Macro FCInfo

Gives a series of informations about the selected shape and can display a conversion of length, inclination (degrees, radians, grades, pourcent) shape, surface, volume and the weight of the form in the density selected in different units of quantities international and Anglo-Saxon.

Utilisation

Select an object or launch the application and select an object, and a series of informations appear. His calculations based on unity of FreeCAD, which is the mm to each new selection, the length unit always comes back on mm and angle on decimal degrees.

Sector 1: Document

• Document name
• Label of the object
• Internal Name of the object
• Sub element name of the object
• Type of the object

Sector 2: Coordinates click mouse

• Coordinates X,Y and Z click to mouse
• The button create on point, axis, plane, copy vector axis form FreeCAD.Vector(-24.0, 240.0, 7.0)

Sector 3: Value

• Vertexes and details of the shape (compt_Edge), (compt_Faces), (compt_Vector of the Face)
  max 200 lines in the table, if there are more than 200 lines it appears (!+ 200) and the number of lines
  (full details can save be the Save button in a file in CSV format and can be viewed the file in spreadsheet with the Read or by an external spreadsheet as LibreOffice OpenOffice or other)

Sector 5: Inclination

• Inclinations of the object can be displayed in:
• decimal degree, ex: 174.831872611°

  • Line this button create a line in direction of the object
• ValueAt, returns the 3D vector corresponding to a parameter value.

Sector 6: Surface and Volume

• Surface of the form displayed unit size can be selected
• Surface of the face displayed unit size can be selected
• Volume of the form displayed unit size can be selected
• density of the material in kg by dm3
  (the "spinBox" is set to 7,5 kg, average density of steel. If you want a different default value, change the value of the density, line 204)
• The gram buttom unit mass can be chosen :
  ton,quintal, kg, hg, dag, gram, dg, cg, mg, µg, ng, pg, fg, gr (grain), dr (drachm), oz (once), oz t (once troy),
  lb t (livre troy), lb (livre av), st (stone), qtr (quarter), cwt (hundredweight), tonneau fr, ct
• weight of the form displayed unit mass can be selected

Sector 7: BoundBox

• BoundBox extreme dimensions of the shape

Sector 8: Center of:

• Center of the shape and these coordinates XYZ
• Center of mass and these coordinates XYZ
• The button create on point, axis, plane, copy vector axis form FreeCAD.Vector(-24.0, 240.0, 7.0)

Sector 9: Inertia

• Moment of inertia and these coordinates length and weigth
• The button create on point, axis, plane, copy vector axis form FreeCAD.Vector(-24.0, 240.0, 7.0)
  • action line 1 : x1, y1, z1
  • action line 2 : x2, y2, z2
  • action line 3 : x3, y3, z3
  • action 4 diagonal : x1, y2, z3

same for length and weigth

• Determinant 1  : computes the determinant of the matrix scientific value
• Determinant 2  : computes the determinant of the matrix decimal value

Section 10: SpreadSheet

• Read : read the data in a spreadsheet saved .FCInfo or txt, asc, csv
• Save : save the data in disk in the form selected below .FCInfo or txt, asc, csv
• Tabulation : the separator is Tabulation
• Comma : the separator is Comma
• Semicolon : the separator is Semicolon
• Space : the separator is Space

Option for save or read the spreadSheet with different separator, Tabulation, Comma, Semicolon, Space
The Tabulation are the separator for the FreeCAD spreadSheet module
The number of this four separator are calculate for help if unknown
The COMMA are the old (01.16 and before) separator of the FCInfo macro
Now for compatibility with the FreeCAD spreadSheet and since 01.17 version the TABULATION is the separator by default
If you want to convert your old FCInfo spreadsheet : Open it in FCInfo and save it with the Tabulation option checked

