PERIMETER CALCULATION TOOL UPDATE

If you think about it, slabs donвЂ™t really have a direction and thusВ they haveВ aВ width or length. This kind of objects only have a thickness. This kind of objects have three dimensions: height, width and length or height, thickness and length.

Objects with a profile and a direction like beams, columns or walls.

Basic dimensionsД«asic dimensions are calculated in the direction of the objects main axes. Each category lists the object classes that the quantity in question is currently calculated for. This document categorizes the quantities based on the technique used for calculating them. Which one is the best for you depends of course on your use case. Geometry based quantities can be calculated with different kind of techniques. For example a wall can either be an instance with single geometry or it can be an assembly with several child objects, which each have their own geometry and thus also their own quantities. Quantities are calculated both for object instances and container objects. In other words Simplebim calculates standardized quantities. Thus quantities are comparable between different models and even between different projects. Simplebim always calculates the quantities with the same logic in a consistent way. Because of this it doesnвЂ™t matter which model author tool was used for creating the models or who made them. Simplebim calculates quantities based on the geometry of objects.

Right-click the field heading for which you want to make a calculation and click Calculate Geometry.You can only perform geometric calculations on attribute tables. Right-click the layer and click Open Attribute Table.You can make calculations without being in an editing session however, in that case, there is no way to undo the results. For more information on z-values and feature geometry types, see Feature class basics.

If the data does not have a vertical coordinate system defined, the units are listed as unknown. The units listed for z and 3D calculations are planar (miles, meters, and so on) as long as a vertical coordinate system has been defined for the layer.

Z-coordinate values and 3D measurements can be calculated regardless of the chosen coordinate system. You can only calculate z-coordinate values or 3D measurements if the feature is z aware.

You can use the Calculate Geometry dialog box to update the area, length, or perimeter of shapefile features, since these properties are not automatically updated when you edit features in shapefiles. If you want to calculate Xmin, Xmax, Ymin, or Ymax, you can do so using Python with the field calculator see Calculate Field examples. It is recommended that an equal-area projection be used when calculating areas. If the coordinate system of the data source and data frame are not the same, you may get a different result if you calculate geometry using the data frame's coordinate system than when you calculate using the data source's coordinate system. Keep in mind that different projections have different spatial properties and distortions. You can only calculate the area, length, or perimeter of features if the coordinate system being used is projected. The tool can calculate coordinate values, lengths, and areas, depending on the geometry of the input layer. The Calculate Geometry tool allows you to access the geometry of the features in a layer.
