This is an area in which the truth is essential. Dsi does not want disappointed customers. Let us therefore be clear : CHACAL iX is able to read the library of profile drawings of your operation sheet(s). These drawings are available from your supplier and, with his prior agreement, we can often provide you with them. The editing of these drawings in CHACAL iX (putting in computation points) is a job which, according to the version, we can often do for you. The drawing up of rules specific to you (as from what dimension will you reinforce a given PVC profile or, in aluminium, will you use screwed or inserted angles ?) remains in your own hands, because this is the only guarantee that in the end you will have software suitable to your needs, which you can use in complete freedom independently of your suppliers.
