it's possible to convert a Parameter to a Vector3?

if yes, how?

You can call ToString() on the Parameter and then just parse that into a Vector3.

 

Copied from QCZM source:

        private Vector3 parseVec3(string vec3)
       {
           vec3 = vec3.Replace(" ", string.Empty);
           if (!vec3.StartsWith("(") && !vec3.EndsWith(")")) throw new IOException("Malformed MapEdit File!");
           vec3 = vec3.Replace("(", string.Empty);
           vec3 = vec3.Replace(")", string.Empty);
           String[] split = vec3.Split(',');
           if (split.Length < 3) throw new IOException("Malformed MapEdit File!");
           return new Vector3(float.Parse(split[0]), float.Parse(split[1]), float.Parse(split[2]));
       }

Parameter p = new Parameter(new Vector3(0f, 0f, 0f));
Vector3 v = p.As();
