I've added a manufacturer parameter to the appliances menus since the number of part numbers is going to be so large I think it only makes sense to break these drop down boxes up a bit by "type" and "manufacturer". There will also be a "generic" option for those parts/appliances that do not have a manufacturer's logo affixed.



Modeling these various HVAC appliances is a bit tedious since I first have to find somewhat detailed literature or documentation so I can at least get them mostly dimensionally accurate.  Some of the features modeled are my best guesses based on images found online since not everything is dimensioned within the manufacturer's documentation. 

I also try to keep the models fairly low poly but typically there is not more than one or two of these appliances within a given model (for residential projects), so I am not as concerned as I am with HVAC fittings.

The following toolbar will be added for HVAC Appliances:



The HVAC Appliance tool will be for adding AC units, furnaces, fans, VAV's, boilers etc... Essentially any preconfigured HVAC equipment that is not duct work.

The will be simple stand alone assemblies that one can reposition using the native tools.

When you say random can you give more details?

Turn on the Ruby Console in SketchUp and then duplicate the error, copy and paste any error codes and send them to me.

If the plugin encounters and error it will usually abort mid-draw and simply abandon any geometry it has created up until that point at or near the origin of the model.  This is because each wall is initially draw at the origin of the model and then translated and rotated into place as one of the final steps of the draw process.

Turn on your axis in your model, does the geometry appear at or near the origin of the model?

The error could be a simple user error (ie. an incorrect value entered into one of the parameter fields) or it could be a legitimate bug.  The only way to tell is nail down what the error is and then investigate further.

Anyone else have experience with an openings being placed in a random location? Doesn't seem to be limited to doors or windows. They both seem to get installed on other walls. I've tried deleting and reinstalling the walls that are having the issue. Tried uninstalling and reinstalling the most recent version of medeek wall. Tried restarting SketchUp, computer, etc. Nothing.

Oval, round and rectangular are now up and running:

Offsets now seem to be working, now lets turn to rotations, no pun intended:

The next few days will be spent checking and double checking that the transition algorithms are robust and can handle all of the adjustments that get thrown at them. Overall they aren't too complicated, however when you start adding in offsets and rotations things can change very quickly.

This morning I started with offsets and size differences for a RECT-RECT transition, which is by far the simplest of all the transition permutations.  There are three different duct profiles which then yield six different possible combinations at any given transition, and each one needs to be tested and checked:

RECT-RECT
RND-RND
OVAL-OVAL
RECT-RND
RECT-OVAL
RND-OVAL



(The text labels shown are just my temporary debugging markers so that I can track my points)

Adding a rotation to a duct segment is probably going to be the worst case scenario in all of this, but I'm sure I can figure it out eventually.

Transitions and Tees are next:

Version 4.0.3 - 07.03.2025
- Fixed a long standing bug (06/27/2023) with the edit dimension tool for framing dimensions (rectangular walls).

Drawing Fittings:



Editing Fittings:



The library is similar to the Electrical plugins system so one can simply add in as many pre-built custom fitting components as you like.

It would be really nice if I setup my fittings menus similar to the UK outlet and switch menus in the electrical plugin, so that they give you a small preview image. The question is how much work will this be to create.
