Trimming perfectly of pattern based tile partial at edge (still some remaining untrimmed)

[heichan88]

Hello,

following the past threads about roof, now the next problem is (which not been discussed in the previous posts), 

(1) still  some partial tiles unable to be trimmed perfectly, and

(2) the material (yellow/green) not inhered to the host family (blue)

my current tmodification is:  

- the profile is simplified (all profile is fixed hosted on AP1, while AP2 only adjuct the inclination)

 is that because the curve is too shape at edge so the profile reference point is out of control?

Please point out what is exactly wrong in the attached XXX.rfa (pattern based tile and the profile?)   many thanks

I do not have 2021 but I did check it in 2022...it seems to work fine except for the Profiles you used are Model Lines. You need to edit the nested profile >>> select them and check the box "is Reference" then they will not show once applied to the pattern. Otherwise give them a visibility parameter which can be used to switch them off

Why it is not clean cutting at your end...this I cannot tell since I am not able to recreate. Not sure if could be hardware issue (disable hardware acceleration, or a Revit version issue (I have never used 2021)

The tile itself...

• you seem to have picked the additive method to create the tile (ie: used several profiles to create multiple solid forms), 
• I would have instead used a subtractive method (1 solid form cut and carved by several voids)

for the material, make sure to associate the material from the tile to the host family and then apply it therein. You will need to do the same when loading into the project.

Hello, @RDAOU 

OK The  issues are solved with thanks as below:

（1） by turning off visibility the lines are removed. (my model need to off "is reference" to create form in the parent family)

(2) reset to no-pattern then reload again the tile patter, no missing at all （though sometimes missing 1-2 pieces which might because of PC memory)

(3) done by reset the material in parent family 

Many Thanks

Many Thanks!

Hello @RDAOU 

Another question:

can repeater of adaptive family on U-V surface be "partial"  at the cut egde? and be "offset" up 15 mm above from the mass surface? (seems no this function as in pattern)

if not, I make a liftup in the joist family.

Because I need to use this UV mass roof for other elements eg roof sheeting, vertical and horizontal joists

Thanks

In principle adaptive components can be cut and cleaned up along the edge but it depends on hoe they have been modeled. It is preferable that the cut does not cut-off a placement adaptive node, that's why many resort to modeling custom elements for the borders.

Not sure how you modeled the joists but if you would take the tile as an example, it would be ideal to model it as a 1xpt adaptive which makes it basically flexible when it comes to cutting because the placement point would always be hosted on the nodes of the cut surface. (yes, this is what I was suggesting on your other post with the drama)

hello @RDAOU 

for 1-pt adaptive, did you mean a past post mentioning an adaptive with many many divided points? it seems time consuming but if no other way then I will try this? Also I need to consider the quantity schedule which shall be one piece not many many short pieces in the quantity schedule. and any way to make it in an pattern based (small pieces if shared） then counted as 1 pieces when loaded into project?

anther long story (a pattern containing some types of elements in pieces, then combined in the project counted one piece for each type),  maybe I open another thread later to seek details...

Thanks

Thanks

I think we are talking about 2 different things... why not post what you have so one may have a look?

Hello @RDAOU 

In this past post once discussed a serie of vertical joist but each is 3 nodes curve, and once discussed if the horizontal joist can be divided with many nodes (though I later tried another way in pattern based by small piece, but cause quantity couting problem...)

https://forums.autodesk.com/t5/revit-architecture-forum/how-to-place-joists-along-u-v-curves-on-a-do...

in the case now, the joist is horizontal with many nodes of curve

Now the main roof is nearly completed, except the tiles at edge and right, I will seek expert advice later.

I am back in the office on Tuesday I can check how the tiles behave in Revit 2021 version...here I only have 2022 and honestly I an not able to recreate the issue of missing tiles. It could be anything from Hardware to a Modeling issue where Revit is unable to generate the tile when cut at certain angles. 

For the joists, I think it is best that you keep it on that post since you have already marked several solutions there which you seem to have followed. Less headache if you ask the author of those solutions first and if nothing works, I will be glad to help
