Draftsight C is to fill in once the DXF is done. But starting from a vectorization of the image, is there no way to fill with shapes like in Illustrator?
Of course you have to create your typical hatching the first time but then it rolls by itself.
I used corel before but that was before .... since illustrator -> draft I clean up and I enter everything in SW in sketch. From there by filling in my material and volume I have the hatching
The problem is that the image we have is in A4 format and there are thousands of small areas that need to be hatched so it's difficult to do it manually.
+1 @Aurelien because yes if the hatching doesn't represent the mantier, what are they for?
Then the A4 format doesn't matter because you can resize the image or the sketch in SW.
@gt22 your tutorial on the image that we resize to draw a sketch on it.
For the sake of confidentiality I propose a trial in PM. I'm working on a similar subject for another colleague from Lynkoa, because having the tools allows you to know the feasibility
for example a simple aluminum profile image recovered on A4 ech 12/1 sheet vectorize illustrator export DWG, clean DWG with draft and import in sw as a 2D sketch
the pulse duration is around 200femto second and the power is 20W.
This therefore has a very high peak power and allows us to machine a lot of materials. It is also possible to machine sapphire ... (well that's the R&D part that knows more)
In general, we do 20x20mm or 40x40mm machining
We also usually have a DXF at the beginning and our engraving software does the hatching. To do this we need to open the DXF in our software and we need to put a flag in the letters of a text (e.g. for example) that we want to engrave.
This is therefore an impossible thing to do with hundreds or even thousands of DXFs.
Moreover for the moment it is not possible to do this with a large DXF because our software transforms the DXF into a bitmap and if we take a 10mmx10mm image with a 2μm hatching it is a lot of data because (basically) we have an info every 2μm
so we're a bit stuck because we don't know how to manage large DXFs.
He is also capable of doing what is called "split field"
When you have a 50x50mm DXF (for example) you can divide it into 10x10mm areas and do a machining with overlap.
Either if the DXF is small enough, the software is able to do the cutting
Otherwise, if the client gives us cut DXFs, we can do the same thing by placing ourselves in the center of the 10mmx10mm area (to mark the first area) and then move 10 to 10 to mark the rest of the areas.
As additional information, we have an image in file. AI (black and white) that we know how to transform into dxf but they are completely different shapes.
In addition I tried to make an extrusion of the DXF but there are common points in some areas and the extrusion does not work for areas with a common point.
