Width and height of plt

[krez0n]

Can I get real width and height of plt or dwg file? AbsWidth and AbsHeight always return 1.0 (((

Hello,

AbsWidth and AbsHeight must return respective values if file is valid.
Could you please send us your files for testing to support@cadsofttools.com?

Sergey.

Please post questions to the forum or write to support@cadsofttools.com

Hello,

Which unit of measurement does AbsWidth and AbsHeight return?

[support]

AbsWidth and AbsHeight return CAD units. These values are being counted basing on entities' coordinates as they are in CAD file.

Thanks for the quick reply.

do you know if AbsHeight and AbsWidth will return millimeters when i set before the millimeters property (CADImage) to true? (sample code below)

CADImage cadImage = CADImage.CreateImageByExtension(path);
cadImage.Millimeters = true;
double width = cadImage.AbsWidth;
double height = cadImage.AbsHeight;

What will be stored in width and height vars?

Thanks in advance

I am interested in this thread as well. I am trying to figure out how to calculate my PLT dimensions in inches.

[support]

This property is obsolete. Line:

Code: Select all

cadImage.Millimeters = true;

gives nothing.

So, what's the way to get the real measurements in millimeters, centimeters... of the CAD file?

[support]

Can you please describe in detail what do you mean under "real measurements"? CAD file contains the whole data as CAD units, they are neither millimeters nor inches. cadImage.Millimeters defines whether CAD units to be interpreted as millimeters or inches.

First of all, Is there a correspondence between CAD units and inches or millimeters?

If that correspondence is not generic, I suppose that a particular CAD file should include the information of the picture real dimensions. I mean, a correspondence between cad units and real units (millimeters or inches). Does your library provide this information?

Suppose that you import a CAD file with information from a floor of a building, I must know the real dimensions of that building in 2D (length and width in millimeters or inches)

Dear Javi Gonzalez,

1 inch = 25.4 mm - this is a correspendence beetween these units.

Suppose that you import a CAD file with information from a floor of a building, I must know the real dimensions of that building in 2D (length and width in millimeters or inches)

We import data as it is. The question is how to interpret received data. Everything depends on what exactly this file contains.

Here is an example PLT file.

When I open this PLT in ABViewer and look at the File Info it tells me that Measurements : 1021x737 mm

How do I get this number in CADImport?

Thanks

Currently exact measurements for PLT files are unavailable in CAD Import .NET. We will inform you when the problem is solved.

Hello!

We recommend to use the following code:

Code: Select all

	double vHeight, vWidth;
	int FMMWidth, FMMHeight;
	vWidth = this.cadImage.PureExtents.right - this.cadImage.PureExtents.left;
	vHeight = this.cadImage.PureExtents.top - this.cadImage.PureExtents.bottom;

	FMMWidth = (int)(vWidth / 40);
	FMMHeight = (int)(vHeight / 40);

it gives result in millimeters.
