It’s Important to deliver construction sequence to stakeholders with animation tools. it allows everyone to foresight constructed infrastructure towards it surrounding, plan method statements and prepare necessary action to execute the construction.

i found that twin motion is one of architectural visualization that could perform sequencing on construction. here are the steps to create an animation of your project construction :

1. Import all 3D object needed in your construction site.

(Import your revit file that contains : girders, super structures, sub structures, etc)

2. Import necessary twin motion library object that relevant to the construction such as construction sets .

(you can pick which groups have your needs and just delete object in groups if you don’t need one)

3. Create phasing stages using layers on/off switch on imported object.

a. open right pane windows by click top right arrow (beside eye icon) then on the lower pane click the drop down icon to select phasing.

b. click + button on the phasing pane to create stages (make as many as you want)

c. turn on each layers that needed to be visible to the first phase and turn off each one that doesn't then you may click cycled arrow to sync what’s on view pane to the stage

Fundamental : Phasing shows activity or objects visible in particular time therefore in every phase you need to set every object which are visible and not before jump to next phase”.

d. finish every phase by follow the instruction on point c (switch on only object you need to be visible in particular stages).

4. Create animation using video clips.

a. This function could be found under media icon on lower pane using video and then create.

b. Click create clip to start keyframe windows of your animation. (you can set the clip duration and daytime within the clip using respective icons)

c. create clips by moving your views to particular location and click on + icon in right clip pane to create moving camera animation.

Fundamental : Animation automatically created using keyframe of your view that move to the next location of your next clip so keep use that + button until you find the right camera movement and vistas.

d. create phasing by click on “more” text under clip 01 you create earlier on left pane. you’ll find camera settings > phase. pick respective phase towards the clip you want to show.

Fundamental : each clip has only one phase so if you need 3 phase to be shown you need to create 3 clips and set it phase to respective clips.

5. Render video

after finish phasing on each clips you may export the video using export button (lower pane, lowest icon) and click the video to choose every clip you want to export.

you’ll be provided with options on the quality of renders then Twin Motion will process the clips.

Here’s 10 sec animation that i pull out with Twin Motion!
