I apologize in advance. For some things I'm interested in deepening, for others I'm not.
If I may, ask a question. I have a M1max with 64GB of RAM. Sometimes I see that I struggle to do navigation and, above all, sheet layers and section viewports operations.
Does it make sense to spend almost 8000 euros to take an M1ultra and wait for it 3 months, in the meantime comes ultra m2 or m3, extreme, planetarium, extramporalis, super Sayan level V processors?
I know it's a simple question, maybe from newbies, but sometimes simple things are the best.
(Obviously if you want to tell me which trades is best for and for which it wouldn't change much)
Thank you
I'm still getting to know this Ultra but I'd say you're in a good spot to wait and see what's announced in the second half of this year. What you're missing right now is faster renders with RW. I would say the rest of your workflows are probably the same speed / performance as this studio because of how the ARM SoC's scale.
Personally, I decided to commit to the Studio because the Pro seems to be delayed, and I needed the fast Mac I could get my hands on right now. I don't have any buyer's remorse, and honestly, it's more about software developers optimizing for M series, so our M1 computers should get relatively faster as the software we use everyday gets more optimized (kind of like when NVIDIA release a new GPU on day 1 vs a year later).
The other factor that went into my decision is that I only need a laptop 10% of the time, so I'll keep the old MBP around until there's a 15" M2 Air or something. Everyone's needs are different but I'm glad I doubled my multicore performance 90% of the time.
My next purchase will hopefully be a M2 Extreme with 40 cores (in an enclosure that fits my budget). However, what's more critical to me is hardware accelerated ray tracing for UE and TM. So, until that's available, I'll probably stick with this Studio.
Btw there's an eponymous law (like Murphy's or Moore's) about perpetually waiting for the next tech (particularly Apple devices). The name escapes me but if anyone is still on an Intel machine from 2015, just get the best option that's available right now. Especially with the chip shortage and general supply chain issues. I sold my unboxed MBP M1 Max for the same as I paid for it 4 months later, and the buyer said that people were scalping them for $2000 USD above list price. Mac's hold their value, so you can always sell it when something better comes along.

Oftentimes VW could only use 1 thread of each core, so it would be utilizing 10 threads (but the other 10 threads were idling)
No, VW offentimes can use only a single core, as there are threads in CAD that can't be
separated into multiple threads as they need to be calculated linearly and everything
else has to wait for that result.
But you can use those other free CPU Cores/Threads for iTunes, Mail, Safari, .... during
that time.
I'd have to dig through screenshots but I can definitely show you VW using every other thread.
-
What I'm unclear on is that the M1 Ultra has 20 cores but my Intel 10-core chip had 20 threads. In Activity Monitor, the graphical display of those 20 cores/threads looks identical. For context, I was expecting to see 40 threads when I jumped from 10 cores (20 threads) to 20 cores.
The nice things about this are:
- Every M1 core is the fastest single core (not just one of them that has been boosted)
-
Oftentimes VW could only use 1 thread of each core, so it would be utilizing 10 threads (but the other 10 threads were idling)
- Well, thinking this through a bit more... no change here
I'm not an expert but I think this sort of explains why the Ultra is getting beaten by the Intel 12900K (both single and multi core) and destroyed by 3-year old AMD Threadrippers in Cinebench (which will use every thread). Put another way, the M1 Ultra is more like a 10-core CPU with 20 threads when comparing Apples to oranges.

I agree.
I can import RVT or IFC much faster in my other CAD.
FBX export from VW was usually OK for me, beside that if the file is too large,
VW will save an empty FBX file.
Yeah, so I think the takeaway here this that the additional cores in the Ultra aren't helping but the additional memory might be.
Keep in mind, single core performance (of any of the cores) is pretty much the same across all M1 SoC's (from base model to Ultra). -
FBX export was slightly faster.
I suspect if I tried exporting the same file on my 2019 MBP, I either would have had to wait even longer or force quit.
For some reason / reasons file import/export has always been an issue with VW, especially on a Mac.

