Runtime error 9 netsys HWS

Hi Claire - I've had a look at the project. Unfortunately, there are some issues with it that are affecting stability. I noted that when I added in FCC's I was also generating a pipe section down to the DXF origin, which suggests to me there are some damaged pipe nodes. Unfortunately, there is no way of identifying these, nor deleting them. 

My best suggestion would be to revert to a backup copy or to start again from scratch.

If starting from scratch, I would recommend the following workflow:

Create each floor by loading the DXF
Once all floors are in place, draw the main part of the lowest floor's network
Use the "Copy services..." from the floors menu to copy the services onto each floor
Use this method to draw in risers and FCC's once the rest of the pipes are in place.

Regards,

The FCC's and System Markers are not copied.

Whenever I set up a multi-floor project, I tend to draw the services for the floor, add a temporary system marker, test the floor in isolation, then copy the services as required. Once all floors are set up, then I consider the FCC's and draw the riser up each floor in turn, finally connecting each floor into the riser.

Regards,
