API (Programmatically select a face and create a sketch)

A Face is also an Entity, so you can Select it. Referring to API help:

"In general, an Entity is something that can be selected through the user interface. Entities are useful because they support direct selection through Entity::Select4."

For example:

Dim model As SldWorks.ModelDoc2 'Assuming this is your model Dim face as SldWorks.Face2 'assuming this is your face ... Dim entity As SldWorks.Entity Set entity = face

Dim selectData As SldWorks.SelectData Set selectData = model.SelectionManager.CreateSelectData entity.Select4 False, selectData

model.SketchManager.InsertSketch False

Hope this helps!

Thanks for your help. This example is very USEFUL!!.

Actually, I am writing a bounding box program , in order to measure the part EXTACT size.

Could you also give me some ideas to get the edges of this face entity (just like SolidWorks [convert entities]) ? which API functions can I use?

I want to extract these edges and then use "extrude" for a distance.

Your earliest reply is very appreciated. Alan

Well, can't you just like... convert entities? This is far too easy, record a macro and see.

Interesting - have you tried using the bounding box SolidWorks provides (for example, PartDoc.GetPartBox)?

Yes, I have tried this function. But it just give me a rough size. The returned values are not extactly true. Any ideas on this small project?

I also tried SolidWorks.com provied example, but the performance is very very slow (not acceptable). So, I decided to write by myself.
