Dynamic Units:
All of the default presets utilize a dynamic unit type. This mean the individual units (studios, 1 beds, 2 beds, etc.) stretch to fill the footprint of the building. Additionally a target mix and unit average is used to solve the building layout. You can adjust the mix and size of the units as you need.
Example:
We asked our dynamic 2 bedroom units to be:
- 1200 square feet
- Consume 35% of the units of our building.
This resulted in an exact percentage of 35%, and units ranging from 1,077 square feet to 1,318 square feet with varying options between.
In the lower portion of the properties panel you can control global values of all the units in the building.
Unit depth: Controls the overall depth of all the units in the building.
Inside corners: When toggled off: removes units from being placed on the inside of the building. Is often used when things like mechanical rooms or Back-of-House rooms need to be placed in corners.
Bifurcate corners: Bifurcates all the corner units of a building.
Corner spacing: Controls additional distance on the inside corner units.
Inset depth: controls the inset depth of inside corner balconies.
Dead ends: Disables or enables the use of dead end units at the end of corridors. 
Balconies: Enables/disables the placement of balconies on all units of the building.
Balcony width: Controls the width of all the buildings balconies.
Balcony depth: Controls the depth of all the buildings balconies.
Balcony inset: Controls the inset of all the buildings balconies except inside corners.
Balcony height: Controls the height of all the buildings balconies.
Adjusting the parking ratio:
Select the Units layer and enter the parking ratio you require for each unit size:
Using a Unit Database / Kit of Parts:
If you have exact/specific unit sizes that you need to utilize within your building, you will need to apply a kit of parts and create the unit sizes.
With the Units layer selected, click edit database and then convert to a kit of parts.
You are now in the unit database and will see all of the existing units from the current solve. In the image below we notice the building contained 3 different size studios, 3 different size 1 beds, 3 different size 2 beds, 0 3 beds, an inside corner unit, an outside corner unit, and was solving with dead end units:
If you only want one specific floor plan of each, right click on the extra units and click remove.
Eventually your kit of parts will look similar to this layout:
Should we need an additional bedroom size, such as a 3 bedroom option, click the add unit button from the Inline Units option in the left panel.
You will find yourself in the individual unit editor, make sure to change the name, adjust the category, and increase the bed count for accurate tabulation reporting
You can now adjust the units depth, width, balcony location, additional balconies, bays, and resize/relocate the entry.
This 3 bedroom unit will now always utilize this exact size. It is no longer dynamic. It will no longer stretch to fill the building footprint.
Click back to database and repeat these edits to the remaining unit layouts by clicking on them in the database.
Once you've modified all of the units in the database, you can save it to your assets folder and apply it to future solves. Give the set of units a name and click save to cloud
Click back to site to see your units applied to the building. You'll notice that the dynamic portion of the unit properties are gone and there is no longer a target unit average.
