Thanks for update. I know it a huge work you are doing - thanks a lot. Below, few my observations:
1) Autodistribution - good to have a choice to unlock each view from that and positioning it anywhere - There was a talk, but I don't know what with that happened. I just don't wan't to forget about that.
2) Good to have option to change accuracy of dimension in combobox - places after comma for each dimension. Sometimes usefull.
3) Disapearing line in dimension when I took value outside arrows - I think it should be still visible, at least could to have option to dissapear it.
4) Maybe if you off blockade to select only one part for view, will able option to display more of them - without using mux thing?

and my personal favourites:
5) Circle on detail
6) Welding symbols.

Having that it would be compleat fine enough IMHO to create most of drawings.

Great work anyway.

Edit: 7) There should be way to put additional point on drawing to which I could put dimension - for example when I have slot for dimensionig, there is no way to put distance between outlines of circles (o/a width dimension) in view from top.

Thanks for the kind words.
1) you should have a choice now for auto-distribute - on/off.
2) I seem to recall that you're supposed to use the same number of decimals for all measurements on a page. But it's been a long time since my drawings had to please anybody but me!
3) This is apparently a ISO vs ANSI thing. I could do a hack for now, but in the future we should probably be able to select from any "well known" standard. Maybe even "not so well known".
4) code could decide to use multiView if >1 part selected, I guess. Still have to know if there is >1 part internally.
5) this sounds familiar. soon. really.
6) I haven't given this one much thought, but can't you use the ones from DrawingDimensioning and TechDraw_Symbol?
7) This is on the list, but I really haven't given it much thought yet.

Often in the title block there are default tolerance for one, two etc decimal places. I use this simple workaround https://forum.freecadweb.org/viewtopic. ... 10#p148397

5) this sounds familiar. soon. really.

So I will "pile on"

6) I haven't given this one much thought, but can't you use the ones from DrawingDimensioning and TechDraw_Symbol?

Maybe just a custom leader?

Hi, two new issues .

When I insert multiple views, first press up arrow, then I get bottom and front (and back) view the same (see picture).
2nd thing on the detail view, I got wrong dimensions.

Could you add your model?

Regarding the "wrong dimensions"... You try to put dimensions on lines which were trimmed for the detailed view. Try to put a dimension between the two openings and you will see that it works.

Looks like your try to quote wandererfar did not work because you removed all quoted text.

Corrected.

Not needed. It happens all the time - try to put cylinder. Then multiple views. First press arrow up, then mark boxes (top and bottom view).

About wrong dimensioning, I made it deliberately. It cannot be like that it is changing dimension IMO. Arrow line should be broken from one side, but the dimension should be right.

There's a giant table to decide which views go where when the arrows are pressed. I was pretty sure there were still a few errors in it. Guess I was right.

2nd thing on the detail view, I got wrong dimensions.

I didn't know this, but upon reflection it makes sense. Dimensions don't know about "Base views". This will take some thought.

Thanks for the report.

I would think the base object (I mean part/... not programically) is the same... it should get it's dimensions from that, isn't it?

"True" dimensions come from 3D object, "Projected" dimensions come from 2D object. You could link the Projected (erroneous) dimension in detail to the actual 3D edge using TechDraw_Dimension_Link.

There's no way of telling which edge in the projection corresponds to a given 3D edge without manual intervention.

Hello wandererfan,

In another (old) topic I noticed issues with projections of a spring shape solid. https://forum.freecadweb.org/viewtopic. ... 10#p167103

I created a new file (attached) to display the issue. What I found odd is that the new model doesn't show the same issues as ulrich1a's original model made in 2015.

Third Angle Projection, default primary projection

If I rotate the primary projection left, the top projection remains unchanged, which is another bug.

Third Angle Projection, primary projection rotated left; the top projection should reflect the primary rotation but doesn't.

Furthermore, the Drawing Workbench seems to generate almost perfect projections.
