i'm going to switch to blenderbim in the immediate future. Thank for your passion. My question is: is it possible to do clearance clash too in blender bim? Thanks for answering
Unfortunately it is not yet possible to do this, I believe. I know that @vinnividivicci and fbpyr has been hacking on the IfcClash module - I think fcl can support clearance clashes using broadphase distance checking. Would either of you be interested in having a go at implementing this?
hi @Bimlooser , as @Moult pointed out, there are currently no built-in buttons in blenderbim, to do clearance clash. under the hood however, there are powerful tools ( like the CollisionManager from the collision module ) that can be used to perform clash detection of all kinds (I had written an add-on (BB-pre-refactor) that uses these, to check intersections of engineering pipes/ducts/traces vs. IfcProvisionForVoids). so depending on your setup it should be possible to also build logic, that checks collisions with clearance sub-objects (let's assume you have some machinery and their maintenance clearance area is blocked out by some boxes). hope I understood the question correctly. (-:
@fbpyr by the way, I believe the term "clearance" clash refers specifically to this definition in Navisworks. In other words, it is a distance check, not reliant on generated clearance geometry.
I see. @Moult thanks for link and explanation! (-:
well then it even depends more on the objects to be clashed.
a similar situation was, where we had voids in a building and wanted to know between which rooms they are located:
so I made extended (x and y 30mm bigger) proxy objects to ensure a clash with existing rooms even with less precisely modeled voids.
this might be something one could use to potentially do the aforementioned navisworks clearance clash.
Got it, i was referring to Navisworks definition. Thanks for the workaround, maybe could be something to improve for the future. Thanks for answering
In process piping models it is quite common to use the terminology Soft Clash. A soft clash could be access volume needed for maintenance, or need volume for travel/movement of equipment. These volumes are often modeled as 'soft volumes'
