Base and Unit Costs

Unit Costs

Base and Unit Costs are fixed costs for the unit or building. They can be set in the data for multi-unit projects. Or they can be set in the Unit Costs array with optional additional fixed costs.

DT Cost and Rooms List

The lists are taken from a data table. The index of the list is used to categorize the list or report.

No Charge Cost Group

Cost categorized with this ID will not be added to the total costs of the estimate.

Cost in Variation Actors

The cost in the Variation Actor can be set in the Choice Buttons, in the Mesh Buttons, or it can be a sum of both.

Data (and prices) can come from the connected data table or be set in the actor itself.

Price Behaviour

Where the price is been taken from and how it is calculated.

Choices Button

The price is set in the Choices Button Details.

Mesh Choices

The price is set in the Object Info array.

Variation Actor Documentation

Cost in Info Actors

Price

Is set in the Object Info array

Cost Group ID

As defined in the data table set in the info map.

A cost group can be defined as No Charge where the cost is shown in the list but isn't added to the total of the unit.

image

Cost in Designer

The Price in the Designer is always bound to the Choice Button. It can be taken from a data table or the designer element itself.

Changing a scenario layout level can change the choices prices with it if the Target Variation Actor is set to stream in and out

Choice Price Override

This allows to override the prices set in the Choice Button array. A chair and table may have the same material choices but the prices are different. This separates the price from the rest of the choice button.
