BBIM: Make a simple construction sequence

edited February 16 in General

Hi everyone, i would like to make a simple construction sequence representing different construction phases.
The result would be like this video but it's not necessary to make a video, it's enough to realise like "static scenes" or "frames".
I would like to do it in Blender, not necessarily IFC but IFC it would be a plus.
Does anybody know if there is a tutorial or can somebody help me with this?
Thanks,
Massimo

  • I would be very interested as well.

  • You can do it with Blenderbim!

    have a go! IFC for free

    Thanks @Ace for the suggestion. It's a very powerful tool, i tried it but i need something more simple.
    I just need to show the different situation at different time and every situation should be represented in a different frame.
    Is there a efficient method to do this in blender?

    This is a very simple thing to do in blender, just see any animation tutorial. Basically you

    1. Select your object, go into the Outliner, deactivate the Show In Renders option (camera icon) and create a keyframe (i).

    2. Now in the Timeline move to the frame where you want your object to appear, go into the Outliner, reactivate the camera icon and create a new keyframe.
      See this for more details

  • Or if you're lazy like me and like to do everything with sverchok you can just chuck a frame info into list split and do it automatically.

  • And a bit less primitive solution using object ID set:

  • This is very nice @JanF and exactly what i was searching for.
    Btw, i tried the first advise you wrote and it's useful to say that the 'i' button (insert keyframe) needs to be pressed when the mouse is over the camera icon; also, it's possible to do the same with the viewport instead of render (it's necessary to activate the viewport toggles in outliner, the screen icon).

  • @Massimo I would use blender to show methodology and construction sequences for Tender Submissions. I've a pretty robust workflow that my team and I uses. I would be happy to go through it with you.

  • @CarpgianeDS hi! I would be happy to learn your workflow, btw it would be better to share it with everybody!

  • @Massimo that is my aim, but haven't gotten round to putting a tutorial together. I normally use IFC via BlenderBim as this is the format we would usually receive our models. I then animate the collection viewport and render visibility and usually have them at 50frames increments on the timeline. For texturing I convert the embedded IFC materials to nodes and then use the standard Blender texturing workflow. If you are using FBX or a Sketchup Import you will need to arrange all the building elements into collections similar to the IFC hierarchy. As an alternative to this you can also use different view layers to show each phase but I find this method quite cumbersome.

    This is all for tender submission's where only the visual representation is important for the quality score hence why it doesn't need to have any logic or be tied to a construction programme.
    Hope this helps.

  • Very nice @CarpgianeDS , this already helps!

  • I remember some some Navisworks workflow, wondering if this is possible in BlenderBIM

    • You could use planning software like Asta PowerProject to make a gannt diagram or something similar. Export a .csv.
    • This CSV could be imported in Navisworks and the coloured bars you could attached to the 3D elements.

    Was a very easy way of making a sequenced animation too. Is there any workflow or tutorial on how to do this with BlenderBIM and an open source planning project?

  • Hi @Coen , i know that with BBim it's possible to import file from P6, Microsoft Project and Power Project (see file -> import).
    In this video there is a tutorial about how to do a BIM 4d animation.
    Also, Moult did a very beautiful video animation demostration during last fosdem presentation here at 13:28.
    The workflow seems similar to what you have described, i hope it can help.
