Virtools is a [[wikipedia:3D Modeling|3D Modeling]] software <ref>Virtools can't create static 3D models; see more at [[mapping]]</ref> by 3DVia, which can be used to create or modify Ballance configuration files and [[Mapping|maps]].Virtools has stopped updating for long, thus the downloading links on the web mostly are Versions before , or Virtools 5. However, since Ballance is made by Virtools 2.1<ref>This version is lost now</ref>, and the file system update at Virtools 4 made it unable for Ballance to load saved NMO files, the Virtools version used to modify Ballance configuration files or map files shall not be above Virtools 3.5.
