re:

This method is not common in CAD but it is very convenient for simple drawings because you don't have to mess with setting scale factors to get a reasonable text size. With this method if you set it to have 12pt text, you see 12pt text on screen and it makes 12pt text in the PDF too. No giant text or tiny text.

Hi WN,

re:

Ok, that helps me understand now. Yes, I'll look at fixing that up.

If I understand correctly, you can use a workaround currently to get the result you want. The workaround is to initially place the radial dimension inside the arc's center point, then turn on edit points for the dim and drag the text point out like this:



But yes, it would be good to be able to draw one like that directly, I'll take a look.

What file format are you exporting to where you are running into this?

It used to happen when exporting to a polygon mesh format, but that should actually be fixed in this beta release. I happened to skip including it in the release notes.

Hi Brian,

re:

Well it can be a little different between different industries.

Here's a cool overview for mechanical engineering that OSTexo posted a while ago:

Hi Michael,

Yes, it makes sense. It seems that it's rather language issue for me then problem with funcionality :-) I feel th words "hidden line" as "invisible lines", i.e. lines, which are drawn by dashed line, therefore message "Generating hidden lines" was confusing for me :-)

Canvas megapixel resolution = 15

Thanks for explanation.

Hi Mik,

re:
> It would be great, because then we can avoid this:

Yes that's definitely not good!

That's what happens from me looking at dimensions all by themselves too much - the angular dimensions with little stubby extension lines look kind of weird all on their own but you need them for this type of thing.

I've seen in other CAD programs that you can put in expressions or formulas to be applied to the distance value to modify it. Something like this might fit in with that kind of thing but that's probably a ways down the road.

Nothing really specific yet, just that I'd like to make it possible to generate a drawing like you show there (not the detail view one though) all in one single export. But without having an entire paperspace/sheet parallel editing world. Maybe that can come in eventually too but it would be good to have something simpler before that.

- Michael

Hi Mik,

re:
> Canvas megapixel resolution = 15

Well that's really low actually so that's not the problem. You might want to bump that up to something like 50 or 60 or so to get some more accuracy if you find hidden/visible lines not quite meeting up properly. A higher value will also increase file size though because the shaded background image will be larger too.

It does do quite a bit of work so it's normal for it to take a while on complex files. It might be a good area to target for multi-core processing at some point.

No possibility to convert dimensions, arrows...in something to be "separated" ?

Hi Pilou,

re:
> No possibility to convert dimensions, arrows...in something to be "separated" ?

It is possible to do that by exporting the dimension out to PDF or AI format and then reading that file back in although you will lose the fills. But you can select the things that should be filled and use Construct > Planar to make a surface out of them.

What is it that you are trying to do by having the dimensions separated?

- Michael

Hi Michael,

very good FREE sw for dimensioning is Solid Edge 2D Drafting https://www.plm.automation.siemens.com/plmapp/education/solid-edge/en_us/free-software/free-2d-cad
and together with Make2D4Views script is effective combo for technical drawing.

... of course this is a special tool for technical drawing, but it could be good source of inspiration for MOI DIM tools.

re:
>Nothing really specific yet, just that I'd like to make it possible to generate a drawing like you show there (not the detail view one though) all in one single export.

IMHO it would be more than enough at the moment.

It would be nice to have command under fold DIM, which generate .3DM file with all set of views in one file, where the 3D models are perpenicularly arranged in TOP view for example, i.e. in opened model I highlight one part, which has to be manufactured = technical drawing, then I click to command and save it to desired place. TOP view appear after opening the file, where it will be seen 4 models in basic views, then I can import and scale the Table, see enclosed, and start create Technical drawing.

I think that 3D models are more advantageous instead of "Make2D curves", because PDF export offers at now many settings for presentation and if I need 2D curves, then I only highlight all models and run Make2D script, resulted curves can be export in DXF, for example.

Mik

Hi Brian,

here https://www.pdfdrive.com/technical-drawing-books.html is quite good source of Technical drawing books.

Mik

Hi Mik, so you mean making copies of the object and having them rotated and placed within your title block in the Top view? I guess the thing that would be missing from that would be having perspective for the 3D view.

