Can no longer edit roofs with my mouse

FlamingoKicker​  If you are using mods and CC, try building in save without mods and CC active.  Don't just turn them off in Game Options, move the mod folder out or the Sims 4 folder.  See if that makes a difference. 

Hope this helps.

That is exactly what I did.  Didn't make any difference.  I'm beginning to love the look of flat topped buildings.  Very latin looking.  It is so strange because I have been able in the past to edit building from the beginning so I wonder what could have changed?  I have tried removing the Mods follder and Repairing my game and deleting my cache and restarting and then starting a brand new game and still not able to make edits to buildings (rooms,  roofs,  basements, etc.)

FlamingoKicker​ Ok, so, let's try something a little off the wall.  I have noticed that for some reason, issues with my mice have always shown up first with Sims 4.  Idk why but it seems that it does.  Just a guess but maybe you're seeing the same.  So, try changing your mouse batteries if you use a wireless mouse.  That seems to solve mouse issues for me more often than not.  Btw, I use a Logitech mouse (and keyboard) as well.  At times, I also have to turn the mouse off and back on as it will sort of get lost where it is on the screen.  Weird but I like the feel of the mouse, so I put up with it.  

Hope this helps.

OK,  I will try that because nothing else has had any effect.  The mouse only has the difficulty of clicking on the arrows that allow you to resize building blocks (rooms) as well as roofs and move them bigger or smaller.   But it has no difficulty grabbing windows and doors  and anything else and moving them around.

No,  changing the battery out didn't have any effect at all.  But at least now it has a fully charged battery.

FlamingoKicker​  Ok, then.  Let's try something else unless you already did this.  A new user folder.  That will give you new files in the user folder just in case.  All you need to do is rename your existing "The Sims 4" folder or just move it somewhere else.  Start the game, go through making and placing the sim, save and quit.  Before quitting, you can check to see if anything has changed about the mouse and roofs.  If it has, then you can move your play save from the old folder to the new along with mods and any other folders you want to save like music, overrides, screenshots, etc.  

Hope this helps.

Yes,  I tried that.  I was online with my AI assistant for more than an hour and as weird as this sounds it did work at first.  I was able to get into the raw game after recreatiing it but once I started putting my Saves back in the thing went right back to being uneditable.  The AI never got tired of trying to help but honestly I gave up and went to bed.   I enjoy playing the characters more than building anyway so it isn't a gamebreaker for me.  There are plenty of people who are great builders so plenty of pre-existing buildings I can download and use.  Just frustrating when you can't get stuff to work the way it is supposed to.

One thing that does irritate me about the whole situation is the mechanics of it all.  I mean the mouse can grab and move things in Build mode like doors and windows and plants and anything like that.  But the mouse cursor can not recognize the little arrow "handles" on walls and roofs to move those items.  Why?  What is the difference between those two types of objects in the game in Build mode?
