Hi Roger,

> IS there any improvements on the Blend command?

There are no changes to the Blend command in this beta release.

Hi Marco,

re: MF2018.STEP file that gets stuck loading at 36% - I've got that fixed up now for the next v4 beta. There was a Solids++ function that could be slow to process certain kinds of trim boundaries. I've rewritten it with an improved version that does not get bogged down anymore.

Thanks for reporting the bug and sending the file for me to test with!

- Michael

You're welcome Michael!
Good to know that you have fixed that issue :)
Thanks.

Great loading speedup Michael. Massive speed benefits on my DualXeons also.
I got 3x,4x, and even 5x on some STEP models.

Kudos

Cool now also imports the colors of the objects, very well, great.

Sounds fantastic Lewis, thanks for testing it!


@pafurijaz - yes that Raspberry Pi board that you wrote about previously here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=8936.27
should be working ok now.

Greetings Michael thanks for the great update.
Pardon my ignorance, Please tell me how to use the the numbers followed by (ms) that appear in the upper left of each viewport.
Thanks. Cheers!!

<< by (ms) that appear in the upper left of each viewport

I believe it's just info for the moment of display's speed between each use of function ! ;)

Hi phlatt5th,

That's the number of milliseconds it took to draw the last viewport screen image.

It's used to compare the results of performance work to get a numeric measure of whether things are faster or slower instead of just going by feel.

It won't be on for too much longer, just until some last display performance work in v4 is done.

@ Pilou and Michael. Thank you for the clarification.
Cheers.

16Mb STEP file loaded into 3.0 took ~15 minutes to load. Same file in 4.0 beta took ~1.5 minutes. STEP file import, edit and conversion makes up the bulk of my work with MoI, so this is a really welcomed improvement!

That's great Branden, thanks for testing it!

Hi Michael.

Problem. Draw a curve of several arcs, connect, divide. Some arcs remained crooked.
Is it possible to solve this problem.
The file is attached.

Vladimir.

Hi Vladimir,

re:
> Problem. Draw a curve of several arcs, connect, divide. Some arcs remained crooked.

I'm sorry I'm not understanding what the problem is - I thought maybe you meant some operation was causing your curves to become crooked? But in your file it looks like they are starting out crooked to begin with?

Hello,

I notice a small oddity with the interface loading collapsed completely in the latest beta. When double clicking a STEP file from the file manager in Windows all of the menus are collapsed and the window size is something other than maximized. This happens for all STEP files. 3DM files do not exhibit this behavior when opened via the file manager. Loading STEP files through the MoI Open dialog works as expected.

Hi OSTexo, thanks for reporting this bug, I can repeat it over here too.

It's a side effect from STEP file import now showing some UI during the loading process, it will need to wait for just a moment until the main window is fully initialized before loading the file. Shouldn't be difficult to fix.

Thanks, - Michael

Hi Michael.

Look at the file, I changed it, maybe it will be clearer.

Hi Vladimir, I'm sorry but I'm still not understanding what to look for.

Are you seeing a difference in shape? In number of segments? I tried moving the curves on top of each other to look for variations in shape but all 3 versions seem to stack up exactly on top of each other.

Is it that the red curves are not detected as arcs in the last set? That's probably because they were arcs of very large radius values so they're very close to being lines.

- Michael

Hi Michael.

To work with CNC, you need arcs or lines, and here you get a curve, and in this place there is a pass in the CNC program file.
I do not want to use another intermediate program. If the fix is not rational then I will use three instead of two programs.
I'll solve the problem somehow. Thank you for your time.

Vladimir.

Hi Vladimir, unfortunately that's probably difficult to fix.

Probably what's happening is your original arcs don't share an exact end point where they touch, there is an overlap of length about 0.0003 mm between their end points. During one of the steps for your save/reload/join/separate process the endpoints for the segments inside of a single curve are getting trued up so they are exactly meeting end-to-end but that small change is enough to disturb an arc that is such a small piece of a much larger radius.

I'd think you could solve it by getting the ends trued up exactly by moving the last 2 arcs away and then moving them back with end object snaps so they exactly touch end to end before doing your other operations on them.

That's what I did with the attached file, does it behave better for you?