I was thinking something more like in the PDF export dialog there would be a setting for doing 4 views, and also an option for a title block template which could be a separate 3DM file that you had prepared which would get merged into the PDF output. Maybe there's a named rectangle in the title block template file and the exporter fills in that area with that view.

That could be pretty simple to set up.

Maybe the other piece needed would be a property on dimensions to say whether they display in all views, ortho views only, or 3D view only... ?

I guess it could be for exporting to DXF format as well.

I'd kind of like to make it more oriented towards generating it all in one export instead of a Make2D-like generating it in a sort of "staging area", although Make2D could get the same behavior as well.

<< What is it that you are trying to do by having the dimensions separated?

Just to have total absolute complet control of anything! Number, Text, Arrows (part of them) etc...
Move, size, rotate, deformation (Flow) etc...more for design use than technical use...
(i can make yet all that with the Max Smirnov Dimensions but... ;)
Here just Move / Rotation the dimensions itselve for example


PS Your trick of Export / Import works also but some regulates must be done during the process! ;)
(unities, view...)


PS Seems there is something wrong somewhere : I don't success to re import in the same Size / View / Position
else dimensions, arrows and lines themselves are good! (except of course surfaces as you said above:)

Hi,

Sorry my bad.

The taskbar shortcut I was using was still invoking the previous beta release.

The current release no longer marks the file as changed on export of STL.

Thanks for fixing that.

Frederick

Hi Michael,

concept which I mean is based on Make2D4Views script, which generate 4 views (according viewports views I have set) like most technical drawings, pls see here https://i.stack.imgur.com/xwJwc.jpg or here https://en.wikipedia.org/wiki/Engineering_drawing#Line_styles_and_types

This script is perfect, but doesn't offer so many PDF export settings, like in case of solid/surface model, where I can change line styles, hidden lines are automaticly in dashed line style, shaded backround makes drawing more cool if it's necessary.

Therefore I copied and rotated model manually to achieve same arrangement like in case of Make2D4Views script, pls see enclosed.

Re:

It would be great! Do you mean that final 3DM will contain merged objects in 4 views + block template and then we can start with dimensionsioning or exporter will generate PDF with 4 views + block template, then we import PDF into MOI and start dimensionsioning?

Re:
>Maybe the other piece needed would be a property on dimensions to say whether they display in all views, ortho views only, or 3D view only... ?

Yes, it woud be fine.

Mik

Hi Pilou, for moving the text you can do that with a regular dimension by selecting it and turning on edit points using Edit > Show pts. There will be a point on the text which you can drag to reposition it. The dimension text will also automatically rotate itself to be legible in any view of it so you don't need to manually rotate it.

> PS Seems there is something wrong somewhere : I don't success to re import in the same Size / View / Position
> else dimensions, arrows and lines themselves are good! (except of course surfaces as you said above:)

Well the PDF/AI file only has 2D coordinates so when you read it back in it's going to be on the x/y "Top" plane.

For your case there you could do it like this:

Select dimension, export to PDF format using "Projection view: Right", "Scale: Preserve units", 1 units in MoI = 1 cm on page, and "Center on page" off.

Next run File > Import, pick your PDF file, then run Transform > Orient > View to view and click once in the Top view and then next in the Right view to reposition the dim back to the Front view.

<< for moving the text...

yes but the " text number " stays at the same place between arrows (who move too) !
It's not free itself till i Export / Import PDF ;)

<< Export / Import PDF - AI

Tricky & a little cerebral but Excellent!!!

THX for all!

Hi Pilou,

re:
> yes but the " text number " stays at the same place between arrows (who move too) !
> It's not free itself till i Export / Import PDF ;)

That will happen if you drag the points at the ends of the arrow line.

If you drag the point that is on the text you can move the text freely independent from the arrow line, here is an example:

Indeed! Very cool! I have picked the bad point! 1/3 :)

Else for the other one Export / Import (i have artificially lower position original for better see )
all works fine except
a little problem of text size... i have followed your info above but...(a bug or a bad options from my part?)
seems very small against the original! All was made in the same session!
I have Cm as Unities system enabled before draw something
not visible here because I have not add it after the <> in the Details' box

Hi Pilou, yes for text size to be preserved in this case you would need to set the option for "Scaling: By model units" on the dimension's properties.
