konstru-revit/konstru-etabs.md?ask=
```
The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
