Area Condition Properties

Area Condition Properties, General Tab

Thickness

Thickness allows On-Screen Takeoff to calculate Volume as well as area. Handy for concrete slabs, insulation and bedding.

Slope

Used primarily for roof takeoffs. On-Screen Takeoff will take into account the Rise:Run or Run:Rise. If performing takeoff on an orthographic project (using a 'birds eye' view) use x:12 for slope (Rise:Run), if taking off an area using an elevation plan, use 12:x (Run:Rise) for slope. Only area and volume are adjusted for slope. Here is a table of different slopes, degrees and grades.

Color

Sets the color for takeoff performed using the condition.

Pattern

Sets the pattern for takeoff performed using the condition.

Spacing

Enter a measurement to set the spacing to be used in non-solid and non-transparent patterns. This only affects how the takeoff is displayed and has no bearing on measurement quantities.

Results

There are three quantity areas available. See the UOM chart in Section 7 - Databases for more information on measurements.

• The Quantity 1 default is Area (SF), but can be set to SY (square yards) or IN2 (square inches) or even roofing Square (SQ).

• The Quantity 2 and 3 fields allow for measurement of perimeters and volume. Select the appropriate measurement from the drop-down list.

There are two Area results that are special and depend on the Grid as set on the Advanced tab. These results are also dependent on the way the area is aligned to the Grid. See Aligning an Area condition Grid for more information.

Tile Count (Average): Calculates the number of tiles based on area and tile size. For example, for an area of 800 SF with a tile size of 8 SF (ex. 2 X 4 Acoustical Tile) will result in a tile count of 100.

Tile Count (Visible): Calculates the number of tiles based on grid alignment and orientation rather than on area and tile size. While this will add waste to your takeoff, it can be helpful in more accurately projecting labor and material needed if an architect or owner calls for a specific installation of your materials. When you take off the grid, it uses a generic layout. To line up your grid with the plans, you must use the Align Grid feature of the program. If you do not use Align Grid, the count will be based on the initial layout and orientation upon takeoff.

Notes

This field is for whatever notes to include such as how this condition would be build or any other information that helps identify this condition.

Area Quantities

Definition

Area

The surface area of an area condition, less the surface area of any backouts but ignoring the area of any attachments.

Area (Ignore Backout Areas)

The surface area of an area condition, without subtracting Backouts. (For more information on Backouts, see Performing Area Backouts.

Area (Minus Attachments)

The surface area of an area condition, less the surface area of any attachments. You can setup AttachmentsNOT to back out quantities from their parents if you choose. see Attachment conditions for information.

Perimeter

• The linear measurement around the area. (For example, trim or molding around flooring or the forms needed to pour concrete).

• Includes Backout perimeters but does NOT include the perimeter of any attachments.

Perimeter

(Without Backout Perimeters)

The linear measurement around the area, not including the perimeter of any Backouts.

Perimeter

(Plus Attachment Perimeters)

The linear measurement around area including the perimeter of any attachments.

Grid Length (Visible)

• The linear measurement of grid lines with the Grid property selected.

• Does not include any perimeter.

Tile Count (Average)

• The Calculated average count of tiles created.

• (Square foot of area condition) ÷ (Square foot of tile based on Grid).

• Expressed as an each count.

Tile Count (Visible)

The actual count of tiles adjusted for the grid alignment. Counts each partial or complete tile as one whole tile.

Area Counts

The count of times an area condition is used, per page.

Volume

• The amount of mass of an area takeoff, less the volume of any backouts.

• (Surface area (sq ft) x Thickness)

Volume (Ignore Backout Volume)

The amount of mass of an area condition ignoring any Backout volumes.

Volume (Minus Attachments)

The amount of mass of an area condition less the volume of any attachments. You can setup AttachmentsNOT to back out quantities from their parents if you choose.

Area Condition Properties, Advanced Tab

Round Quantity

Select the Round Quantity box to apply this feature.

Round to

Enter a value to the Round to field. Each segment of the condition will be rounded to the nearest increment indicated. For example, if you round to the nearest foot, all takeoff segments for your area, that is-each individual perimeter line- will be rounded to the nearest foot. (if you are drawing a 10' square for example and were rounding to 2', if you are just slightly over on your segments, you could end up with an area quantity of up to 144 sq ft - that's a big difference).

Be careful when rounding, as it can greatly impact on takeoff quantities.

Grid/Tile/Gap

Check the Grid box then, type in the size of your tiles. Next, enter the gap between each tile. This will create a grid pattern at the specified size for your area takeoff object. The gap setting will control the thickness of the lines for the grid area - just like a acoustical ceiling grid.

Display Pattern While Drawing

When taking off large or complex areas, it is sometimes easier to suppress the display of the actual pattern while drawing the area. Once the area is 'closed' - it will fill in with the appropriate fill pattern as set on the General Tab.

Display Dimension

With this box checked, the Quantity 1 result will appear in the center of each area takeoff object that you draw, as in the example below.

If your dimension boxes are too big, you can adjust the Font Size to reduce the size. See Adjusting Annotation Size.

Snap to Linear

Put a check mark in the Snap to Linear box and then choose a position and tolerance for the area takeoff. This feature will make drawing area takeoffs much easier - the area takeoff will 'snap to' nearby linear condition so it doesn't have to be drawn so precisely. It also makes it easier to auto-fill rectangular rooms. Once a room is already outlined with a linear conditions, double-clicking within that space will auto-fill with the selected area condition.

Position

Determines where the perimeter segments of area takeoff will locate themselves in relation to the nearest parallel linear object.

• Inner Edge - places the area object’s perimeter on the inner most edge of the closest parallel linear takeoff object.

• Center - places the area object’s perimeter on the center of the closest parallel linear takeoff object.

• Outer Edge - places the object’s perimeter on the outer most edge of the closest parallel linear object.

Tolerance

Set for the distance that the snap to linear feature uses to snap the area takeoff to the linear takeoff.  For example, if set to 1' 6", then  when area takeoff is drawn within 1' 6" of a linear takeoff object, the area would automatically to the linear takeoff.
