Latest work on Revit/Maxwell

[Wagurto]

I hope you like it! comments and critics are welcome
Thanks

[dpasa]

Very nice!
I'm a Maxwell user too and very anxious to see 1.5 (mid May)
How do you use Revit with Maxwell? Export to DWG and then with VIZ or MAX?
Is there any other way?

[Wagurto]

Yeah anxiouslly waiting for maxwell 1.5!
Yes for now the only route for me is revit, max, maxwell. Sometimes I used Revit SU and Maxwell but the first one in preferred
Thanks for your comments

Very nice!!! It looks like you are becoming more and more efficient in Maxwell...Congrats!

Wow! It looks like you modeled each and every tile on that roof!

[Wagurto]

Well, actually not. I modeled only the roof tiles that are visible for my angle view. By the way I used archicad for that task. I wish Revit will give us a tool like that. I know that for the purposes of CD's a hatch would do the trick but not for a Photo-real rendering like this one.

[dbaldacchino]

There's a way to create that in Revit. There was a post once that described how. It entailed using a mass and a curtain system, with a special mullio/panel family that was built like a tile. The reasult achieved was pretty much like what you have.

EDIT: Here's the post I'm talking about. Almost anything imaginable can be modeled in Revit!

http://forums.augi.com/showthread.php?t=29728Hi David the method discuss in that thread is not entirely the same as what is shown by wagurto the one modeled in archicad. That post only shows the modeled end piece of the tile roof but still using fill pattern to represent the groove of the second tile and so on and this will look flat in photorealistic rendering. I wish we could have the same tool as archicad to model roof tile exactly.

[dbaldacchino]

Hi Arnel,

Read through the whole post....the entire roof was modeled with a curtain system. All the families used were posted there.

Almost anything imaginable can be modeled with some workaround in Revit!

[Arnel Aguel]

Hi Arnel,

Read through the whole post....the entire roof was modeled with a curtain system. All the families used were posted there.David I've read the entire thread and I know that the tile is modeled using curtain system but not entirely correct if your look at the image (http://forums.augi.com/attachment.php?attachmentid=16934) here the tile at the next upper level is not protruding as compared to the previous tile below. The image just shows somewhat like a fill pattern to represent the protrusion of the upper tiles. Unlike the one modeled in archicad or max in this tutorial (http://www.robeccaproductions.com/Spanish_Tile_Toot_Page02.htm)which shows proper alignment of tile one end over the other end of the tile above.

[Wagurto]

Thanks for the max tip Arnel. I don't know if you have used the archicad tool for the roof or not but let me tell you just need to select the roof tile type (there are several available) then select the level of detailyou want and then select the area or plane of the roof you want to tile and that's it the program will do the rest. Later you need to add the ridges and hips guttters and other accesories. The whole task could take you about an hour or so. I don't think a Revit workaround will do it faster and better than that.

[Arnel Aguel]

Hi Wagurto I have not used archicad so honestly I don't know how it works but I can tell that archicad can model the roof tile correctly as compared to Revit's work around for that matter. I usually do my roof tile in max using the technique in the tutorial I posted or sometimes using vray displacement modifier.

From the sounds of your post it seems very easy to do that in archicad I would say we really need to have this kind of tool in Revit also.

[Martin P]

Why would not simply create a "two pick" family in Revit to do an edge roof tile?

[dbaldacchino]

Hi Arnel, I know what you're referring to. Since this method used a mullion profile to create the tiles, you get this extrusion shape with no ridges for each overlapping tile. Once again, it depends on the level of detail you want. If I were to do this I would take a slightly different approach. I'd model each tile as a curtain panel instead (with the correct rotation for the tile) and create a curtain system with a grid in both directions. This will achieve the result you're looking for. I think once you create the correct panel families, when you have to do a new roof like this, it'll be as fast as Archicad/Max since you just apply the system to a face or do a ruled surface.

[Wagurto]

Hi David would you mind to illustrate a little your method to do the roof tiles? It always would be better to do everything inside Revit.
Thanks

[dbaldacchino]

I'd be glad to, but at the moment I'm too busy to cook one up. I'll post one as soon as I get a breather.

Nice looking palm trees! I think the image might look nicer with some direct lighting illuminating the front of the house.

Although I would agree with the sunglight issue, I will say, the nice thing that this rendering shows about Maxwell, is the great way it handles the ambient lighting on the occluded face. If this were done in scanline (ouch) - this whole side would be in darkness. It's a very nice and realistic way of handling the bounced lighting.

I agree with you Wagurto - it would be nice to have some more "robust" modelling tools. I think the best way to handle topics like this is to make sure that you've (we've) outlined what the desired end result is to be and why it's important and get the topic off to the Factory through support requests, etc.

All in all, this is a good rendering with a good placement of the camera (other than the Sun comment). As a side question, what are you using for your vegetation/trees? They look like either Onyx or Xfrog's... I'm interested to see what is out there other than RPCs. I'm finding that it's pretty limited unless you've got a healthy budget.

Yeah, Yeah everybody's a critic.....:lol: :beer:

If this were done in scanline (ouch) - this whole side would be in darkness.The skylight multiplier (or enviroment light) could probably be bumped up to illuminate the sides in shadow so they are not pitch black.Using Gamma 2.2 also helps.

Lighting issues aside, nice job on the modelling. Looks very nice with the lamps and the detailed iron work.