Experiencing my first sinking feeling "gut punch" with the Studio...
Exporting to 3DM is hardly taking advantage of the hardware, so it's taking forever (not to mention collapsing everything to 1 layer for my design team to sort out).
Here's Activity Monitor CPU underutilization:

I think the filename actually has to be "__@2X@2x.png" to work:
However, even after changing the filename, I get the following error message:
Even though the file is the correct pixels and, presumably, DPI:

12 or so years ago I used a Razer Nostromo gamepad for this (now it's the Razer Tartarus, nicer but same button layout). I'm left handed, but use a mouse with my right hand, so it worked really well for getting away from using the keyboard. I recall it having 7 or 8 different layouts per application, so I had it set up that I could roll through them with the scroll wheel and had a different layout for different functions (one for views, one for data entry / basic tools, one for 3D modeling, one for Spotlight, etc).
I used it extensively for two years or so until I got a new laptop. The profiles are now tied to the cloud, but they weren't back then, and I didn't feel like rebuilding the profile. So I put it in a drawer, where it lives to this day.
I was looking at the same things...

This is the device I was using. They probably don't make them anymore.
It was a big improvement in my workflow. I'm primarily lefthanded but use a mouse effectively with my right hand.
The ergonomics of an extended keyboard with navigation keys on the right almost requiring you to let go of the mouse to operate them is counter-productive.
Can't tell you how many times I've tried to become a left-handed mouse user, so I can use a typical (right-handed) full size extended keyboard.

There is this company I started to do work for...they are 99% mechanical so I recommended Onshape. They were going down the Solidworks route.
How does Onshape compare to Solidworks when it comes to file interoperability with VW (being that VW and SW are both solids vs mesh-based, and built on Parasolid)?
Is Onshape mesh-based?It looks like Onshape is also Parasolid: https://en.wikipedia.org/wiki/Parasolid

See those doors in the image? They are parametric. Not parametric like we are typically use to (OIP). But truly parametric stuff that you set up yourself to do exactly what you want...no need to wait for someone at vw to fix/imporve something for next years version...
This is an excellent point. I'm beginning to think that many of the stock parametric PIO's are just a starting point for new users, and that I'm better off modeling the objects myself (like Rhino) because in the end, the stocks tools only get me 80% of the way there, and then I go down a rabbit hole of trying to find a workaround... They're a blessing and a curse but we don't have to use them. This is especially true of the ones that have been abandoned over the years.
Model it, slap a custom record on it, keep moving...

I mapped out the dedicated hotkeys in an effort to find some gaps. There are definitely some weaker ones that I'll never use that could be replaced (although I know that won't work for everyone else):
The blue rectangles are the default resting finger positions. The ";" is only for Windows. I just discovered the "fn" key is a hotkey for the Mac Character Viewer aka Emoji's etc.
I tried restoring Snapping modes (yellow keys above) but fell short because of R and F (and that Working Plane 3D mode that wasn't a hotkey option before):

When I was using an imac and the keyboard without the numeric keypad. I was most happy with having purchased an inexpensive keypad that I placed to the left of the keyboard. It had the arrow keys, home, end and a forward delete. No longer was I bumping into an oversized keyboard with my mouse, nor having to release the mouse to press the navigation and view keys when my left arm got tired of reaching over to the right side numeric keys. And I now had an enter key on both sides of the keyboard even though there are some functional differences between return and enter.
I have been thinking and looking for reasonable priced option for scripted keys for some time. I recall when I first started drafting in the early 90's on Autocad that in addition to keyboard entry many workstations had a graphic tablet with a puck for input and those tablets had flexible and programmable menus. Plastic overlays to identify different functional areas. Menus that could change depending upon the current context or a modifier key was being pressed.
Somehow a lot of that functionality was lost or ignored when magnetic tablets went to the grave and these new touch screens simply have not caught up to the past. Or at least not within a typical workstation budget.
I've been using this setup forever:
Experimented with this expanded numpad for awhile but it's a cheaper crappier version of the one in the pic (might pull it out of the drawer and give it another shot):
This is what got me thinking about a macro pad...

