Precision measurement

Sometimes in the normal modelling workflow, elements can become misaligned on a minute scale, while this might seem insignificant to you, Archicad is likely to disagree. Minor inconsistencies like these can prevent Archicad from generating new elements correctly, particularly dimensions.

By default, Archicad’s Measuring Tool will only be accurate to the nearest millimetre for linear dimensions and to 0.01° for angular dimensions, but internally Archicad can calculate dimensions much smaller than this. To make your measurements with the Measuring tool, you can go to the Options ➔ Project Preferences ➔ Working Units… menu. Here you can choose the accuracy for the different measurement types that Archicad can display.

Particularly useful are the Length and Angle Unit decimal places.

Freehand drawing a line or wall doesn’t actually give you the exact length or angle shown on the tracker, rather the length and angle are determined by Archicad based on your mouse position, so this can be off by fractions of a millimetre or of a degree from what the tracker shows.

While it is cliché: appearances can be deceiving.
