surface & toolpath

[Andy R]

We have created a NURBS surface using CHOOKS Fplot. We are having some difficulty, when the step size is smaller than 0.020 (probably memory) with a message that tells us "reallocting data buffers please wait... 3:90020" which is the followed by an application error Mill7.exe and the program shuts down. We are using Pentium 333MHz with 128M RAM running Windows NT 4.0 and have 639 MBytes available in the Virtual Memory file. The same error occurs on a Pentium 350 with 128 and Windows 98.

Any one know where the data buffers are and if they can be increased?

Is the size of a toolpath of a NURBS surface affected by the number of points, accuracy of the surface?

From the main screen, "Screen" "configure" go to the "allocations" tab and set your database to 100000 (100 MB) and adjust your other settings to a value above the figure you are getting the error for. Don't forget that there are two screens to set up. One for inch and one for metric. Set both the same to avoid crashes if you need to switch between the two. If you do rendering to surface files, you can set the defaults in render to be different, depending on Inch or Metric configuration.
