Not delete .PAT definitions DWG exports

[hanslammerts]

Hi,

I noticed many times that Revit will make .pat definitions while creating DWG exports. When the proces is done, these definitions will be deleted. I think it would be a good idea to let the user decide where to store these definitions and if these should be kept? This would same time using 'GETPAT' routines later when AutoCAD (verticals) are involved.

Hi @hanslammerts

If this is for some other type of specific request that doesn't exist today with the product, you may submit your request through our IdeaStation.

The product team will review this request and take it into consideration for further development.

Also, see Revit: Creating and duplicating fill patterns

We can create simple patterns from

1. Click Manage tabSettings panelAdditional Settings drop-down Fill Patterns.
2. Default fill patterns are stored in the revit.pat and Revit metric.pat files in the following location:%ProgramFiles%\Autodesk\Revit LT 2015\Data. 

Please select the Accept as Solution button if my post solves your issue or answers your question.

What difference is there between AutoCAD and Revit using *.pat

Could they (.. purely theoretical..) work with the same PAT file definitions? why can't they?

[Sahay_R]

They actually do. You can bring in fills to Revit from the PAT file that AutoCAD uses.

[hanslammerts]

So, if the R and the A can draw thing with the same definitions, why do users would need to tweak thing to do that?

[Sahay_R]

No tweak required. When you set up a new custom fill, instead of navigating to the Revit PAT navigate to the ACAD PAT.

I was talking about the exporting of (AutoCAD) DWG from Revit, not using PAT in Revit!

It is difficult to understand why all hatches in the DWG come out as custom with a missing definition (unrecognizable)

When the methods are there to make a good translation between these two programms.

1. Revit makes custom .pat definitions (why?)

2. Deletes the made .pat files from the DWG folder them after they are made (KEEP THEM!)

3. AutoCAD notices that the defintions are not available

4. but all this can be avoided  because both programms work with .pat files

5. I'm missing the logic here.

Check with your system admin see if they can setup a folder that you can write to but cannot delete from.  Then export DWG from Revit to that folder.

[hanslammerts]

System admin probably knows little Revit,  let alone working WITH AutoCAD.

Questions remain

That is not related to Revit or AutoCAD, but users' read/write/delete rights.

Explain yourself. I don't follow

[ToanDN]

It is clear as it can be.  If you don't understand then just write down what I said and show it to your server/system administrator.

What Revit wants, explains and has some wierd sollution

I made the sections Bold

http://wrw.is/tag/pat/

You may have noticed that when you export a DWG file, Revit temporarily creates PAT files in the export folder, and then it deletes them, just leaving DWG and PCP files.

To RECOVER THE DELETED PAT files, you can simply use the program Recuva!

I’m not sure how well this works for network shares or NAS devices, but it should definitely work if you export the DWG to a local drive and immediately recover the PAT files (before doing anything else).

[hanslammerts]

Get the picture? @ToanDN

[ToanDN]

What picture?  Recovering the deleted files?  Yes I got it.  Thanks for sharing!

[hanslammerts]

Then you probably understand that it has nothing to do with read/write permission.

But it's a ridiculous 'sollution' to get the pat files.

They should have made the dwg export setting pat tab a 'default' indication in stead of 'custom'

it's clumsy programmed with any understanding of dwg.

I don't think you understand my initial suggestion.  If you have folder you can write to, but CANNOT delete from, then the PAT files cannot be deleted by the program after they were generated.  What I suggested has absolutely everything to do with folder permissions.

[hanslammerts]

Most absurd workaround i ever heard..

[ToanDN]

"Extreme situations require extreme measures" 

But judging by your tone you likely have never heard of it either.

[hanslammerts]

Working with .pat files is not what i would call a 'extreme measure. It' oldskool, back to the 80's

not sure autodesk software can provide any support this kind of low tech anymore, guess not.

wishfull thinking.  but it is ok to disagree about what is ' a normal sollution'  friend
