Error: Arithemetic operation resulted in an overflow at Structure.TStructure.DrawMesh(…)

When trying to edit a model or when creating the mesh, you get the error:

When you close the error, the message returns after a few seconds.

Solution

The message is caused by a point located at distance infinity. To fix it:

• Whenever the error message pops up during the procedure below, click it away and continue with the procedure.
• Make sure the entire structure is visible:
  • Click on . Make sure that for all types, the icon is active.
  • Deactivate the level manager .
  • Click on  to show all hidden elements.
• Open the data table . Show the punt numbers and the point coordinates.
• Look for outliers.
  If you cannot find anything in the X-coordinate, do the same for the Y and Z coordinate.

  For example: a structure measures 10x10m and is situated near the origin. Point 9 with Y-coordinate of infinity, is an outlier.
  If the model is quite big, you can copy-paste the content of the table in EXCEL and use EXCEL-sorting functions to speed up your search.

• When you’ve located the outlier(s), delete them from the model.
  • Go to the menu Select > Point number.
  • Enter the relevant point number and hit ‘OK’. Diamonds will select the point.
  • Hit DEL to remove it from the model.
  • Repeat for all outlier(s).
