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.

Hi Vladimir,

re:

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.

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?

Hi Michael.

Yes, it helped. Thanks for your help.
Now it is clear what was the problem, I will continue to be more careful.
I'm sorry to have distracted you from your work.

Vladimir.

No problem Vladimir, I'm glad that worked!

Michael - do you have a date yet for when you will begin offering free upgrades to v4 with the purchase of v3? I'm learning the software now and looking to purchase in the next few months.

---

Hi Utopius, sorry I still don't know yet.

Hi Michael ...
Do you have an ETA for dimensions yet?
I have just finished a project that needed dimensions and notes and general adjustments and had to do it with alternate software, so the question arises again.
My apologies.
cheers,
eric

Hi eric, sorry I don't know for sure yet but I am hoping I can start working on it next month. It could be possible that what I'm able to implement initially for v4 will be too rudimentary for your needs, I can't guarantee that you will not need to use other software to complete your work in that area but it will at least be a step towards that.

- Michael

Thanks for the reply, Michael.
I'll try to curb my anticipation and enjoy whatever unfolds in the next months.
My method these days is to work with MoI for all the starting design and modeling and at some point to switch to another program to finish.
By that, I really mean to do the 2d working drawings. I am not facile enough to switch back and forth and keep my workflow smooth.
I do love the MoI process to get to the working drawing stage, though, and always am disappointed when I have to switch gears.
cheers,
eric

Hi Michael,

I detected an issue with construction lines in this version of MoI. If I draw a c-line, the anchor point moves away undefined from the point where I started to draw. I couldn't find this problem in preceding versions. I use the Mac version.

---

Hi jopo, I can't seem to repeat the c-line anchor point moving away over here.

Is it happening to you when you are inside a particular drawing command or in any command?

Does the entire c-line move around?

- Michael

---

Hi Michael,

it's happening in any command but not always and just the snap point is moving (watch the GIF) It feels like MoI would try to snap the c-line to the next grid point, but grid snap is switched off.

Hi jopo, thanks for the screencap that helped a lot. It took me a while to get it to happen over here but now I can get it.

I think it's a side effect from some changes in the last beta to try and stop mouse move messages from stacking up when working on heavier models.

It looks like you can get different snapping behavior from the mouse move versus the click if your click down spot is within the outer 1 or 2 pixels of the boundary distance where snaps engage or disengage.

You can probably avoid it from happening at the moment if you move your mouse just a slight bit more towards the snap point before you start making the cline.

I'll investigate a fix, thanks for reporting it.

- Michael

Hi Michael,

thank you for your reply. I tried the workaround you recommended above but it's not working properly. So, if I need the functionality a lot for some drawings I switch to a preceding version. And for the normal daily business i can live with it.
