When ever we create a flat pattern of a .psm it generates the bend line on the dwg/dxf. But it generates bend/fold lines the whole length of the part. Is there a way to shorten these lines by default?We have to open the dwg aftewards to trim them.
Solved! Go to Solution.
the bend lines have a different line style, and are located on a separate layer.
Is this diffence enough for selected the appropriate geometry?
I never had any problem with the bend lines as the were since the beginning.
Do You create the flat pattern DXF from 3D model or form draft?
Bend lines should extend to the exyents of the material at the bend location. Are you saying that your DXF files are showing them longer than the material extent? Perhaps a picture might help.
By default they do extend the whole lentgh of the part, but that also means that the laser will engrave the whole line, wich will cost more $. That's why we want the fold lines to be just 2 small marks at each end of the folds line about 1" in length.
Bending information is typically used for just that....for etching, for which there is a seperate function, and unfortunately for you, additional work to add it to the model. We currently add this, when required, to the flat pattern of the PSM model.
Sort of like how "Index Lines" work, when making lofted flanges. That would be a useful additional option to have for "selected" bends....as they get translated to the DXF output.
I have had this called for also, but it can't be done on all parts, say, that have bends UP & DOWN, and also have one face mirror finished....laser etching would damage the face.

Got it. $0.25/inch seems expensive for etching with a laser...
Definetly get a change requests in for this via GTAC or your VAR. Also, any chance you are going to Solid Edge University? Sheet metal round table meeting is calling your name
The cost is a mixture of power consumed, life of the machine, support of operator time, etc. and a built in factor for scrapped parts. Even with all that, seams a bit high.
My guess is that's the cost to cut the thickest part. A cut and etch are priced the same.
My place is still using a punch and plazma. Eventually we will get a laser. One of the reasons I have to make bend tables for every part that include back gage. No effective way to mark the bend lines without creating a potential cracking problem for sealing sheet metal tanks.
Unfortunately, I don't know direct solution, but there is workaround. You have to define a "unique line style" in your drawing template. After this you can change line style for this special.
