Turn a sketch into a controlled parametric part

Create a small plate with a centered hole pattern that must stay centered when the plate width changes. Plan relationships, do the sketch, study with an edit-test, act on the weak reference Treating a fully defined sketch as proof of intent, even though the hole pattern can still be defined from the wrong edge. Plan Write the intent: plate width changes, hole pattern stays centered, hole spacing stays fixed. This makes the expected behavior explicit before the CAD system gives you a false sense of completion. Do Sketch the plate around a centerline, constrain the hole centers to that line,…
