groove in floor

[NERDASORUS]

hello 

what is the best way to create a groove on a floor with elevations like this one:

i need to create a groove from the 5000 point to 3000 point, the groove would look like this:

really appreciate your help

There are several ways, but how wide and deep is this "groove".  It might be too small a detail to model.  Might be better to represent it symbolically with just a thin line.  Know what I mean?  Keep in mind that with Thin Lines turned OFF, the "groove" might just look like a fat line in the view.  

...if you want too model it, a quick way would be to model the groove with a Wall Type, Join the Wall and Floor and then hide the Wall in the View.

The slab is 500mm and the groove is 200 by 200mm, i cant do the wall thing as i need to do a clash detection ..

[Yien_Chao]

does the groove needs to have constant depth? 

[NERDASORUS]

yes

[barthbradley]

Have you tried joining a Wall Type that is the same thickness as the groove is wide?  

...just read your clash detection remark. That's easy enough to fix.  

[Yien_Chao]

in that case, a simple generic face based extrusion will do. the extrusion must be a void. Then you substract the floor from the family.

ok, seems fair.
but how to make the top face of the wall aligned with the same face of the floor? because editing profile doesn't do it, neither "attach top/base"

[barthbradley]

Height of Wall makes no difference. It's going to be hidden in the View. 

...Wall Type Thickness is equal to the groove width. Groove depth is equal to the Wall's [negative] Base Offset.  

[NERDASORUS]

But the floor is sloped! And not in one way (could you check the picture I attached in the question please) so if I made it as you said the depth of the Grove could be 100 at one point and 300 at the other point!

[NERDASORUS]

Everything I've found on that subject makes the cut perpendicular to the surface ...

Could you give me a video or a tutorial on how to it, really appreciate it

[barthbradley]

Do you have Full Revit? If so, Model In-Place a Void Sweep pathed along edge and cut the Floor with it. 

...post your file. That would help us to help you better.  

[Yien_Chao]

wait, it works on a simple slope, but if i try to reproduce your example, the floor is not on a plan.

[NERDASORUS]

yes, here it is

Not sure what the issue is at your end, but another method would be to Copy Floor and Paste Aligned to Same Place, give it a negative offset from the other Floor (equal to groove depth) and then use the Wall Attach Top/Base Tool to attach the Base of the Wall to the Floor Copy.  Then Join the Primary Floor and Wall.  Afterwards, hide both the Wall AND the Floor Copy in the View.

Groove depth is consistent.

actually a straight diagonal groove between any two opposite corners

yes, exactly like that! mind sharing how did you do it?

[barthbradley]

sketch the wall diagonally.  Bada bing!
