one of the surveyors said: “I began my first employment at

made but it took some time to get them up and running.

What is Topocad?
Topocad is a CAD system developed for surveying
calculations, COGO, transformation and for mapping, design
and GIS connectivity.
A system made for surveyors and designers
Topocad is a true object orientated CAD system especially
made for survey, calculation, mapping and design. Topocad
has been developed by an experienced team of engineers
which resulted that the development of Topocad started from
a surveyor's point of view. Whether you are a civil engineer
or a landscape architect, a surveyor, a tunnel designer or a
database manager, Topocad has the right application for your
The Topocad modules are "add-on" packages that increase the
field of applications. Topocad is a user friendly and easy to
learn CAD tool. You don't have to work with it every day to
be in control. Being on the market for several years, Topocad
has reached many thousands of users in more than 100
countries and is translated into more than 17 languages. The
Topocad maintenance agreement keeps you up to date with
the latest developments.
