Hey,Michael, can you say pls when will the next beta come out?
Already have an estimated release date?

Hi blackboard,

re:
> Hey,Michael, can you say pls when will the next beta come out?

It will be as soon as I've fixed some bugs I'm working on. I don't know how long that will take, sorry.


> Already have an estimated release date?

Nope.

Greetings all.

I don't know if Im missing something, but does Revolve only work with positive angle numbers?
I want to do a 90 deg revolve of a circle to make a kind of elbow shape between 12 O'Clock and 3 O'Clock as shown in green in the attached video,
How do I get MoI to do that without resorting to use Rail Revolve, as -90 deg is ignored by the 'simple' Revolve tool?

Many thanks.
Martin.

Hi Martin, if you reverse the direction of the picked points that for the axis that will also reverse the direction of the revolve.

So like currently you're picking the start of the axis at the center point and then the 2nd point for it upwards along the z axis.

Instead pick the 2nd point downwards on the z axis to reverse it.

It would be a good idea if it did support a negative angle though, I have put that on my list to look at.

Thanks Michael, reversing the rotation axis picks points does indeed do the job. If you do have time to include negative angles, then I would certainly appreciate that.

Thanks.
Martin.

Hi Michael.
I've been helping out a prospective purchaser of MoI and he seems to have found a bug when revolving a closed profile. I've included a short video of the problem. If the axis of rotation is set very slightly away from the profile, then it works as expected.

Hi Martin,

re:

Currently the profile to revolve can only have one coinicdent line of contact with the revolve axis.

A case like this with 2 lines in contact would need to generate a solid with a void region inside of it. Revolve doesn't know how to make that kind of result currently.

To get the desired result, you'll instead need to have 2 separate profile curves like this:



Then when those are revolved that will make 2 solids. Then boolean difference can be used with the inner solid as the cutting object to make a single solid with an internal cavity.

Thanks for the explanation, Michael.

I've tried launching installer for this beta under WINE, but for some reason it fails - I get a blank, black window. For previous version it worked (but on the other hand I've updated the system since then.... at least I've tried running it in the same wine env).

edit: after some fiddling and switching to Wine 8 I was able to start the installer successfully. I've got the same problem with MoI4 installer, which previously worked correctly - so it's not MoI thing, but rather my configuration, WINE / Linux thing. On the positive note - after installing it seems to work beautifully , so I should be able to do some minor cad work when only my laptop is available.

Hello Michael,Do you already have a date for an approximate release of the update?

Hi blackboard,

Sorry no not yet.

I really want to create file new icons for commands in the interface, the most and naturally arising from this SVG icons.
The question arises, is it possible to use moi3d svg as icons

---

I believe that you must converter them in PNG images...

---

Hi blackboard, no the moi3d interface is not able to use .svg for icons directly, it is designed to use PNG images for icons.

You will need to convert your .svg into a 64x64 pixel PNG image and use the PNG.

Hello Michael!

How's it going? Hope everything's alright.

Have you some news about the V5 development?

Compared to V4 (that was a major rewrite at time) what are the advantages of this new upcoming V5?
And, last but not least, are there any current advantages to using the V5 beta compared to the official V4?
(I mean modelling speed, stability, better performance with Apple Silicon, etc...)

Thanks and have a good day.

---

Hi Marco, the biggest new things for v5 are - improved fillets using the ACIS library, Groups, SVG format, UI theme editor with dark mode, and native arm64 build for Apple Silicon.

re:
> And, last but not least, are there any current advantages to using the V5 beta compared to the official V4?

Well, the current v5 beta has all the above stuff in it which isn't in v4.

There is a collection of all the v5 beta release notes here:

Thanks Michael!
Very interesting the specific build for Apple Silicon. So, in the V5 build, are you directly calling Metal APIs?

I'm asking you about Apple Silicon because, for example, I would like to know if now I can set the viewport display angle to 5 instead of the standard 10, without getting slowdowns, thanks to Metal API and M1/M2 GPUs.

Please let me know.

Thanks.

Hi Marco,

re:

Using Metal APIs is a separate thing from arm64/Apple Silicon. But Moi v5 will also support rendering using the Metal API, it should be fully functional with the next v5 beta release.

In general I've found that the Metal API is somewhat slower than OpenGL so I don't expect that you would see any improvement in that area.

Despite its name and marketing Metal is a more "managed" display pipeline, there isn't any way set up to use the CPU and GPU in parallel for constructing a single frame in Metal unlike OpenGL. Basically it lacks any mechanism for dynamic vertex buffers.

Thanks for these info :)

But...this sounds me a bit strange.
As far as I know, OpenGL hasn't been supported (natively) on Apple computers, for years now.
All the GOU development has shifted to Apple Silicon and Metal API.
How is it possible that Metal can't deliver as much, if not more, as power compared to the OLD OpenGL?

This sounds really strange...
