SpaceDesign Area is a calculation which allows you to specify a face in a component for use in area calculations.
Specifying Faces to use for areas
Use Layer Name
Place the face in a special layer:
- If you place a face in the layer _SD_AREA within a component or group, it will use that face (including scaling) to determine the area of the Component or Group
Identify face in existing component
To define and use areas for a component:
- Add a new attribute, and use %a% in its calculation.
(Or %a-m% for square meters, %a-cm% for square centimeters or %a-f% for square feet.)
- After placing your component in a model, right click on it and select Define Area
- Select a face in the component to be used as the area.
- Note: This feature will only work if a single face in the component can be used to calculate the area.
Haw to use Area and cost per unit to create a reort
Area is especially complicated because we have to have a face to calculate the area of. You can define the face to use for area in one of two ways:
Specifying Faces to use for areas
Attribute for Area
Then you have to create an attribute to use for the area. or for area * price per square unit
To create an attribute called, area:
- Create a new attribute (e.g. area)
- Set it as numeric and set the number of decimal places desired.
- Set it's calculation as %a-m% - meaning area in square meter.
Cost per Square Meter
If the cost per square meter is fixed for the entire project, then you can use a constant value. If it is different for different components, then you will need to create an attribute for it, and enter a value for each component.
After creating the attribute, you can right click on each component to set the cost.
Cost of component based on area:
Now create a new attribute - which will be the area times cost-per-m2
Set the calculation to: %cost-per-m2% * %area%
Note the drop down box above the calculation area makes it easy to copy and paste the %attribute% formats:
Click on it to bring up a list of attributes to use in the calculation.
Combining Area and Area-Cost
In this example I used one attribute for area, and a second attribute for area cost.
I could have used just one attribute - area cost - by including the %a-m% in the calculation string:
Use: %cost-per-m2% * %a-m% - instead of - %cost-per-m2% * %area%
Extending the area or area-cost by count:
(Not you cannot use %count% in a calculation. Extensions can only be done using a "Extended" attribute.
Create a new attribute for the extended area-cost (area-cost * quantity)
I included all the variables in the report. (This is a good idea during testing) You could suppress some of them from the report later if they are not needed)
- Calculations - setting attribute values based on size of components, or other attributes.
- Area - report on the area of a face in a component.
- Length - report on the length or curves or edge lines in a component.
- Hyperlink Attributes - attributes containing a WEB URL which will link to that URL from the PDF
- Number Formatting - Database and Currency formatting
- List Attributes - creating a list of attributes and settings.
- Filtering - filtering which attributes to include in report.
- Select Entities by Attribute - search for words, phrases or patterns in attributes.
- Auto Generate Attributes - define and edit attributes in an excel spread sheet.
