removing chains and entities
« on: October 23, 2009, 10:38:00 AM »
Ok here I go again.
Am bringing in my image oops DXF into Lcam.
Looks good have double lines etc.
Have removed a lot of the lines and speckles with rem objects.
very time consuming.
I also want to remove some of the entities in a chain
example #664 to #702 in chain 24
To do one entity at a time will take quite awhile.

Is there a way to select multiple objects first or multiple entities then remove?

you can do a few things that help. but it is still time comsuming. play with these functions,zoom,select in box,chain ent sel,single multiple.
here is a tip, when i do something like what you want to do. get some tracing paper and a fine point black sharpie. trace what you think should
need to be a chain. scan your tracing as a tiff file, then convert it. makes chain cleaning a lot easier.

HMM.....
Why not be a bit more logical in what you want to do before you import the DXF. All in the manual.
Saves time and you know what is what.

Hmmm thought that editing the image before saving as a DXF would be the case.

So properly would be to take more time to clean the image in photoshop first.
Open it in Inkscape to change to DXF then to Lcam for the code and then to Mach

Hmmm...."properly" is maybe a bad word.
Any raster ( image file ) to  vector conversion ususaly gives a bunch of "stuff" that you have  to clean up
to suite yourself. What i was meaning by "proper" is that once you have what you want to machine , stop and think in terms of the "machining" that will be done to the piece before it is DXF'd.  But again, that's was my personal
preference on using LC, and still is, when i wrote the manual. You may want to add extra lines, clamps, an offset, or whatever and named appropriately to make using LC easy or not have to use some of the tools that are available in LC.
