@3DDave, Thank you so much for the input. That definitely sounds reasonable and doable, sadly it'll be me trying to convince someone of another document we should create. In the round about way I can just add the words installation instructions to a drawing format and push on.
As MintJulep...
I have a general question of drawing types (ASME Y14.24-2012) to be used for hardware assembly involving ground support equipment.
Basically the hardware used is designed to support and attach to an assembly or various other assemblies, but I need to define how that hardware is installed. By...
Not considering the Creo 4 result shown, which was troubling, it appears Creo 2 and 3 are reporting correctly. After chatting with PTC, Siemens, and Dassault it appears I came across a convention that not all CAD tool companies do consistently. I'm not sure why they don't just follow the math...
PTC might have some even more serious issues with Creo mass properties unless I'm missing something.
Given that it's now reporting an incorrect CG with the outputted result showing a negative Z.
CENTER OF GRAVITY with respect to _PRT0002 coordinate frame:
X Y Z 5.0000000e+01 5.0000000e+01...
I might be confused. Is the first quadrant in the negative Z direction given the CG has a negative Z value?
My first thought would be the first quadrant would be considered all positive.
Thanks!
Thank you for the reply. Looking at the Creo 4 results you gave is that the same example as I posted, a cube in the positive XYZ quadrant?
I ask because I see the Iyz as negative, so I'm assuming PTC fixed this issue and the geometry you have shown is different than the example I gave especially...
Has anyone noticed a issue in either Creo 2 and 3 (or later versions) that has the product of inertia showing the wrong direction (positive or negative)?
I've found recently that Creo 2 and 3 are reporting the incorrect sign or value (depending on the placement of mass) for the product of...
Yup that would be mine [glasses]
I've done all of the above, but Siemens states even though there are several ER's for this they have absolutely no plans to ever provide this.
I have ER's, posted on EngTips, posted on the Siemens forum community, and NX forum on LinkedIn.
I'm trying to see if...
Yeah I wish I could convince the NX 8.5 folks, but they are set in their ways, as shown by them still using NX 8.5. LOL
That's interesting I was just playing around with convergent bodies on JT's that, I guess, didn't have precise data turned on.
I was converting them into convergent bodies...
Unfortunately, I can't use JT. The suppliers/customers I'm dealing with request Parasolid.
Two use Creo 2 & 3 and choose not to purchase the JT license from PTC. And the last uses NX 8.5 and only wants Parasolid.
That would definitely be a nice addition as well. I tried Solidworks and it also exports curves via Parasolid and NX reads those in as well.
Sad how limited NX is with exporting a Parasolid when it is supposedly Parasolid based and the company who produces NX is the Parasolid license holder.
NX can import a Parasolid with an assembly structure that was exported by some other software that generated it.
What NX cannot do is EXPORT a Native NX or any model as a Parasolid with an Assembly structure included.
It can only Export a Parasolid as a flat file containing multiple bodies.
So...
I’m hoping I might get a poll from folks on this forum on the idea of Parasolid exports containing assembly structure. Siemens really only measures NX needs/wants based on IR generation, so the wants of NX users is probably not effectively captured if only IR’s are looked at.
Currently NX is...
Well the only way I know of keeping the curve broken and no indication of where it was linked to is the copy the exact same curve into the work part the link is apart of. Redefine the linked curve to use the copied curve. Then edit the link curve again and turn off the associativity. Then just...
Go to the part navigator where the unparameterized body is and right click the body.
You will see "convert to linked body" select that, then right click on the broken link to redefine it (edit with rollback or edit parameters) to a new reference body.
