IMPORT DXF AND NOT SHOWING BLOCKS

Hi Guys,

When I try to import in DXF files the dimensions are coming in as blocks and for some reason I cannot see these blocks.  When I click edit block it opens a separate window and the dimension is there.  Why can I not see the blocks in my main drawing ?

Hi ben83,

can you provide a testcase dxf?

 (Librecad 2.0.9-38-g57e7037 / Mac OS 10.10.3 Yosemite )

As ben83  I encounter a problem when importing a .DXF (correctly opened by (e.g.) e-drawing) :
all dimensions become so small they are unreadable, and figures are all converted to 00.000.

here attached, two files: the original DXF as opened and saved by e-drawing,
the coopy as opened and saved by librecad
two_dxf.zip

Hopefully our dimensions specialist Rallaz will resurface soon...

The conversion to 0.0000 is beyond me.

For the text size you can use Current Drawing Preferences -> Dimensions -> Text height

Thank you ravas
I tried your 'edit -> Current Drawing Preferences -> Dimensions -> Text height' 
suggestion, but nothing shows up.

Could it be that the layer where 'dimensions' are stored in my (ComputerVision made)
DXF files is invisible to Librecad?  (reminder, this layer is visible in SolidWorks e-drawings)

PS: where on this forum may I ask if there is a Librecad training curse in the Paris
or Grenoble area ?

For some reason that option uses a combobox with a max value of 5.
Try entering a much larger number.

dear ravas,  when doing this (scale 50) I get a huge 0.000 figure and when I trigger the autozoom, the drawing itself becomes so small it's almost invisible below the 0.000
That is very strange because my friends using Cad programs under windows perfectly open the dimensions
data carried in the very same file I am unable to correctly open with LibreCad for Mac.
(I am runing Yosemite)

Another strange thing: when selecting:   file ->export -> export as pdf
I get an empty 1K file

Try selecting a paper size in current drawing preferences,
and change the scale in print preview.

Thanks, this perfectly works, problem solved ;)
Now only remains to extract the lost dimensions from their 0.000 Kelvin deep space
(I hope Rallaz is not retained for too long in the same location).

Adobe Illustrator, DraftSight or eDrawings can open my DXF files
with their dimensions, but LibreCad opens them with almost invisible 00.000 figures only.

I changed "current drawing preferences -> dimensions", but as soon as I click the OK button,
without even changing any value, all the tiny imported 00.000 dimensions disappear.
Exiting with 'save', makes them not to appear again when reopening the saved file.

Mac Yosemite 10.10.5 / LibreCAD_2-1-0_alpha-02.

reading  your Feb 06 reply to springer :
 " With OS X 10.11.1 / Qt 5.5.1 and the latest LibreCAD code the dimensioning issue does not exist. ", should I install El Capitan in my Mac?  I was reluctant until now but if this solves my dimension import problem, I will do it !!!

ESCAL_origin.DXF

I tried your file.
I had to set General Scale and Length Factor to 1
and the text height to 5,
and then the dimension at (0,0) appeared.
However, it is 0.0000

Unfortunately there are no developers experienced enough or interested enough to solve this right now.

So, I am in dire staits with my Mac.

Can you give me two minutes of your time to open
this PersonalDesigner-made DXF file
with LibreCad / Windows ?

If it works I wil borrow a PC :)

Aside from the GUI style / rendering and some hotkeys, LibreCAD will function the same on both operating systems.

Do you mean that whatever the OS, Windows or Mac,
LibreCad can't import a foreign DXF drawing with its dimensions?
I know there is a myriad flavors of DXF on Earth but I still hope there is at least one
in the attached list which is compatible with LibreCad !!
Would you tell me which one ?
Merci !!

I can't say for sure, but I did find this in drw_base.h

namespace DRW {

//! Version numbers for the DXF Format.
enum Version {
    UNKNOWNV,     /*!< UNKNOWN VERSION. */
    AC1006,       /*!< R10. */
    AC1009,       /*!< R11 & R12. */
    AC1012,       /*!< R13. */
    AC1014,       /*!< R14. */
    AC1015,       /*!< ACAD 2000. */
    AC1018,       /*!< ACAD 2004. */
    AC1021,       /*!< ACAD 2007. */
    AC1024,       /*!< ACAD 2010. */
    AC1027        /*!< ACAD 2013. */
};

hello Feragon,
thank you for your offer, here is the proof: 1540036_import_librecad_00000_.zip

-1 original made by ComputerVision's PersonalDesigner
-2 as opened by LC : no arrows, numbers converted to miniature 00000
-3 perfectly opened by DraftSight
-4 yellow dimensions added by drafsight, saved as Ascii R2013
-5 drafsight added dimensions are correctly opened by LC,
    the PD original ones are now visible but still zeros and no arrows.

joli casse-tête ins't ?

It makes them more prominent, and potentially exposes them to more developers.

Done !
