I'm using a TI Nspire CX CAS and am working through programming; currently trying to implement a FEM Frame analysis program.

Is there a manner that I can take a set of data points in the form Pn(x,y,z)…from a spreadsheet application and draw a line from Pn(x,y,z) to Pn+1(x,y,z) from the spreadsheet data?

I'm having difficulty finding a decent programming manual for the TI Nspire; does one exist? There seems to be a real lack of methods to enter data.

Fortunately the handheld spreadsheets work very well for data entry for my frame program data, so far.

Thanks in advance, Dik
