Solved: DXF tiling

Do you have a question you want to ask an existing QCAD user about QCAD and what you can do with it? Do you want to know if a particular feature exists? This is the place to ask.

Solved: DXF tiling

Post by chrispedersen » Mon Jun 07, 2021 5:12 pm

I suspect a manual dive would answer this question.

Suppose I have a dxf thats 14' x 7 feet. My cutting table is 12 x 8.

I think the current version of QCad can tile a drawing, to a printer. But I didn't see a way to tile a dxf. Can it also tile a DXF; automatically?

Follow-up questions:
a). If I tile a drawing to the printer, can it be printed to an eps file? Could I then convert the eps to dxf?
b). Predominantly, I"m interested in trimming in the table feed direction (only). How difficult would it be to run a function that would split a dxf into two portions. In the above example, two 7x7 ft sections. I would want to insert a (dashed?) line as the sectioning entity.

Thank you!

What kind of drawing is that? Why is the format 14' by 7'?

To my knowledge there is not such an automatic function in QCAD. And honestly I don't see why it should have a dxf tile function. Depending on the drawing it should be easy to stay in a limited area of 12' by 8' or to tile it manually to that size. But without more details it is just a wild guessing around the possibility's ... :wink:

You could use the Modify > Clip to Rectangle tool to clip your drawing to the size of a tile and repeat for all tiles:
https://qcad.org/doc/qcad/latest/refere ... oRectangle

I wouldn't recommend to go the printing / PDF / EPS route as these outputs are really optimized for printing not further processing.

So my apologies for asking a lot of presumably simple questions, and using nomenclature that probably isn't what you're accustomed to.

My customer uses cardboard templates as stencils to cut fabric. So if he needs a stencil that is 14x7 - its too long for my table, but there is no problem using two pieces 7x7, (or 6x7 and 8x7, or ...)

So I am wondering if there is an automatic way to split a dxf file that is too long into multiple pieces, much like is accomplished for printing by your tiling algorythmn

Again, Modify > Clip to Rectangle is pretty much that. You'd draw a rectangle around your tile and QCAD splits all entities at the tile edge. You can then move the two parts to separate drawings, etc. as desired.

This could be one way to accomplish that task with the suggested tool by Andrew:

You guys are brilliant and helpful. I'm changing the topic to solved. Next thing is for me to try some scripting!
