Hello,
The purple and thick black lines on my drawing in the two attachments indicate something's not correct, as none of my other sketches and subsequent extrusions has left them behind. The step that contains them is a cut extrusion to create a curved profile on the underneath of the drawing. If I attempt to delete them subsequent sketches and extrusions show errors.
Can someone suggest what's gone wrong? Presumably, if I can fix the error they won't be showing after I've completed the cut extrusions.
Thank you,
Tim
