This looks like a very clearly explained answer.
Thanx so much will try this later.......hope u stay tuned I will let you know how i do/problems i face, and maybe take a look at the file when u can.

You must perform the intersect within the context of the faces that you want intersected. If you do it to components or groups the edges will be created but they will have no effect on the faces. So open (edit) the group to where the faces are select-able. You don't have to explode the group, just edit it. While in edit mode you can also erase parts of the walls that you no longer want.

I cannot open your file right now, but as for layers--they should have no particular effect on the intersecting faces command. The important factor is the context (for example inside a group or component) that contains the faces.

Use the layers for visibility or hiding the groups. Keep all your edges and faces on Layer0. Group the ones you want making walls and then assign the group to a new layer. Group the faces and edges making up the roof and assign that group to a different layer. Then unchecking the visibility for the roof layer that group will not show.

The edges and faces are still assigned to Layer0, but the group, which they are in, is assigned to the new layer and visibility of it is controlled by the new layer.

You can do something similar with the new bedroom walls if you wish. And that could have a separate component or group. All the wall components can be assigned to one "wall" layer or they can each a have different "wall" layer--if perhaps you want to hide the bedroom and not the rest...etc. Similar if you have more than one component making up the roof areas.

Always keep Layer0 as the "active" layer.

Hi there from Chiangmai Thailand

SKP file attached.

I want to intersect the roof with the chalet.
I have made dotted measurement lines and put the roof in exactly the right spot and angle.
My next step was to use the eraser and erase everything above the roof.
I havent done any Sketchup a long time and made more or less the same model in Sketchup 8 until i realised it was out of date and started again with Make.
Thing is when i did it before I was able to erase above the roof.

What did i do different?
Not 100% sure, but at some stage I grouped and layered both house and roof, but when i had problems i have tried to unlayer and maybe ungroup.

Fact is I'm confused and maybe someone here will see in a minute or two what I have and haven't done.

What I WANT is to have a model of the chalet with roof, but be able to disappear the roof to see and adjust the inside of the chalet, put in the doors, windows, kitchen etc
I then want to add a small lean to bedroom to the high wall which I was thinking of making a group same as the roof and attaching to the side........would also like to be able to disappear this as I might build it later.

Any advice most gratefully received!

Hey Dave
I managed to get a decent picture out which served perfectly for our little meeting (we are condo committee members here in Thailand organising renovation of common areas.)

I used follow me and it worked fine on the rail.
Just could not seem to get it to work with the glass but drew glass out from both sides and they met good enough for quick scrutiny, though if you look closely at the join in the glass you will see it's kinda overlapping. ......
uploaded according to your advice

Would it not have been possible to highlight both the rail AND the glass and follow-me them together?

Thanx again!

Thanx for your time Dave
It's late here in Thailand and missus calling me to bed much as I'd like to have a crack at sorting this.
I shall try your hints in the morning please stay tuned thanx!

That's perfect Dave.
Could you throw me a bone or two on how to do it?

ps: I see you have sent a png file.
I'm guessing it's much smaller and quicker and of course will display with your post.
How did u do that?

To add......I have now replaced walls at the entry end of the long hall with glass.
Well.......I reduced the thickness to 10mm and filled with a pale green colour same as I did the glass panel under the rail in A. Funny thing was, one of the two "glass" walls ame out transparent and showed what was behind, while looking quite good.
Why did the other glass wall and the panel in A not do this?
(I'd like to put glass in the big window space in the main area too.)

Check the SU pic and see there is a gap in the wall with a rail and glass.....A
There are two more reveals there neighbouring, B and C. I want them to have the same theme as the first, rail and glass. Obviously the third, straight one is like the first and no problem.....though it would be nice if there was a way to kind of "copy" the first ail in A.
The middle space B has a 45% (roughly) angle in it (I have stuck and upright line there for the rail to go to before angling but realised it need and angle on the end not 90deg.
I want to sketch in a stainless rail about a metre high, then in the space below, a glass panel.
So the rail will go about a third way across the gap, to where the angle happens, then bend towards the next side of the reveal. Same goes for the glass underneath.

How will I get this done easily?

Thanx!

ps: possible to make the glass look good?
pps: is there a clever way to just click something and continue the rail and glass theme in A to B and C?

So, by vertical you mean the z axis then yes you can make vertical constructions. If you mean perpendicular(normal) to the model surface, you can do that too.

THankyou Mitcorb...
the question is.....how? I'm talking about Smoove here for shaping the land. Seems to me a surface can only rise from one line on the grid to the next line on the grid. And say that line is one metre or whatever it is away.....so if the rise is for example 2 metres how can it be vertical, it's an angle whose TAN will be 2 isn't it?
This is one reason I asked about my max number of grid lines for a 2gig Macbook, as the grid size affects my question. My land "triangle" has sides about 60 metres or so, so if I spread out a bit further to incorporate neighbouring houses and land shape, a 1 metre grid (nice) would have maybe 120 or 150 grid lines on both x and y directions. I'm guessing that's way too much? But 1 metre spacings would give nice shape to the fairly small river.

Thankyou for your comments about groups and components etc. I had already half figured I need to make the land one group and possible buildings separate components to try stamping (a new skill I'll try), correct? (I don't have contours or any other program....just an amateur).

To make things more real, less dry, and perhaps understandable I'll upload some pics.
The first looks at the wall on line AB
Second the track about 140cm above the base land level
Third the river down some way from the track
Fourth the view just to show you why I want to live there.....

cheers Cheeryble

sorry photos not showing try again later
