Summary0003818: PartDesign Hole Depth Dimension should provide the option not to take the angled drill point type into account
DescriptionIn the PartDesign Hole feature, the Depth Dimension option controls the overall depth of a blind hole. When the Drill point option is set to Angled, the dimension includes the conical end point generated by the Angled drill point option.

There should be an option to set the depth dimension so that it does not include the conical end point, to comply with some standards.

@LAROBERTE Did you mean Path Workbench ?
Have you opened a forum thread to discuss this ? (per our guidelines at the top of the page)

Hello
I do not speak English, it is very difficult for me to open and follow a discussion, I am obliged to translate everything, it is long and tedious.
I looked in the forum if someone was talking about it, but I did not find anything.
The problem is not a bug, but rather an error in the standards of rating, surely very easy to solve, that's why I intervened.

I have never seen this dialog before - where does it come from?

Ok
I take care of it, but I do not work until Tuesday
thank you for considering my post.

Bug was wrongly reported in "FreeCAD (all projects)" instead of PartDesign.

Changed bug severity from major to minor.

I cannot reproduce the issue. For me, if I set the hole depth to 10mm with angled drill point, the 10mm value includes the drill point. Please provide your FreeCAD info as explained in the enormous yellow banner that you could not possibly miss.

I'm switching this report's status to feedback required.

Okay, I think I understand the issue now. You actually want the hole depth NOT TO take the conical end into account.

This would be a feature request then, because in commercial software I use, both possibilities are offered (depth with or without the conical drill point).

hello, the downhole cone should never be included in the hole depth, it is only the consequence of the shape of the drill bit. The depth of a hole should take into account only the part with the correct diameter. see the two links of my first post.
if you want to add a feature, you should be able to choose the thread depth and drilling depth. Drilling and always deeper than the threading so as not to break the tools. the angle of the drilling cone is 120 degrees, the angle of the thread is 90 degrees. I do not have freecad until Tuesday, I promise you to make a correct post as soon as possible.
it's not very important for 3D printing, but it's very important for mechanical machining

LAROBERTE
I disagree. At work, plenty of time I really, really needed to define the total depth of a blind hole including the drill tip, so it would not punch through the material or would leave minimal thickness. Doing it your way would require guesswork or calculation.

As I said, Solid Edge (a commercial mid-range CAD package) offers both options. FreeCAD should do the same.

Your other arguments about thread depth and drilling depth are of course to the point. But the Hole feature cannot currently display a modelled thread, and the TechDraw workbench cannot extract hole information nor display it; so implementing this at this time would not really be useful. With 0.18 nearing release I doubt that we will see this implemented before release, which is why I set the target version to 0.19. Unfortunately, there is no longer a developer dedicated to the PartDesign workbench.

I agree with you, which is why my first post did not mention a request to add a function. I know that Freecad is evolving, but in the current state of things, the most important is the useful depth of the hole, which is the current standard in technical drawing. if you feel that the cone depth is half a diameter, you will have no problem and it is very easy with a 3D software to see if the cone of the bottom of the hole passes through.
Of course, if the drill cone is a problem, nothing prevents you from making a hole with a flat bottom with a suitable tool.
very cordially

Hello
For years, technicians have been working to develop international standards for technical drawing.
If you want freecad to become one of the software that can also be used by professionals, you have to respect them.
The Hole function of freecad is for the moment only the draft, I am sure, of a practical and complete intuitive function. You can add as many functions as you want, but basic functions and their default values ​​must comply with existing standards.
I am willing to participate on a forum to help develop Freecad, this particular function, but I opened this post only to correct this glaring error which will only cause the development of other functions or options for the materialization of the threads of freecad.
I'm not sure if the translation is understandable, I'm really sorry I do not write English directly.
I leave attached sketches that will be more meaningful than me.
Very sincerely
