Hi all,

Is there any way at all to get the walkthrough cameras to follow or attach to a controlled pre defined path???

You should be able to draw a circle, elipse, spline etc... and get the camera to follow the route - surely?

I don't see how else you can get a smooth, controlled rotation around a building for instance...

Any input welcome : )


p.s. - going to the mountains so won't be able to respond for a while !

Hi, (I want to laugh here actually but not at you).
No, there is no way to get Revit to host the camera on anything, sorry.
What programs allow this to happen please - just out of interest.

Lame...

I was under the impression that AutoCAD could do this???

This seems yet another needless flaw within Revit... You don't even have the ability to draw straight lines or curves, so how are you meant to get any REAL camera movement?

3D Studio Max works this way... A camera can be attached to a spline and animated to follow it over time. You can download a free 30 day trial from Autodesk's website. That should be just long enough to figure out how it works! As a bonus, Revit will export to .fbx, which Max can read, and all of the materials, sun position, etc. will translate too.

Actually, you can get very smooth results from Revit's walkthru path.

You can't actually "snap" to a pre-drawn spline, but it's very easy to place lines, arcs, splines etc. and then carefully place the camera keyframes on top of the underlying path.

With a bit of careful planning and placement of camera keyframes, you can get pretty good results.

That said, we also use 3dsMax, and Revit just can't compare--and it's not intended to.
If you want pro-level tools, use pro-level software for creating animations.

Revit is not strictly a visualization program--it's power is BIM. It does have a farily
good set of rendering and animation tools, for quick, simple studies where Max may be overkill.

Jayc,

Here is what you can quickly get out of Revit with a walkthrough path. This has three videos of a complete flyby around the building and up to the front door. It took around 22+ hours for 1400 frames. I broke this flyby up into 3 different pieces becasue it was too big as one piece. I just let it run over the weekend. This video has no post production in photoshop or any other video editing software other than stitching the images together.

Thanks for all that guys : )

I agree that Revit isn't primarily a visualisation tool, but would it kill them to enable lines and arcs when making a walkthrough?!

I am desperate to learn 3ds max - but don't have the time : |


Those actually look pretty good kirk - shame it takes almost a day to produce though!

The reason it takes so long is rendering time.

Revit can only use 4 CPU cores to render.

This is why (along with the other reasons stated above ) we choose 3dsMax
over Revit for photorealistic animations. With Max we can use an unlimited number
of cores with Backburner or distributed bucket rendering.

You should at least download a free trial of 3dsMaxDesign 2010 and start learning it.

cheers........

I have a student version : )

But I work full time 4 days a week staring at a computer screen, in college 1 day a week, and to be honest if I don't have homework to get done, I like to relax once in a while rather than attempting to teach myself programs after a full day at work...

Just don't have the time - without driving myself insane : |

Welcome to Architecture!

Wait til you start the path to getting your license!!!!!!

Hi,

When creating a walkthrough it always comes up with the frame numbers at the top left corner.

Is the a way to switch this off?

I'm probably going down the Design Viz route actually...

I don't have the patience, business sense or 'people skills' for the architect game!

No idea about the frame count thing... good point tho...

Not in Revit 2009. I don't do walk-throughs, but it is my understanding that in Revit 2010, they no longer put the frame numbers in.
