ishpalsingh,
This image is a lot clearer.
You are apparently using a pole framing building system with
standardized parts such as axis connector and knee connector.
I am unfamiliar with these connectors as I have never seen
a building made with this particular building system.
I did a search on the Internet using key words like
"HS Unilog Rafter" and "Knee Connector" to try to educate myself
but could not find any reference to this building system.
I would like to try to help you model your building in Archicad
but I really need more information in order to do so.
If you could draw a detail showing the geometry
of this connector, it would help.
Thank you,
Peter Devlin
