Thanks for a clear and concise tutorial. How about the display of the measurement itself: it's not obvious to me how to alter the places of decimal applied to a dimension?
Weird thing: I have no "gray vertices and crosses" when using techdraw (FreeCAD 0.19 tried on Linux / AppImage / Windows). Any idea on how to activate them? Am I missing something? It makes the module pretty unusable, especially for the center marks... Thanks!
Techdraw has a ton of settings that affect visibility of elements. Check especially the view properties (view tab in tree) for the various selected objects
Thanks for this valuable piece of knowledge about FreeCAD. Neverthless with the latest 0.19 version I am not able to draw the dimension in the isometric view as you are showing in the video. The extension lines are not following the isometric axis, but they are perpendicular to the projected line. This is method is consistent and valid for the 2D projection, but can be ambiguous in case I need to put dimension just in the isometric view. Is there any option in the techdraw module I am missing?
Also i think it is very different how you give dimmensions in 3d designing ang in manufacturing. In desing 10 mm is 10 mm. in manufacturing 10 mm is somewhere between 10.001 and 9.995 depend on your tolerance.
@@VladiFx I had a big reply that apparently went out into the woods. The design and maufacturing dimensions should be controlled by a drawing standard. That doesn't mean that constraints should be directly copied but they should be copied and then modified by the drawing standard whether ISO or ANSI modified for the companies particular practices. It bothers me that there is apparently no linkage between the design and a drawing. If you change a design as far as I can tell you don't even get flagged in the drawing.
@@VladiFx of course they are different things. But when you change your design, i.e. your constraints, is your drawing then worthless? If you parameterize the constraints on a sketch, what happens to the drawing. I am troubled by the lack of linkage between the design and drawing. It seems pretty primitive to consider drawings just snapshots. How would you keep track of changes. Ugh. At least flag the drawing when the design changes.
I use the "Hole" function with the PartDesign workbench. The function itself is very useful but how do you get the right markings later in the picture? Let's take three cases: 1. Through hole with M3 thread. In the drawing I want to have the M3 designation e.g "M3 thru" ..... I know I can add the right symbol but this is not the right way . 2. I have a hole with a depth of 12mm with an M3 thread. How do you get such a mark in the picture e.g. "M3x12"? 3. I have a through hole for the DIN912 M3 screw with a socket for its head. And again the alpine combination with the marking of such hole... e.g. "M3/Φ6x4,5" I will be grateful for showing you the right way without using additional pictures.
Call-outs and symbols are still pretty limited in 0.18. There's work being done on this right now in the development branch. I strongly encourage you to read and and contribute on the FreeCAD forum in the TechDraw section.
I have a lot of notes and insights about different workbenches, but I do not have time to formally describe all this. If you can provide such comments in an informal way (but with examples and, for example, documents with films), I will do it willingly. My previous remark is that for a long time it has been a "Hole" function, but it does not correspond to the possibility of just dimensioning. I also miss the choice of a thread, eg M4 was also possible as a parameter from a spreadsheet. At the moment, this is not ...
Thank you from France ! do you know why the tolerances are not available in the data ?I can't see the 2 lines over and under tolerances...A macro is necessary ?
If you submit a feature request to the FreeCAD dev, in form of a thread of the forum, it's either 1/ this is not how freecad works 2/ then do it yourself and submit a patch or something in between those. This is why I stopped reading the forum
Give me a break. I've personally implemented features that were requested on the forum and I've approved features submitted by people who were encouraged to write them. I myself was encouraged by the early developers to work on Path despite my lack of experience. When you see push-back on the forum, it's almost always against uninformed users who nevertheless display an attitude of entitlement. I'll work with literally anyone if they come in good faith. But I hate it when users who cannot or will not code tell me that what I've written is shit. And I don't feel the need to be polite to such users.
Is it possible to use other symbols needed in manufacturing drowing? for example: true position tolerance or surface roughness etc. I saw it in drawing dimmensioning wb, but techdraw looks more professional.
You can use any symbols in svg form but it's still largely manual. There's some discussion in the devloper channel about adding more standard symbols for welding and other operations but there's many MANY standards worldwide and supporting them all is a challenge. Right now, I think only diameter and maybe a couple others are automatically added.

Another very nice video! Thank you! Keep doing this great work!
Thanks. Your lessons are clear and useful
Thank you for the informative video. I take it this only works on single parts, and not on assemblies??
Thanks for a clear and concise tutorial. How about the display of the measurement itself: it's not obvious to me how to alter the places of decimal applied to a dimension?
how to make a dimension line 13 mm from the model, and the size is 2 m from the dimension line? where to configure it?

I'm not sure. That's a question better asked on the forum where there are more techdraw experts
Thank you, as always very useful! Next time can you show us how to create a section view?
It won't be in the next video which is about multiview projections but part 4 is about sections and detail views
@@sliptonic Thank you very much 😃
How do you pull Sketcher constraints into TechDraw as dimensions?
I think these are 2 different thing, so not sure it is possible at all.
Also i think it is very different how you give dimmensions in 3d designing ang in manufacturing. In desing 10 mm is 10 mm. in manufacturing 10 mm is somewhere between 10.001 and 9.995 depend on your tolerance.

tolerances are a new feature in 0.18 which hasn't been released yet (very close)
