Extend composite external wall skin down & cut slab edge

mthd

Hi, After many attempts of trying to use the complex profiler with a modifier to extend my external brick skin down bellow the finished floor level of a slab. I would like to know if it can be done without modifiers, using a similar method as is shown in this official training video posted below ?

 

https://youtu.be/3ttIpDmQVLw?si=zIzs09O6Tj9zJG4z

 

Can I just capture my wall profile and then offset the external brick skin down to the desired depth and then apply it to all ?

Edit: I tested it and it did work for me as an offset modifier this time. I think I was using the wrong type of modifier in all my other attempts.

 

I still need to figure out how to cut a rectangular rebate in the edge of the slab in 3D ? It can be done with the CI Slab Edge Tool but I wonder how to do it with SEO’s if that is possible ? 

Slab edge can only be splayed at this stage or can we cut a rectangle out on the edge as well ?

You don't need a modifier to stretch a skin.

You can just edit ti complex profile.

Adding the modifier just allows you to adjust the height (width) for individual walls that you place.

But if they are all going to be the same, no need for the modifier.

 

The only reason to 'capture' a wall profile is if you want to create a new complex profile based on standard composites.

If you already have a complex profile, just edit and save it.

All placed instances will update.

 

No you can't cut a rectangular notch from the edge of your slab without using SEO.

But there may be no need.

If it is a notch to recess the brickwork in, then so long as the brickwork has a stronger building material than that used in the slab, it will automaticall trim the slab away.

 

I actually include the footing and slab thickening in my wall profiles.

Your 3D diagram is like gold, I see what I need to do now. Yes my extended brick wall does cut the slab. 

 

Your footing is a complex concrete beam profile ? 

Thanks again Barry.

No, it is all part of the wall complex profile.

Has modifiers to adjust heights and widths of almost everything.

Cool ! So I could just draw a footing profile beneath the wall profile with a gap for a slab to fit under the internal skin like you have done here. Keeping the material of the footing the same as the slab.

 

Nice depiction of a detail to help me draft my profile. I have seen some other methods in videos but yours is the best one so far. I will try it out.

 

Thank you for your help once again.

I tested it out and it worked fine with a couple of little problems that showed up.

 

1) You see the footing line on the plan so I changed my external walls to cut only.

 

2) On my external walls where the reference line is on the inside to line up with a corner internal wall intersection. When I apply the profile, the wall flips. Do I create another mirror image profile to apply to that type of external wall or is there another way around that hurdle ?

1). You can adjust the 'Show Projections' settings as well so you don't have to set a s cut only.

2). Why do you need the reference line on the inside?

Walls should trim OK if inside or out.

Yes I will use the show projection settings instead.

 

Re: 2) Please see this post as to why.

Maybe create a Wish for being able to set the different Reference Line positions in Complex Profiles?

I see.

You can't flip the reference line of a composite wall like you can a composite wall.

But you can edit the offset position.

So offset it by the thickness of your wall.

Sorry, don't select and offset the internal wall as I have shown in my image.

I was just selecting them to show the reference line positions.