One of the things I really love about the 'Physically-based' rendering engines, like Maxwell and Radiance, is that renderings look like photos because of this issue right here. That quality of light really adds to the overall 'depth' of the image I feel. Even the bad renderings done with this sort of system still look like photos, they just look like blurry and/or overexposed photos. :D

Well, I gave this a try, but I'm having issues at the hips...
Anyone know how to get around this?

[Wagurto]

hi guys thank you for your nice comments. The trees are from vue5 they are quite nice and very low poly count compare xfrog or speed trees. They are hybrid 3d mesh with texture mappings. I think the do the trick. I really do not like the rcp stuff or the just mapping techniques.
Irusun I feel your pain, That's why I would like to see a roof tile on Revit like the one on Archicad. That a breeze to tile a roof.
Yes, After tried several render engines, I found that maxwell its easer to use. I can achieve a real nice looking render without getting a master degree in other rendering programs.

[SkiSouth]

Here's a roof that is in RA8. I use this roof to insert, then simply use the eyedropper to select this roof and then turn what ever roof in the project I wish to be a clay tile roof. Sometimes, as irusun has found out, you'll have to tweak he grid, or ending conditions. You can see flaws in the roofing, but it is a quick approximation of clay tile without the hassle of individually modeling of each tile.

this is actually two roofs, one glazed, one underlay. Panels of glazed system are empty. This is a mullion based roof. The hips are handled by roof fascias offset from underlying wood roof.

edit - updated model to clean up hips.

[Arnel Aguel]

As Wagurto said that it is simple to create this type of roofing in Archicad and from the looks of this image (http://archicad-talk.graphisoft.com//files/temp_tile_138.jpg)I totally agree with him. Hopefully we will have this tool soon.

[dbaldacchino]

Nice Irusun...I wonder if perhaps instead of making them as curtain panels, you'd have better success if they were mullions?

[Arnel Aguel]

Nice Irusun...I wonder if perhaps instead of making them as curtain panels, you'd have better success if they were mullions?Mullions look promising but I'm not sure if it is possible as mullion is profile based family, is it still possible to have rotation angle for the mullion path? I might be missing something here.

[dbaldacchino]

No, I think you're right....I'm just too tired to think :)

[iru69]

I was just trying to do a proof of concept based on David's ingenious suggestion of using panels in order to get the rotation that gives it the realistic depth. It's starting to look like it can't be done with any sort of ease. It's looking like ArchiCAD is the clear winner here. :(

Revit is deleting the triangle portions of clay tile panel (at the hips) and replacing them with glass which is able to conform to the triangle. What is it about a glass panel that allows it to be cut to fit and doesn't allow the clay tile panel to be cut to fit?

[dbaldacchino]

I know, I'm kinda stumped. I wonder if it has something to do with the shape of the clay tile itself or perhaps because of the rotation (maybe try it flat?). At least we know it can do a flat slate roof ;)

I haven't given up yet....in a few day's time I'll play around with this (even though I'll never use it for the kind of work we do haha).

[iru69]

I did a little more research. Only "system" panels have the special pixie dust.

I think you can create a custom shaped tile and manually replace them at the hips and valleys... if you really wanted to.

[dbaldacchino]

So System panels ONLY adjust to fit the grid? Didn't know that since I haven't had the need to create custom panels (I only had to edit curtain panels in-place and add sloping mullions etc). I still have an idea up my sleeve using beam systems, but as I said, not right now :) This method seems to work great on rectangular roofs and fails once you get to angles.

That's right, System Panels are the only ones that auto-trim to irregular (read: not rectangular) outlines. Ran into this when working on a big complex curvy tower, the 'edge' panels that made up the curved profile had to be System Panels in order to work, while the 'regular' rectangular panels in the body of the curtain wall could be Component Panels. However, System Panels can be edited-in-place to make semi-nested in-place families (!).

Panel Families are weird. They don't really fall into cut-and-dried behavior like other Revit Families...

[dbaldacchino]

Thanks Jeff....I'll know what to look out for in the future. I've edited system panels in-place recently and had to add "mullions" (as extrusions) in there as you cannot slope just individual gridlines in a curtain wall. It was a bit of a pain but the CW wasn't too large.

[Lashers]

Thought I would post this here seeing that Maxwell is part of the subject (sorry if it is off topic). Have you guys received the MR1.5 update email?!

Current users will get their single licenses converted to 4 licenses (because they are currently allowed to use up to 4 processors with their license) and the 1.5 version will be workstation licensed but unlimited processors!!!!

Thats customer care!

It's looking like ArchiCAD is the clear winner here. :(It is indeed a clear winner here if archicad can do it I don't think that Revit can't do it. We should have this kind of tool and no more work around.

This could probably be done using roof based or face based family with tiles arrayed and with parametric void to cut the hip joint. Well, what do I know I'm not a programmer :?

[dbaldacchino]

You're onto something there Arnel....it's a workaround (true) but should get the job done. You can use the same method posted by Irusun (using panels for the clay tiles) but create rectangular slopes with no angled hips. So in this case, you would create 4 rectangular roofs by footprint with the appropriate slope and then, create in-place voids (roof cateory) to cut the edges to the angle/slope required.

EDIT: Hmmmmm very disappointing; it doesn't work. You cannot even cut the panels with an in-place void or a shaft opening. Revit will prompt you to delete the cut tiles (won't be able to make them) and replaces them with system panels :(

[Grumple]

Did anyone ever work this out?

Without having to spend hours on some rediculous work around... : |
