Second Floor Demolition Plan Tutorial Using CAD Tools for Walls, Doors, and Layer Management

Refine your second floor layout by trimming walls, moving elements to demo layers, and efficiently removing doors using CAD tools.

Explore the process of creating a second floor demolition plan using a modeling tool. The article details the steps involved in fixing errors, selecting specific elements, and moving them to the demolition layer in the model.

Key Insights

  • The modeling process begins by zooming into specific areas, such as a bathroom, identifying errors in the existing floor plan, and rectifying them using the trim and extend commands.
  • Elements such as walls and doors are selected and moved to the 'demo layer', transitioning their status from 'existing' to 'demo'. Multiple elements can be selected at once for efficiency.
  • After all required elements are moved to the 'demo layer', the model is zoomed out to provide an overview of the changes made. The progress is saved frequently to avoid loss of work.

Now let's work on our second floor demolition plan. In our model tab, we will zoom over, or pan over, to the right. And we're going to look at our second floor plan.

On our PDF, we will also move to the right and look at that second floor plan. Let's start by zooming into the bathroom up here. First off, we'll notice a little error in our existing floor plan.

Not a big deal, right? We know how to trim and extend, so we'll do TR for trim, and we'll trim away that little bit of wall, and EX for extend, and we'll extend that bit of wall. So I cleaned that up nicely. Now we're going to select this bit of wall, and this bit of wall, and move them to the demo layer.

So the layer A wall exists, and we'll go up to the A wall demo. Easy peasy. Then we have this door to remove, and we have quite a few doors, so let's try to select them all at once.

We have the one in the bathroom, we have the one in this bedroom, and our two closet doors. One, two. Okay, so that's four doors selected, and we'll swap the layer out from A door existing to A door, you guessed it, demo.

So all those closet doors are going. We're doing pretty good. The bathroom is done, that door is done.

Now we need these closet walls. We'll zoom in a little bit tighter here. We want this first series of wall lines, three lines there.

Then we want to select all of these lines. You can select them individually, like I am here, or draw a window around them. That works as well.

Top left to bottom right is an inclusive window. That's probably the best one to use. We also have this little bit of door jam, and this little bit of door jam, and that's it.

We'll swap the layer from A wall existing to A wall demo. Zoom out, and we will see our work, and it looks really good. Awesome job.
