Have you considered Truss Joist Rafters? I am not sure of your layout and whether there are large open spaces but you can site build some beefy ridge beams by connecting Versalam pieces. I had my last project with (3) 1.75" x 16" versa lam beams. I wanted to break it into 3 pieces so we could construct it without a larger crew and a crane was not an option.

"3" is the hot key to create a break in the roof plan line.

Break your roof plane and drag it across (1), then break it again and drag it up(2) You can do this in plan view or in 3d

Oops, I thought it but I did not type it.

Reduce the size of your eave fascia. The soffit is set to follow that.

For the bullnose return on drywall, ask you clients to squint when looking at the renderings (Pro Tip).

The solid blocking does not have to be continuous but I would make it around 12-16" ( you may have to translate to Canadian math number measure stuff?) at the center of the post to give the post stability from rotating the rim.

Copy your wall type, rename and change that number

This does create a slightly more complex detail to get the connection of the guardrail post. Make sure to spec solid blocking at the guardrail connection and thru bolt back to the beam with additional blocking per the various deck railing framing guides.

Check your local codes. This is current for California Residential code

R309.1Floor surface.

Garage floor surfaces shall be of approved noncombustible material.

The area of floor used for parking of automobiles or other vehicles shall be sloped to facilitate the movement of liquids to a drain or toward the main vehicle entry doorway.

This might be helpful.  

A.I. much?

 Once  you draw this as a door and adjust, change the schedule designation to a window.

Check in the Eldorado Stone catalogue. The Cannonade is a pretty close pattern and you will need to tweak the texture colors to get what you are after.

It is unfortunate that the Print to Model feature was discontinued. This was an older feature that would give you an exploded view that could be printed with cutting out pieces for a cardboard/chipboard model. This could be useful to make .stl files to print walls and assemble. Given the overhang issues with a printed model, the cleanup on the model makes it a time suck that I am not very interested in. If you are sending it out to a printing service, then maybe it would work as a straight .stl

The full Matterpak will not help you as CA can not read the point cloud in the same way Revit can. The floor plan that then give you can be useful but the accuracy is to about 1-2". If you have critical dimensions, I would take those on site. This is based on my owning a Matterport camera and doing multiple scans of spaces.

I just got a Lenovo Slim Pro 9i laptop. It has a 4060 and this laptop is a lot faster than my current desktop in my signature. The real  time raytracing is almost real time.

Here is an example of a project I am working on. The first image is before some minor tweaks in Photoshop. 

In the Box window dbx I have this window described as 84" wide. I would expect that the dimension would go to the framing layer that I have described as the Main Layer. Is there something I can adjust to correct this other than math?

If you build those out of polylines and then convert them to solids, that is probably the fastest way to achieve what you want. Otherwise, if there is some reason that those objects need to report to a material list as beams, hide those objects on a layer and make the polyline objects in plan view and show that layer in the plan view instead of the beams. 

Reduce that to keyframe 23/36 or 37 and 46. That will probably be better. Without being able to control a curve editor for the camera (real digital film term) I put as few keyframes on a walkthrough as possible. Generally, I don't have more than 2 on each curve I place and only use simple arcs. If you need to show a distinct path, I would do two camera passes and fade them together in a video editor with a focused still cut between them to give the film a reason for the cut.

Good luck in your search. One more thing, Portfolio. 

I really don't think this has changed since I was in school. People can digest very little and have short attention spans. You get 10 images before people tune out. I know with digital portfolios people tend to think that more is more but less is still more. 

What rendering style? What size output (image size). I generally keep my videos to around 1200 px wide since most people will view it pretty small on either a phone or a screen a lot smaller than my work computer. 

I like that you are taking this initiative. Also, tying your goal to one software package is very limiting. If you reach out to local interior design firms ask a few questions:

1. What software packages are you using?

2. Would it be possible for me to come in for an informational interview? I am trying to break into this field and I need practice and advice on how to present myself and yours is the type of firm that I would like to work for in the future... (this is from the book "Knock Em Dead", a must read).

Learn Sketchup! Learn the basics of ACAD. Those are likely the most used softwares. If you end up in a small firm, show them Chief Architect and you will be using that at your new office soon.
