2d drawing of brep

[Mr. Bram1 Kerkhofs1 0]

Hi

 

I was busy with checking if I could make a technical drawing from a brep.

In attachment I put a shape, and I would like to make a drawing out of it.

 

I tried to experiment with the 2D window a bit, and also with the FGIGeometry's that you get, but for now I can only make a drawing from a line, not from a surface or a brep.

 

Anybody an idea?

 

Thanks

Hi Bram,

 

Yes you are right - the 2D-drawing functionality covers only curves, and sections (e.g. from a section group that are generated on surfaces and breps). For breps itself, we have not implemented it yet. This is a TODO on our list. 

 

Here is a possible solution:

 

Some users write their own feature definitions in CAESES to visualize 2D-data in the 3D-window - and then export it to have some sort of custom 2D-drawing. For breps, you can loop the edges (command: brep.getEdge(...)) and use "dimension lines" (menu > visualization > linear dimension) to set up a 2D drawing. This is a bit of manual work (typing the stuff in a feature) but on the other hand it allows you to customize it fully to your needs.

 

Sorry for not having a faster solution available at the moment,

Joerg

Hi Joerg

 

No problem,Thanks for the tip!

 

If I can make the drawing to scale, that would be already good :).

I put a working case in the attachment.

It basically gets all the lines from a brep and puts them in FGIGeometries and loads them into the screen.

 

Note: The input breps must be in between square brackets (as an objectlist)

 

Cheers

Hi Bram,

 

I took a look at your file - it seems to do what it is supposed to do so far... Would you need further guidance?
