It's time to start putting our trim work indicators around the doors and windows on the outside. And again, I'm on my A-Wall Masonry layer. I'm just going to zoom into this area by the bedroom window and draw a line from the end of the window to the other end of the window.

And I'm going to offset typically 2 inches on either side of the window and I'm going to erase out my guidelines. Now, what I can do to make my life easier is I can multiple copy a lot of these 2-inch offsets. So I'm going to copy this line from the end of this window and I'm looking for similar right-hand sides of openings.

So I've gotten them all done on that side of the building on the right-hand side. I'm going to copy this line from the left brick. I can see here that it's going to be slightly strange, but I'm going to copy it in for right now and we'll get back to that.

And again, I'm copying to the left-hand sides of openings. Now, the reason I think this is strange is that what I really have going on is I have 2 lines on top of one another. So what I'm going to do is I'm going to erase this line here and I'm going to explode my outer perimeter line.

And then I will extend to the face of the building that entity. And now it's cleanup time, so I'm going to trim and I'm just going to select these entities right there. So you can see now I've trimmed them alongside.

Here for the door, I'm going to draw a line and a line, offset by 2 inches, erase these guys. And again, I'm using the keyboard. I'm going E for erase and O for offset, TR and spacebar for trim.

This is my cutting edge and I trim this out right there. Trim, here's my cutting edge, these guys. I can draw a line from the end of the window, from the end of the window, offset by 2, erase these guys, and then copy this entity from end of the window to the top.

I'm looking down, copy this line from the bottom of the window over to there, TR pick, spacebar for trim, these guys. So I've gotten the back around the side of the house, come down towards the front, a line, a line, offset by 2, erase these guys. And then I'm going to copy this line from the end of the opening, end of the opening to the end of the opening, end of the opening, end of the opening.

Copy this line from the end of the opening to the end of the opening, end of the opening. I'm going to pan down, end of the opening, end of the opening. Trim, clean that up.

Trim, clean that up. Trim, select these line segments to clean those up. I'm going to work here on the family room kitchen area, draw a line from the end, offset by 2, erase, and then copy this line from the bottom to the bottom to the bottom.

Copy this line from the top to the top to the top. Trim, clean up. I have an issue to solve down here.

Draw a line, draw a line, offset by 2, erase, trim, and save. Now hopefully you're again realizing that by using the keyboard shortcuts—by going E for erase, O for offset, CP for copy, TR for trim, and using the space bar and or the enter key—it will really accelerate your production speed compared to just doing things with the mouse alone. Now, I really don't need to have this interior rectangle, the interior polyline, so I'm just going to go on and delete that.

When I look at the back door though, I need to do some cleaning up here, so I'm going to go to trim. I'm going to select these guys, put that there, so that's the edge of the masonry. I'm going to draw a line back in through here, and what I'm going to do is to match properties, because technically this line is on the door layer, not on the masonry layer, so I'm going to go match properties.

Here's the match properties icon way over here on the far right, match properties. Here's the source, here's the destination. I'm going to trim, choose the doors, and because the doors would in fact hide what's going on below.

This again is bulk storage; this is an exterior space, so this is the edge of the pad here. What I'm going to do here is trim crossing, pick that, trim crossing here, pick that, draw line segments, match properties, MA for match properties. Here's the source, here's the destination, and that's another keyboard shortcut that's really a lot of fun, MA for match properties.

It's relatively easy to use. Trim here, draw a line from here to here, match properties. Here's the source, the destination.

Trim crossing here, draw a line segment, and match properties. Now check out what happens if I do this. If I go match properties, if I choose this as my source and this as my destination, not only did it carry the layer information, it also carried line type information, so I can go back to MA for match properties.

Here's my source, there's my destination there. It's solid. I'm going to go to the front door, trim crossing, pick this guy, draw a line from here to here, match properties, door, there's the destination, and I believe that we've now gotten all of our poché outlining done for the building, and we've made the appropriate edges of the slab and that sort of thing, so I'm going to save the file.

The last thing that I need to do from a poché standpoint is to put in my hatch pattern for my brick, so I'm going to go to hatch. I'm going to choose ANSI 31, which is probably the most commonly used hatch pattern in the United States, ANSI 31. I'm going to give it a scale factor of 24, and I just know that this hatch pattern scale factor works based on experience.

Again, this is something that you will become increasingly familiar with over time. You'll start to understand that there is not really a commonality in the definitions of the hatch patterns, and you pretty much have to figure it out on your own. Okay, but I just know that the scale factor of 24 is going to work, and so then I'm hitting enter.

When I'm starting, I had the whole view. I'm going to pick in this region, pick in this region, pick in this region, over in this region. I'm just moving my way around the building, and again, I'm just making sure my hatch regions are visible on the screen.

It's one of these attention to detail, and I've gotten them all, so I'm going to hit ENTER and save the file. The last hatch that we really have to do now is for the fireplace, so I'm going to draw a line from here to here at the front of the fireplace. I'm going to draw a line from the mid going down.

I'm going to offset by 18 inches, and half of 3 foot 4 would be what, 1 foot 7, so offset by 1 foot 7. That doesn't quite sound right. I'm going to say 1 foot 8, and I'm going to confirm my distance, DI for distance, 3 foot 4, so again, half of 3 foot 4 is 1 foot 8, but you already knew that. I'm going to go back and fillet and fillet, erase out this line, save the file.

I'm going to go into hatch. I'm going to choose my pattern. I want it to be a herringbone pattern, so I'm looking through my list, and I see that I have a choice for AR herringbone.

It's remembering my scale factor 24 from the last time. I'm going to pick in this region. Again, see how large it is? You can just see that one angled line, so if I take the scale factor and drop it down to 12 and hit ENTER, and then go in the region, you can see that it's not really changing it a lot at all.

If I take it down to a scale factor of 4 and hit ENTER, you're starting to see more of the pattern. Take it down to a scale factor of 1, you can really start to see even more, so again, what's happening here is with the AR herringbone pattern, in fact, the scale factor of 1 is working fine, and I'm going to close the hatch creation, zoom extents, zoom back 1, save the file, and if I'd like, I can go on and turn on my A pattern layer. I see everything is there.

I'm going to save the file, and guess what? We're almost ready to start importing all of our bath and kitchen fixtures from another model into this. Then we start dimensioning. Then we start putting it on a sheet.

Then we start dealing with multi-scale drawings—terrific! Talk to you in a few minutes.
