For horizontal joins in your wall you could use a Complex Profile wall modelling the joins into your profile.
For vertical joins you can place small columns and use a Solid Element Operation to cut them from the wall (and hide the layer the columns are on).
You could do this with beams also for the horizontal joins.
Or you could make up a frame from a curtain wall and use that in a SEO so you can do the horizontal and vertical all in one go. It may also be easier to manipulate the curtain wall scheme if your panel sizes change.
Or you can use a wall accessory to do it.
The advantage of this is it will always match your wall and will allow for door and window openings.
You need to install the accessories add-on (downloads in the HELP menu) and then find an accessory object. I don't think the default Graphisoft accessories will do what you want.
But maybe CadImage have something and there was one made for James Hardie products that may be on there website (although that could just be an Australian thing).
