Greetings.

So here is a curious condition, but a real world situation, for which I'd like to find a work-around:

The grade at the perimeter of the building rises and falls ... we have a typical detail for terminating the wall finishes at 200mm above grade, as shown in the attache PDF.  Is there a way to control the elevations such that the base detail will follow the grade (as establiched by a toposurface)?

The T.O. foundation wall is a constant but the grade is not.  I have created a reveal to mimmick the flashing/base condition. 

• I can drag each wall (finishes layers) up and down but they remain horizontal. 
• I could break the wall here and there to accomodate the changing grade, but the result will be 'stepped' and I will end up with many more walls than seems reasonable. 
• I can edit the profile of each wall but that would have to be after the grade is 'set'
• I'm not sure if Split Face will allow me to continue the finishes ...

I am open to any ideas and suggestions.  Thanks in advance.

Ian

You don't need multiple walls to step the bottom, simply edit the profile of the bottom of the wall to step it at the intervals you want.

You can not get the wall to step automatically.  Instead, cut a section along the face of the wall so that you see the grade line and can adjust your steps accordingly.

"i thought this meant he understood the profile option,.

i think we both better get a life.

Gentlemen.

I thank you for your banter.  I do appreciate coreed's defense of my understanding of the basics ... and we all probably need a life :o)

WW, I appreciate the suggestion but to coordinate the bottom of the wall with a topography that flows as much as mine do would be as much a task as splitting the wall.

I will however, try the approach of carrying the finish thru to below the grade then near to the end of the project use the Split Face routine to 'paint' a 200mm band that steps along with the grade to 'represent' the separation of the wall finish from the earth. 

As much as I want to model EVERYTHING I need to remember that I am not building reality, just modeling it. 

This might be an ambitious wishlist thing to assist with this ... a feature that will allow me to set a min/max distance between the wall finish and the adjacent grade.  It is a real-life issue that architects need to deal with for many reasons - especially in a wet climate like Vancouver or Seattle. 

This was not an issue with traditional 2D drawing because we just drew the general detail and elevation without the accuracy of the Virtual Building.  Now that there is such accuracy, I don't want to give the contractor an 'out'. 

Thanks again for your input and I am still open to more suggestions ... (since I have no life ...)

if that's the case,i have been pondering the thought of adaptive points/components and grading. constrain the adaptive grade to the wall and when the wall move the grade automatically adjusts.

Good Luck with that one.

interesting thought, but I'd still allow for the grade to control the wall (finishes) as an option.  I can see this being useful in either direction. 

My work responsibilities are pretty heavy these days so I'm not quite ready to go after such a goal but if you hear of this happening, I'd appreciate hearing about it. 

Thanks for your input.  Sincerely ...

Ian
