how to convert v4 models into v5 in catia.
which can be modified!
V4 model directly open into V5 there is no need to convert it
If you just want to convert one or two V4 models into V5 Catparts, you can just Copy & Paste Special (As Specified). This will give you a file you can modify. There are many videos on the internet that show how to do this. I found this tutorial with the step-by-step instructions: http://www.intrinsys.com/blog/quickly-convert-catia-v4-model-data-to-a-catia-v5-part
(If you have many models to convert, there is a batch utility program you can use.)
i need to modify that model
