Grasshopper is much faster than Autodesk Dynamo

speed test of Grasshopper and Autodesk Dynamo:

more info about Autodesk Dynamo:



Rhino is also much lighter and faster than Revit, although the latter has more features geared specifically towards architecture and engineering (i.e. BIM, component libraries, etc.).
Already downloading Revit is a nightmare, since the installer is about 15 GB.
I’ve never messed with Dynamo, but it’s basically a Grasshopper clone right?
And Fusion360 is a clone of Rhino and SketchUp?

Rather than comparing Grasshopper to Dynamo, I’d compare it to Houdini, which does in fact some things better and is more robust when dealing with lots of geometries. However, the learning curve is even steeper as is the price! :wink:

I hate to say it, but I think Fusion is amazing.
It makes one realize how out-dated Rhino is.
If it wasn’t for Grasshopper, I’d long have sold my soul to the devil.

Draw a helix in Fusion 360.

Kinda claiming that a Honda CR500 (the widow maker, only for the brave) is slower than a CBR 1000 RR (ditto): the former is a MX thing the latter is a track weapon.

Meaning that if you are in the AEC market sector (BIM and lot’s of other things) you have 2 options: Revit + Dynamo or AECOSim + Generative Components.

But I’ve heared that 2 mentally unstable Italians would attempt to cross Sahara with … er … 2 Vespas.

You must be right, I only talk from my personal experience for artistic projects.
since you bring that up: is dynamo one of the only two options because it’s better/faster/more specialized than Grasshopper, or just because it works within Revit? (I suspect the second)

Do a T-Spline in Rhino 6

Your message is incomplete:
I hate to say it, but I think Fusion is amazing to me.
It makes one realize how out-dated Rhino is to me.
We see it differently…

OK then :
to me , in 2020, a CAD software that can’t deal with
-Interactive 2D projections of 3D models
-Face editing

is kind of lame, and I could mention the Soviet Union-era interface, but I won’t.

…and the horrendous meshing !

Your requests are specific to your job.
My job doesn’t need it therefore I (written in bold) find Rhino superior to other software.

The Soviet Union-era interface is a possitive… If it is simple and it works, don’t bloody “fix” it.
The other criticism is valid.


I do like Rhino interface too.
Absolutely hate monochromatic solutions like ArchiCad, it’s overdone.


Don’t you think they could at least answer this type of request ?

In AEC matters the forest is the BIM thingy - a must by Law in several countries (wait … that’s only the tip of the iceberg but never mind). So first comes the host application … then … IF you think that a parametric add-on has something (?) to serve (?) then … blah, blah.

That said a parametric thingy does some stuff in the so called preliminary (or concept) design phase: this means that if you think that in, say, the final phase we count on parameric … well … that’s the definition of optimism.

That said AEC is about solid modelling: meaning that Rhino is out of question by default.

That said BIM is wrong by conception: M stands for modelling instead of Management: correct should be BMDM (Building Meta Data Management). That said xml structured meta data that mimic data-bases … er … hmm …

I don’t like make comparison between softwares; the software is just a tool and everyone may use many softwares to create what he want in short time.
After all the result of the work speak


Yes, trouble is that several not very bright governments mandate the use of BIM, without considering the needs of different parts of the industry. By and large BIM is an utopian idea… And the model sizes… Jesus Christ that thing is heavy…

BIM is overrated in my opinion. It generates mess which appears to have order.
Humanity for centuries have been creating amazing structures without paper even and, suddenly, we can’t design single family house without BIM.


my hammer is better than your hammer. now pass me the nuts

Imagine doing an average tower that has about 2000 drawings (final phase) that belong to at least 4 engineering disciplines, that have 200000 pointers to specs (CSI MasterFormat Articles etc etc), that have 200000000 pointers to tech descriptions, that yield some sort of cost pre-estimation (in terms of millions or zillions). In serious countries that pre-estimation thingy is related with VERY unpleasant things if you did this, this (or that).

Then imagine that 1000 family houses are a small portion (cost wise) of the tower.

Then imagine the towers done only in China.

Then add plants, hospitals, admin, military, infrastucture. Count zillions and zillions of dollars then add zillions and zillions (and then add some more).

Then go to a PLM broad perspective of things: waaaaaaaay above BIM (thinking in the mean time these polar bears helps).

BTW: If you know what are you doing file sizes in a BIM driven pro app are VERY small (but not with Revit: that thing is a basket case for anything larger than a small house). Kinda saving 1000 same solids in Rhino VS saving 1000 Instance Definitions of the same thing.

Moral: BIM is kinda riding a proper Ducati: either you know what you are doing or you are dead in the next millisecond(s).
