exterior brick with a molding polyline

[peterbrown]

I really like the molding polyline feature to make a brick skirt on an exterior wall.

My problem is that windows that extend down into this skirt are partially covered. I cat seem to edit this in section view. Do I have some other options, or is this technique no appropriate for this application?

Try placing breaks in the molding polyline. Select the area between the breaks>open>select no molding. See if that helps.

Ill try that, but I bet it will leave a top to bottom gap instead of an indentation like I need

That's right...it will.

Right off the bat without trying it, try placing a polyline solid in a side elevation with the profile you want. Go to plan view and stretch it across the wall. Go to a front elevation and see if you can place breaks at the top of the polyline and drag the area down. Maybe that would work. This might work in X1 if that's what you're using.

It is sometimes useful to use more than one polyline. Have the lower one cut the doors with it's height set under your lowest window. Have the second one set to cut at the windows with its bottom height matching the top height of the lower molding.

Sorry, my idea won't work, but you could make it work.

Is this what you're wanting?

Yes, thats the look, did you use 3 different molding polylines?

[peterbrown]

I was hoping to do as Bill suggested, use 3 diff m-poly's, one cut by doors, one by windows, and a cap to be cut by windows as well. Attached is my result.

shouldnt the top two automatically be cut by the windows? Do I need to see them in plan view and make my own breaks at the windows? seems like a hassle.

what am I missing here?

thanks

You can fix this specifying the offset of the molding in the DBX. Some trial and error may be required.

Looks like you may need to change the orrientation of your brick.

Back-clipped cross secton of house.

In back-clipped view, I drew a polyline solid (it may be called primitive) rectangle, starting from the bottom left corner. This polyline solid may not necessarily be in the correct place: It may be too close, or far away, from the wall. Look at it in plan view (it will be about 1" thick, and may blend in to the wall. I would suggest drawing it wide to the right, so you can see it sticking past the house. Reshape it later. You might also want to change it's thickness to 4" in the dialog box.

Then, back in cross section, select the polyline solid and then click on the break tool:

1. Click the tool once (it used to be different, and I haven't quite figured out the new way, exactly, but here goes) and then click on the polyline top, once, somewhere near where the first break is. I clicked to the left side of the door.
2. Then, click and drag the right side (top) of the now broken polyline solid down (a bit) because if you don't, and try to do something else, the break you just installed will go away.
3. Click break tool, again, and click polyline somewhere near new beak location (to the right of the door)
4. Drag (I again moved the remaining right side of polyline top) up, to make the "U" shape that will surround the door.
5. Pull the bottom of this door section down to where you want (if you want some brick below the door, that is)
6. Pull the sides to where they belong, next to the door.

Repeat for each window.

Now you'll have a brick wall that should be cut around the door and windows.

The top, if you want to add it, is drawn similarly:
1. Back-clipped cross section (this time from the right side)
2. Draw polyline solid that will be the angled top.
3. Rotate to put at angle.
4. Reshape the backside if you like, to fit up to the house.
5. In plan view, stretch sideways to cover from corner of house to window.
6. Copy, paste, stretch, shrink as needed.

Got it, Bills solution worked. I made the m-poly's from plan view (make room m-poly) and when placed at the window ht. they cut properly. Then I copied that one for the cap. Put them all at the proper elev and presto

Thanks Bill

Use 3 molding polylines if you want and if you are having a brick ledge for the windows, why don't you apply a brick ledge in the window dbx? See image for window sill
