Re: Notes about Coordinate systems
yeah I don't see anything wrong there, although I personally would say "Point * is at * mm along the X axis of *"

Re: Notes about Coordinate systems
So this is the update version of my notes:
COORDINATE SYSTEMS AT Fcad V 0.3 2022-07-02
The objects at space are positioned using Coordinate systems. The most used system is the Cartesian.
In that system the three axis are perpendicular to each other.
The most "general" Cartesian Coordinate system in FC is the global axis system. It is a system with invariable axis and the less used by simple users.
We can view the Global axis system using the command Std AxisCross.
Most FC objects comprise their own axis system. It is very important to know every moment when with FC, to which axis system we are referred. If not, error messages will appear and the outcome will be a mess.
The following objects have their own axis system: Body, Std Part, Sketch , Shapes
The following objects DO NOT have their own axis system: Document, Group,
We can view the (Local) Coordinate system of the objects contained in the Body: Tree view ->Body->Origin and hitting Space.
Sketches have their own Coordinate system too which is …….. of the Body in which they are contained.
Shapes contained in a Body have their own Coordinate system which is … of the Body in which they are contained.
For the objects inside the Body we can create an Auxiliary Local Coordinate system using the command: PartDesign CoordinateSystem.
If we want to combine more bodies to make an Assembly we can use a Std Part. A Std Part provides its own (Local) Coordinate System.
Bodies inside a Std Part keep their own coordinate System.

Re: Notes about Coordinate systems
A ".doc" file is painful : try PDF or TXT or just quote it in your post.
Re: Notes about Coordinate systems
I used .doc in order to let other people make changes directly to the file . But it did not work that way: All corrections have been made at the posts.Shalmeneser wrote: ↑Sat Jul 02, 2022 11:24 am A ".doc" file is painful : try PDF or TXT or just quote it in your post.
So you are right .txt is enough even though it does'nt has the capabilities of .doc.
But please explain :.doc is used by Windows and Linux users , isn't a kind of de facto standard ?

Re: Notes about Coordinate systems
* ".doc" is not a standard, even for M**soft .
* It's not an open file format

Re: Notes about Coordinate systems
So what is the open file format which is used by Windows and Linux users ?Shalmeneser wrote: ↑Sat Jul 02, 2022 12:18 pm * ".doc" is not a standard, even for M**soft .

Re: Notes about Coordinate systems
For Windows users DOCX format would be vastly more common than ODT format.
DOCX is "owned" by MS, but it is openly documented, unlike the DOC format.
I do not believe there is any advanced format that is standard and commonly used across all platforms. Limited capability formats such as TXT and PDF are used, of course, but these have either limited capability or limited editability.

Isn't ODF based on XML?GeneFC wrote: ↑Sat Jul 02, 2022 3:02 pmFor Windows users DOCX format would be vastly more common than ODT format.
