I would like to extract/projection outline of nonsolid 3D object to 2D lines

[PowerP]

I wish to have outline/surface of those nonsolid 3D object convert or projection into 2D lines that can be use later.

 

For solid object, its can be projecting the surface by FLATSHOT command

But for nonsolid object, this command is doesn't work and showing nothing when I tried.

 

 

PS. These nonsolid object probably copy/export from other software ie. some analysis software.

 

Anybody can help me out?

Thanks a lot

Welcome to CADTutor.

 

You might want to try FLATTEN.

Hi Dadgad

 

Thank for your warm welcome and help

 

That FLATTEN command does work out but its as badly present coz its only showing in straight line not smooth at all

Flatten definitely has its uses and its problems.

Working with curved 3D lines is definitely going to be one of its problem areas.

I don't use it myself, as I always work with 3D solids, but I have seen

FLATSHOT take great liberties when representing curves of tangential faces.

Try increasing your FACETRES system variable from the default value of .5 to

5 and see if that might help you at all.

Try with this Macro added to a button.

 

Flatten All

 

^C^C_UCS;;_move _all;;0,0,1e99;;_move _all;;0,0,-1e99;;
_chprop;_all;;_thickness;0;;

 

Flatten a Selection

 

^C^C_UCS;;_select \_move _p;;0,0,1e99;;_move _p;;0,0,-1e99;;

 

 

I Wish Everything Were Flat article from Cadalyst if you want to try tracing.

Hi SLW210

 

could you please re-check your code again? as I have tried it but the out put does'n work that way I wanted. its came out as large area of individual spot.

 

thank a lot, mate.

I think you are expecting a lot for someone who's model was not a true 3D model to begin with.

Might help to actually post the .dwg here.