I guess another thing, and this is why I like numpads and macropads is I'm a touch typist, so I don't want to look at the keys, so ideally would feel keycaps
-
I'm working on a solution for a couple things:
-
Only using my left hand for
- Views
- Hotkeys
- Tool modes
- Mapping the 4 lower views
- Remapping UIOP[ ] because the mouse is attached to my right hand like Ash's chainsaw, so I never use them
-
Restoring (and possibly remapping) the Snapping Modes hotkeys
- Which are also cool because double-tapping them brings up the settings for each mode
Note: at this point, VW is the must-have; other apps are a nice-to-have / "let's see where this goes... "
I'm looking for input (pardon the pun) based on others' experience with these doodads, including other hotkeys that are underutilized that I'm overlooking. I'm not interested in shortcuts.
Here's a discussion about using these for CAD:
Here's an example of a Macro Pad that would use the default keys:
Here's what I'm thinking for mapping the Macro Pad (1 too many rows for a Streamdeck XL):

Here's what I'm thinking for a Streamdeck but I would lose the hotkeys (less concerned about the arrows):

Finally got to scratch the render itch.
Rule of thumb for these specs: Realistic is as fast as Preview used to be on the Intel MBP in my sig.
In this case, Preview Spotlight takes about 30 seconds for this scene, and Realistic Spotlight took about a minute and half (previously 5-10 min). Time stamp is in the screenshot below. This is on the design layer for a projection clipping study, so it's not a client-facing published viewport with RW camera, 300 DPI, and all the fixin's.I was hoping that Preview Spotlight would feel like "real time" but it doesn't really function that way. It's more like a stop-start... rotate or pan view... stop-start.... vs what we're used to with Shaded or TM/UE. In hindsight, that makes sense because each scene is "baked" with RW. If anything moves are changes (even a class visibility), the scene has to bake again.
Looking forward to testing this with more challenging renders this weekend...
Ugh... upload failed (again).

Thank you very much but still simple geometry speakers with a symbol when re-built...
I think it's a binding problem between Symbol and Catalog/Library ?

Thanks again
Could you post a screen recording of the workflow?

After 7 years, I've finally worn through the top layer of my 3Dconnexion mousepad, so it's time for a new one.
Does anyone have a favorite / recommendation?
Would love a larger (gaming?) footprint...

Personally I tend to convert my pipes into truss objects to get round this issue and then use the criteria object using parameter, Truss, Name for my data vis as this parameter normally a combination of the truss type and length.
That's a great point. Ever since watching @markdd's tutorial, I created a library of pipe symbols (stock lengths) that are converted to truss objects. I almost never use the pipe tool by itself.
-
Also, as someone that's battled truss data vis in worksheets, I discovered that records are the most reliable (fewest issues) to use data vis. Symbol names can be problematic, and never use classes.

also , anyboone know why in the report the img by data vis works for truss elt but not for pipe (ex50...)
Does the pipe have the same record?
BTW one solution to all of this is to create a custom record that you apply to as many objects as you want: truss, pipe, clamps, hardware, hoists... By using the same custom record, you only have to create 1 data vis rule (vs the same rule for each record). If necessary, you can use the Data Manager to refine that with mappings, calculations... That might sound like "a lot" but I find the stock stuff is a starting point but you're limited to the records provided (and which objects have which records but not others). Once you customize the record, you're mostly limited by your own imagination. And you definitely have a good handle on this stuff based on the posts above.
Mac Studio & M1 Ultra
in Hardware
Posted · Edited by Mark Aceto
TL;DR
And, remember, that number is combined RAM and GPU, so you can't compare 16gb M1 to 16gb Intel (for a lot of reasons). And I'm still waiting for someone at VW to officially confirm how many gigs the GPU can pull from RAM. My wild guess based on absolutely nothing is that it's split down the middle: 50/50.
I would say the additional RAM in the Ultra is a nice-to-have. A maxed out Max is a great Mac for most VW users.
If you're a heavy RW user that can take advantage of (double) the cores, you know who you are.
Btw I have iStat Menus running, and I would say no app developers have figured out how to optimize memory usage in these things (including Apple). Sometimes I'm using 50% when I'm barely doing anything (VW is closed). Meanwhile, right now I'm using 22% and VW is open in the background (has been for a few days). It's kind of a new frontier right now. I imagine a year or two from now, things will level off.