Section 11: Main

• CheckBox Clip Board  : if checked the coordinates are saved in clipBoard form : FreeCAD.Vector(-24.0, 240.0, 7.0)
• CheckBox Point  : if checked one point is created in the coordinate displayed form : FreeCAD.Vector(-24.0, 240.0, 7.0)
• CheckBox Axis  : if checked one axis is created in the coordinate displayed form : FreeCAD.Vector(-24.0, 240.0, 7.0)
• CheckBox Plane  : if checked one axis plane is created in the coordinate displayed form : FreeCAD.Vector(-24.0, 240.0, 7.0)
• Ref  : Refresh the display of data in report view
• Exit : Exit the macro (you must restart from the tool bar button or menu "View > Panels > FCInfo"
• CheckBox 1  : If this CheckBox is checked the informations are displayed in the report view window
• CheckBox 2  : If this CheckBox is not checked the window macro are displayed to right (default). If it is checked the window macro are displayed to left

Once launched macro, the macro remains active and the window remains visible. To exit the macro by pressing Exit. If you leave by the cross, the macro remains in memory and the data appears in the "report view" of FreeCAD.

Options

The unit used

Length unit:

km, hm, dam, m, dm, cm, mm, µm, nm, pm, fm, inch, link, foot, yard, perch, chain, furlong, mile, league, nautique.

Angle degrees :

1. decimal degree, ex: 174.831872611°
2. degree minute seconde, ex: 174° 49' 54.741401''
3. radian, ex: 3.05139181449 rad
4. grade, ex: 194.257636235 gon
5. pourcent ex: 30° = 57.74%

Understanding of angles in FCInfo display.

Weight unit :

ton, quintal, kg, hg, dag, gram, dg, cg, mg, µg, ng, pg, fg, gr (grain), dr (drachm), oz (once), oz t (once troy),
lb t (livre troy), lb (livre av), st (stone), qtr (quarter), cwt (hundredweight), tonneau fr, ct

the "spinBox" is set to 7,5 kg, average density of steel. If you want a different default value, change the value of the density, line 206

global densite       ; densite       = 7.5  # (steel = 7.5 kg par dm3) 

A file can be created by the button Save. The file is written as a file csv in this way, the data can be studied in a spreadsheet in FreeCAD or Openoffice, LibreOffice...

Script

Copy the contents of the macro in a file named "FCInfo.FCMacro"

• Windows: the form is usually " drive:\Users\your_user_name\AppData\Roaming\FreeCAD\ "
• Ubuntu: the form is usually " /home/your_user_name/.FreeCAD ".
  

Or, directly in the interface of FreeCAD
The icon must be in the same directory as the macro.
Download image positioning on the icon and then drag the mouse right click "save as" (do not change the name)
PS: too long to be contained in the wiki page (for the time being the wiki pages accept only 64 KB) the macro code has been placed in the forum

global uniteSs       ; uniteSs       = u"mm²"
global uniteVs       ; uniteVs       = u"mm³"
global uniteAs       ; uniteAs       = u"°" 

global uniteSs       ; uniteSs       = "mm"+iso8859(unichr(178))
global uniteVs       ; uniteVs       = "mm"+iso8859(unichr(179))
global uniteAs       ; uniteAs       = iso8859(unichr(176)) 

Download the icon file Macro_FCInfo_Icon unzip and copy the icon in the same directory of the macro

Dwnload the macro file on gist docked to right

Download the code file

last version Macro_FCInfo and the icons at the end of the page

(Or On the forum. )

PS: this macro uses getSelection() and the list of object begin to 1 ex: for a box Edge1 to Edge12 and the code in the console start at 0 ex: for a box Edge[0] to Edge[11]
This is normal the counting on arrays/lists inside OpenCascade always starts at 1 and not at 0

Limitations

Always leave the button Exit. If one exits the program without going through the button Exit the program remains in memory and continues to run and the display will remain in the "view report". You must leave FreeCAD to erase it from memory.
Only the first 200 elements of the object are visible in the table if there are more than 200 items in the object a signal will be displayed by "'(! +200)" '. The complete list of data is visible in the file saved by the button Save.

If the window macro is invisible after the run , see the bottom window :

project:
read the file directly in a table. done
matches the "Edges" and their coordinates done
Association of a substance to its density
inclination on the element rather than the global object done
inlay right in the interface of FreeCAD done
