Hi everyone

I'me having a problem while exporting custom imported fill patterns to dwg.

They show all messed up (see pictures), and this is happening with several fill patterns i've created importing from .pat files, incluind the "gravel" hatch that comes up with acad.

I'me using revit 2014 and acad 2014. I've tried also exporting from a clean file (with only the roof in the pictures) and it happens the same way.

The only workround is to export in milimeters (our dwg standart is meters). Then they show allmost ok, but not perfect. But that involved post-editing all dwgs, everytime we review the project, and that's allmost impossible,

Any ideas what is happening and how to fix it?thanks in advance

Take the PAT file and load it directly into CAD and see what happens.  If it works correctly then you can probably write a script to load it into your exported files.  If it doesn't, then it is a badly created file.  I have seen some of those from hatch conversion programs.

Hi WWHub, and thanks for the reply

I've tried what you suggested, but the thing is revit creates a dwg unique custom hatch in every face where the fill pattern is visieble. So for example a roof can have as much as 10 custom hatches, each one with an unique name and not refering to any *.pat file in particulry

I agree this can be a problem that originated in the program that produced the *.pat file i've imported to revit, since when I export in milimeters the dwg looks almost fine. So I think this can be an unit conversion mess up, somewhere along the way, or a question of producing the pat file in meters?

I've also tried editing in notepad, the units in some *.pat files but revit says afterwards the fill is to big.

And I've also tryied recovering the deleted pat files, revit produces temporaly when exporting to dwg, but when opening them in notepad, one doesnt see a normal "pat programing language".

I've searched revitcity for other roof tile file patterns and thay all produce the same thing, so I ask: Anyone out there has a spanish roof tile pattern that comes out ok in dwg (meters units)?

thanks

hi

you can try this link for semi-free PAT files:

"You could obtain points on free form by swapping files. To do this you can send us your CAD files, to make us able to value it."
