This is one of those “I never realized” or more like a “duh” moment that I just experienced and thought I’d share since it’s a quick informational post. I promise my next post will be more insightful to those that will be thinking to themselves “duh”, Jonathan’s an idiot, (which of course is well deserved at this moment). But maybe, just maybe, someone will check their batteries to their optical mouse, before they call their CAD Manager or IT Administrator and harass them about why their Civil 3D is hesitating. Yep, that’s it. For a few weeks now, I’ve been noticing much slower zooms using my mouse wheel along with delays in double clicking to edit something. I just figured since I’m working on some big data sets with aerial images that my computer is slowing down. Well, today my mouse completely died on me. I put a new battery in and Voila! No hesitation in any clicks or mouse movements within Civil 3D.
