Autodesk Inventor provides a great and extremely simple technique of linking the XLS file with the Inventor files. You can define parameters in the XLS file and then link the XLS file to the ipt file to use the parameters defined in the XLS file. However, you need to be careful while defining the XLS file. You just need to enter the parameter name and its value in the XLS file. The following is one of the examples that you can use in the XLS file. LEN LEN1 WID HT
60 30 20 15
In the first column, enter the name of the parameter and in the second column, enter its value. Note that if you define a parameter as an equation using the other parameters, it may not be displayed in the ipt file when you link it to the XLS file. Hope this helps you in linking XLS file with the Inventor files.
