Hi Randazzo,
Sorry about the slow reply, I had to dig up my old Midas manual and  
read about NOESHOW.

Currently there is nothing in Chimera that (like NOESHOW) reads  
constraints/restraints from files and displays them on structures.  We  
have discussed adding similar capabilities, but it has not been done.

Related things you can do now in Chimera are:

- measure and display distances

- measure angles

- rotate torsions, with automatic update of any distance measurements

- draw lines between any pair of atoms, with control over color and  
optional label of each line.  You would do that by creating a simple  
text file describing the lines and reading it in with Pseudobond Reader.
However, you would still have to calculate the violations yourself and  
assign colors accordingly -- not nearly as automatic and convenient as  
using NOESHOW.
