Hello, you need to create a plan image of the model you created by modeling in ideRender or importing 3ds. After defining the 3D object and materials, you need to do the following operations in order. 1-You can create a 2D plan view of your 3D model by using the Create automatic plan command from the Change menu or the toolbar. 2-You can draw by using commands such as line, arc, or edit the automatically created plan in the Created Plan view. 3- By using the definition point command, you can draw the corner points that you will use while placing the object on the plan. 4- By using the border or automatic border command, you can make the scan clear when the library object is placed on a scan. The problem you mentioned is only related to the 1st and 2nd phases. Defining it in other stages will provide convenience in use. After editing your library in this way, save it as KTP2 again and the problem will be fixed. Good work.
