Sketch vs. feature order in SOLIDWORKS

EmailFacebookGoogle+LinkedInTwitterShare

Recently, I had a support call with a customer and when he would go to edit a sketch towards the bottom of the feature tree it would suppress other features that seemingly had nothing to do with that sketch. Here is an example of that part.

Sketch 1

Watch what happens when I edit the sketch that belongs to cut-extrude2 which is made up of four through holes.

Sketch 2

Cut Extrude-1 does not exist even though it is higher up in the feature tree. Let's take a closer look at the names of the sketches.

Sketch 3

Sketch 2 is absorbed in to the second cut feature. Sketch 3 is absorbed in to the first cut feature. So even though the features are in the order they were created the sketches are not. Because Sketch 2 was created first editing it will temporarily suppress Sketch 3. To verify the exact order things are created you can switch to a flat tree view by right clicking on the name of your part file and selecting it through the menu.

Sketch 4

Now we can see the true order of all the features even though it is no longer showing what has and has not been absorbed.

Sketch 5

The best plan of attack is to make sure your sketches are in the correct order before creating the features.
