FIG 2 PY CONTROL AT THE ANALPRET 
Summary 
A computer assisted PC compatible low cost 
been developed with automatic parallax removal, 
is only in experimental stadium yet, i t seems to 
for teaching and pointlike digitizing purposes so 
plotter has 
Although it 
be suitable 
that it may 
be fitted to the graphical working station. The PC serves as 
si ave. 
The solution for Py parallax removal was discussed and 
experienced practically as well. 
The first measuring results show 0.02 -0.04 mm RMS 
errorsincoordinate measurements which are sufficient for some 
purposes.The plotter gives further possibility for writing 
measuring programs under PC control and gives way for
