convert text entities to lines and arcs

[Sergi]

Hello,

Is there a way to convert text entities to lines and arcs ?

Best regards.

Hello.
The task is not trivial. What is the purpose of such conversion? Have you considered using SHX fonts?

Hello Alexander,

I need a way to extract vertices from CADText entities.

I've been working with hgpl and cgm export without good results.

SHX font could help me to achive my goal ?

Hello Sergi.
SHX font contains a set of polylines for texts visualization. The following code must be used before importing a drawing to allow using SHX fonts:

Code: Select all

CADImage cadImage;
...
cadImage.Converter.SHXSettings.UseSHXFonts = true;
cadImage.Converter.SHXSettings.SearchSHXPaths = true;
cadImage.Converter.SHXSettings.SHXSearchPaths = @"c:\Program Files\Autodesk\DWG TrueView 2011\Fonts;c:\Users\Support.CST\AppData\Roaming\Autodesk\DWG TrueView 2011\R8\enu\Support"; 

SHXSearchPaths must contain the path(s) to required SHX files. The following example shows how to add SHX text to a drawing:

Code: Select all

CADText entText = new CADText();

CADStyle txtStyle = new CADStyle();
txtStyle.Name = "my_style";
txtStyle.PrimaryFont = @"c:\Program Files\Autodesk\DWG TrueView 2011\Fonts\txt.shx";
cadImage.Converter.Styles.Add(txtStyle);
cadImage.Converter.Loads(txtStyle);

entText.Style = (CADStyle)cadImage.Converter.Styles[cadImage.Converter.Styles.Count - 1];
entText.Color = Color.Red;
entText.Point = new DPoint(0, 0, 0);
entText.Height = 10;
entText.Rotation = 0;
entText.Text = "Hello World!!!";
entText.Loaded(cadImage.Converter);
cadImage.Converter.OnCreate(entText);
cadImage.CurrentLayout.AddEntity(entText);

Hello Alexander,

but how can I get the PolyPoints of the CADText entity ?

Sergi

Hello Sergi.
DXF specification doesn't provide any polypoints for texts. Have you tried export shx texts to hpgl or cgm? What's the problem with export?

Alexander.

[Sergi]

Hello Alexander,

I've tried export to hpgl (bad resolution for arcs and splines) and cgm (better than hpgl, but not good, and moreover resizes the original).

You answered me an email telling that CADtoHPGL.Settings.XScale works incorrectly in current software version and you are working for fixing the problem.

Do you know when it will be solved ?

Sergi.

[support]

Hello Sergi.
The resolution term doesn't applicable to vector formats. HPGL sizes defined by its commands. CAD Import .NET current version exports to HPGL with default scale 1 drawing unit = 1 HPGL millimeter. CADtoHPGL.Settings.XScale will be fixed expected at close time.
What about SHX fonts, have you received required effect?

Alexander.

[Sergi]

Hello Alexander,

- The resolution is not 1 unit -> 1 mm HPGL. Long arc entities have only a few points.


- If I increase text height the resulting HPGL file is the same ! More units not give me more points.


- I've tried SHX fonts with no new effect.


- On Mainform()

cadImage.Converter.SHXSettings.UseSHXFonts = true;
cadImage.Converter.SHXSettings.SearchSHXPaths = true;
cadImage.Converter.SHXSettings.SHXSearchPaths = @"c:\Fonts"; //shx fonts directory


- On create text entity

CADText entText = new CADText();

CADStyle txtStyle = new CADStyle();
txtStyle.Name = "my_style";
txtStyle.PrimaryFont = @"c:\Fonts\extfont.shx";
cadImage.Converter.Styles.Add(txtStyle);
cadImage.Converter.Loads(txtStyle);

//entText.Style = (CADStyle)cadImage.Converter.Styles[cadImage.Converter.Styles.Count - 1];

entText.Style = txtStyle;
entText.Color = Color.Red;
entText.Point = new DPoint(0, 0, 0);
entText.Height = mm_alt;
entText.Rotation = 0;
entText.Text = text;
entText.Loaded(cadImage.Converter);
cadImage.Converter.OnCreate(entText);
cadImage.CurrentLayout.AddEntity(entText);

- If I import the resulting hpgl file the entity is not the same as the original (not complete, broken ...)

- The resulting hpgl file duplicate points (example with cadtext entity representing number 1)

Hello Sergi.
Please specify if you create the drawing from start or import it. Please send to support@cadsofttools.com an imported drawing, if any. Otherwise please send a demo with one or two entities creation and export, as it proceeded in your application.

Alexander.

Hello,

As this might be an old thread, is there any update or a new feature to help converting text entity into a polyline? whether the text is imported from DXF or created using CADEditorX editor.

Best.

Unfortunately, there is no function for converting a TEXT entity into polylines.
