Editing and Nesting DXF files

Hi,

 

I am a new user of Autodesk LT.  I have installed it on a MAC.   I have digitized the panels of a Flying Dutchman sail.   The cut and seam lines of the panels are in DXF format.   I need to encode the lines in two different colors to send the digitized pattern to an Autometrix plotting/cutting machine.    A red color indicates a cut.   A green color indicates a draw.   There are about 25 panels that comprise the sail.  Once all the panels are properly encoded by color, I need to nest the panels onto a 36 inch roll of sail cloth.    The widest panel is 36 inches wide and uses a straight edge of the sail cloth.  The longest panel is about 3.5 meters.   I see to how to change the color properties of individual panels, but it is somewhat awkward to select seam and cut lines if they are close together.  Everything has to be one layer.   I do not know how to nest all the panels onto a 36 inch roll.   I would like to manually nest the panels to make sure straight edges are lined up properly on the roll of sail cloth.  Any help would be greatly appreciated. 

 

Thank you, Doug.

I'm not sure we can necessarily help you with your problem. It sounds like the bulk of your problem is solving the jigsaw puzzle you have created.

 

Some command you might find helpful:

GROUP: allows you to temporarily create groups of objects

SELECTSIMILAR: Sort of self explanatory, but it allows you to select similar objects and if you set the setting you can select by color.

JOIN: allows you to join lines together into a poly line.

ROTATE

MOVE

MIRROR: (unless there are obvious 'sides' to the cloth)

 

The way I would approach this is by laying out a 36 in tall rectangle on the drawing and place everything inside it then delete that rectangle after.

Good luck and let us know if you get stuck along the way.

Also it should be noted that AutoCAD for MAC is significantly different than what is available to the PC so you might want to check out the MAC forum if you have technical difficulties

You must use ALIGN (somehting like that) and its ability to work in 2D (4 points) with a scale option to be mastered with "no" !

and ROTATE but ROTATE with the Reference Option.

 

Do you know how to manage objects snapping (F3) ?

You need to put them on/off quite often and force them with SHIFT or CMD + ricght-clic at some right times.

You can also use the grid and its own snapping system (F7 and F9) ?

 

Good luck !
