Hello,
I am using WEAP 2023. The shape of the arrow and its direction cannot be changed. It persists when I close the WEAP and reopen it.

Eng. Lamine,

Apologies for the slow response. Hopefully you have resolved this by now, but sending a few tips to try in case not-

In the WEAP schematic, go to Schematic, Set WEAP Node size to change the size of your nodes.

Right click on the schematic and Set Area Boundaries and try setting a smaller area.

If this is a river object, try right clicking on it and saying Disconnect Endpoint and then re-attach it. Unfortunately, there is no way to reverse the direction of a river in the schematic.

If you ended up finding a solution, we would love if you could please share with the WEAP forum so we can all learn.

Hope this helps!

Good day, Eng. Lamine,

I also had this problem previously. It was resolved once I have set the area boundaries to the size of the catchment area that I have delineated on WEAP. The arrows seem to be larger when the size of the set area boundary is larger, so I assume the size of the arrows depend on the size of the set area boundary, and not the delineated catchment itself.

I hope this helps.

Regards,
Elaine
