A Gola handle is a recessed channel handle that is set flush with the face of the cabinet, making it possible to open and close slab drawers/doors without modifying the door fronts at all.
I haven't seen a lot of posts about how to do this the way I want in Chief so I figured I would share my method.
The main problem with gola handle integration is that cabinet sides need cutouts so two neighbor cabinets can share the same piece of gola handle without a panel in between. Unfortunately the only workaround for this is to CAD a new cabinet side panel with cutouts, I import these as STL from external CAD, not too familiar with Chief's CAD tools but it's probably pretty easy in there too. I attached the 3DB side and door base side that I use. To adjust drawer heights CAD the assets again or just use stretch planes to relocate the cutouts.
Import STLs as Cabinet Door/Panel and then insert into cabinet under Front/Sides/Back > Left/Right > Custom Face > Side Panel - Inset. If this isn't sitting correctly then adjust in 3D settings for the asset in your user library, and clone the asset and flip 180 for the other side of the cabinet.
You need to change the construction settings to basically 'delete' the cabinet frame - even with "frameless" construction there is still a 'face frame' if you delete the cabinet side.
I set the overlap to 3/8" or 1/2", this is how far the doors/drawers will overlap the gola handle. (this also causes some issues but we'll fix it later).
now we're here:
In Front/Sides/Back > Front add an opening at the top and between each drawer, resize until they are the exact size of the cutouts on the sides and sit exactly over them.
Now we have a cabinet with a 0" face frame but a 3/8" overlay. This means there is no reveal around the edges of the doors so the door panels will extend ALL THE WAY to both sides of the cabinet, so in renders all the drawers in the run will blend together and you can't tell where each cabinet is. You can work around this by recessing the side panels only 9/16" into the cabinet (so they stick out on both sides 1/16"). This makes sizing cabinets a lot harder so I just work around this by using a custom slab door (attached) which is a slab door with a 1/16" x 1/16" stile on both sides, so even though the doors still run into each other it looks like there's a gap. This is pretty invisible (sometimes you need to switch back to slab doors if the weird edges are visible in renders with doors open). If you want to use Gola handles with a door style that isn't slab then CAD your own or just tell your client that slab doors will look better.
This also makes the drawer front stick out past the bottom of the cabinet, you can fix this with a larger horizontal separation on the bottom if it's an issue lining up with fillers etc.
Now I apply the gola handles as molding. Molding attached for the L-channel and C-channel handles. I use L-channel for the top drawer under the counter but you can also use C channel here. This should probably be made in Chief as a molding polyline but I haven't bothered to figure those out yet. So feel free to do that
Now we have realistic looking Gola handles that will run uninterrupted between cabinets in a run (not the best example because there's a big filler here but use your imagination).
I guess this is not the most popular style for cabinet construction outside of Europe but if anyone needs this guide I hope it's helpful.
