Cleaning up wall corners.

caddict

Not sure what you mean by "routine"...an automatic process?

Anyway, what I tend to do in the case of raking wall intersections is keep the walls partially independent, at least during the design phase. Then the heights of the walls can be adjusted independently if needed...for example if the roof pitch needs to be changed. Either of the following would do:

If I really wanted to pretty it up later, I might put the roof on, group the roof and walls separately, hide top surface of roof, open wall group, select all, intersect with model:

A "routine" means a set of web Dialogs and Ruby scripts to make it easier to draw and edit wide walls.

Thanks for your advice. I think that is what we are going to do - "not worry about getting sloped walls perfect" and let the user clean them up later, if desired, or simply hide them with the ceiling or roof.

We are working on a new, free add-on for SketchUp, called RpWalls.

It has three basic functions:

Draw 1 or more wide walls in a running input mode, which will automatically turn corners and clean up the angles at the corners.

Here I placed two walls at angles, and then entered a height change for the 3rd segment.

Make it easy to cut holes in both sides of the wall.

Here I cut a hole in both sides of the wall, using a cursor set to the opening size:

The rectangle at the lower left is the hole cursor used to position openings.

When you place the "hole cursor" on the wall, the hole is automatically cut into both sides of the wall and additional faces are created to make a nice hole, all with one click.

Set attributes so the the Dynamic Components reporting system will report on the length of walls of each type.

Currently, each wall is kept as a separate group, so the can be cleaned up later.

For square corners, we will probably add an option to square them off, as in your example, with an option on the dialog to make the existing wall, or the new wall dominant.

The problem when you write a general routine is that you have to take into account several possibilities which won't be used often, such as non-perpendicular angles and having both walls slope.

Here's how a carpenter frames what you refer to as the "outside wall". A concrete wall would be treated similarly because it has to be framed in a logical manner with plywood or dimensional lumber.

Two angled walls meeting, is an unusual situation I have to think about that one.

addedendum: Here is the most likely way a carpenter would approach two sloping walls meeting.

Look forward to trying out that add-on! I often build the basic house structure in a cad app, simply because it's easier to build walls, make openings, etc...then move it over to SU.

I think, at least initially, having the wall corners not "tidied up" wiil be just fine. I often spend time tidying up like that only to find wall heights or roof pitches have to be changed...so a lot of wasted time

I guess when people start to use it, the feedback will start to flow, and the process can be tweaked as needed

Al,

Looks good, will it have the ability to create multi layered walls, most modern wall construction is mutilayered ie

1 Outer wall Finish
2 Outer Wall Structure
3 Air Space
4 Insulation Layer
5 Vapour Barrier Layer
6 Inner Wall Struture
7 Inner Wall Finish

some Hi tech walls have even more layers

Just curious and maybe asking for to much?

How would you present that in SU since it's not a solid modeller?

When RpWalls is complete, we hope to have a pretty good 2D display of the walls. And that is where the layers would come in.

Also, we hope to be able to report materials, so walls with different materials would report differently.

Also, with layers, you could turn off the drywall and brick layers and just see the base wall.

paulside

Sounds even better!

Currently I use the lines2multiwalls.rb ruby, which is great but it is limited to 4 layers, see attached image.

I eagerly await completion.

It's ready to try - See: RpWallMaker
