2D workspace as in drawing space? If so its not really ideal for what you have in mind.Hi Alibre Team and blog friends,
I am trying to use more extensively AD 2DWorkSpace as Preliminary Design Concept Stage but I am crashing with the Profile's Region & Region Properties. I know Inventor has this tool being very powerful but AD doesn't. Some comment about.
Oh yes,2D workspace as in drawing space? If so its not really ideal for what you have in mind.
Hi Giov -- The "issue" is "2D Analysis" versus "3D Analysis." "Plane Moduli" values are best defined & derived in a 2D Environment rather than a 3D one. The Drawing module exists to provide a Drawing Environment and not a Design Environment. Now, if you check, my Libraries of "structural shapes" provide basic "Plane Modulus" values to make it easier to perform base (i.e."rough") analysis. -- LewOh yes,
When you do a mechanic & Structures calculation based in rules this tool is essential. If not, you only applies a part simulation but is not my stage because for example, I need a specific Area Section Modulus of one profile to obey a minimum requirement to go forward and not loss time.
If you have the area properties no only in 2D WorkSpace but also in the Part & Assemble WorkSpace Plane (as Section View) will be a minimum for my side. One option is implement Excel add-in in the 2D Workspace to carry out the (as example) Area Section Modulus but will be more difficult for composite structures."Plane Moduli" values are best defined & derived in a 2D Environment rather than a 3D one.
This sounds like a conversation you need to have with Max to understand what the intended capabilities of Alibre Design are. You may be getting into an area that was not intended or thought of.The 2DWorkSpace Region Properties is a essential tools for a "mechanic Software that pretends to be"

As far as my earth is not flat ;-), i've transposed your sketch into the 3D-workspace and extruded it 1mm thick (for the easy of "manual calculations") and used the physical properties...Look this Screen-pic that give an example that I am looking for:
I'm a professional user and have never considered the 2D drawing workspace as anything more than documenting my 3D models! If you want to do 2D based analysis, then use the appropriate tool (i.e. Rhinoceros!), not Alibre.When you do a mechanic & Structures calculation based in rules this tool is essential.
I also just get the properties for a 1 mm thick extrusion as per Stefan's example, it gives you the correct results, you just need to multiply by 1e9 to get the units to mm^4 or multiply by 1000 to get it in m^4 (if you work in SI (N, m, kg)).As far as my earth is not flat ;-), i've transposed your sketch into the 3D-workspace and extruded it 1mm thick (for the easy of "manual calculations") and used the physical properties...

This works also for complex shapes.
In addition the values of the physical properties calculation are accessable from AlibreAPI for further calculations (like CoG...)

Simon, Thanks for your approach:Not sure what your workflow is, but you're trying to do something the 2D tool is not currently capable of.
Sorry, no, you haven't understood. The 2D is a projection of a 3D object and the thickness could be infinite big...as I understand the 3D with thin thickness to achieve area properties
All (and somethings more) "translations" (scientic notation is standard in such calculations...) for you can be done with Scripting and this is not rocket sience...gives an high error margin (To translate all data as show Stefan & Hunter)
So don't waste more time and learn the scripting language to make your life mor comfortable...so the all workflow will be a waste time
I mean a thin Feature Extrude Boss.Sorry, no, you haven't understood. The 2D is a projection of a 3D object and the thickness could be infinite big...
I do not if will be practical to give the Area Section Modulus for complex structures iteration.....All (and somethings more) "translations" (scientic notation is standard in such calculations...) for you can be done with Scripting and this is not rocket sience...
AD must be capable of this essential task being that I have a good experience with the software but ever I am trying to do my little contribution for the right direction of its improvement. Do you remember the 3D point?! it was my request and you make fantastic achievement and for that I am so happy but other like cubicspline in Wizogrid wasn't yet achieved, or divide in points a curve spline or line in 2D-3D WorkSpace ...or the 3D curve (3D Sketch) in a assemble workspace for to be constrained as a movement path. That are some examples.Or, sorry, ask for concrete help, instead of saying Alibre isn't capable like others...
that's wellcomeI am trying to do my little contribution for the right direction of its improvement.
However nobody can help much without you telling us - the process to iterate, the best solution goals your looking for, the minimum rules requirements to follow, and the units you need it in.
try it again... ;-)! it was my request and you make
Like I said, this is a conversation you need to have with Max, maybe PM him directly to voice your concerns. For what it's worth, I'd like to see more functionality in AD but for my needs right now, as a hobbyist, it is pretty good. If I were using it as a business tool I'd likely push for more.I don't like AD team focus in cosmetics graphic thinks and not the essential tools that make the life better for its customers.
