Drawing View Missing a Machined Pocket
A base plate drawing shows a top view, a front section, and an isometric. The model has a rectangular pocket 25 mm deep machined into the underside, created as an extrude-cut after the main plate feature. The top view shows the pocket edges as visible lines, which is wrong because the pocket is on the far side. The front section A-A, cut through the pocket center, does not show the pocket at all. The drawing was created from a saved view representation that a previous user edited. The part is 200 x 150 x 30 mm, and the pocket is 80 x 50 mm centered. You must issue the drawing today.
1. Diagnose why the top view shows the pocket as visible and why the section omits it.
Read the worked answer
Two separate issues are likely. First, the top view is probably not a true top projection of the current model state: it may have been created from a view representation or design view in which the pocket was suppressed, or the view was edited with sketch lines or a broken association. If the pocket were present and on the underside, standard projection would show it hidden, not visible. Visible lines on the far side suggest either the view direction is flipped (a bottom view mislabeled as top) or the view is stale and has not updated.
Second, the section omits the pocket because the section line or the section view's participation settings exclude the cut feature, or the section depth does not reach the pocket. Check the section line placement through the pocket center, the section view's cut method (full vs offset), and whether the section is set to include all model features or a limited set. Also confirm the section view was not created before the pocket feature existed and left unupdated. Recompute the drawing and check for a suppressed feature in the active view representation.
2. What is your corrective action sequence to issue a correct drawing today?

Work from the model outward. First, open the part and confirm the pocket feature is unsuppressed and the active view representation includes it. Second, in the drawing, right-click each view and check its view representation and design view; set both to Master or to a representation that includes the pocket, then update. Third, delete any manually sketched lines in the top view and re-project, or recreate the view if association is broken. Fourth, edit the section view: verify the section line passes through the pocket, set the section to full and include all features, and update. Confirm the pocket appears with correct hatching and depth.
Finally, verify the top view shows the pocket as hidden lines (or suppress hidden lines per standard), check the isometric for consistency, and run a drawing audit for out-of-date views. Only then issue. If time is short, a recreated top view and section from a known-good representation is faster and safer than repairing edited views.
