Hello All,

I'm currently using solidworks 2016 sp5

I have question about the 2D sketch.

So the situation is,

If I had an Assembly with few sub-assembly, and parts.

I made a sketch on main assembly and want to use in all sub-assembly and parts.

Two ways I know are,

Case 1. copy sketch and paste into sub-assembly or part.

Case 2. make new sketch in sub-assembly or part, and use convert entity.

But After I make final model, if change something they may get some inconvenience.

In Case 1, there will be no error, but I have to change all the entities in sub-assembly or part.

In Case 2, if I change something, other than deleting or adding new entities, it works perfect. All the entities follows the main sketch, but as soon as I delete any entity, it causes an error.

So, I'm wondering if there is a way, I can make a linked sketch between main assembly and sub-assembly and parts, so even though if I add or delete entities, it directly applies to sketches that are linked.

Please help me with it.

Thank you
