replace a geometry

Each part is imported in different component. If you import new part, you will found new imported part under new component having the name like <Component_Name>.1. So just delete old part.

For Geometry above method is good & if you you want mesh based update then Part replacement is good based on user profile.See attached sceenshot.

What I meant was that how to put the new part (no mesh) to the location of the old part so that they coincide with each other. When you import a new geometry it will have deferent orientation and position.

Dear edjones,

Each part is modeled with its own co-ordinate system so import all the parts you required and by using translate option organize them as required.

using translate option organize them as required.

Instead think about positioning the CAD part using POSITION option.

There is only one global coordinate system after importing new part in my model. So what should I do in this case? How do you identify positions?

Try to match any three corner points of CAD with FE.

Thank you all!
