Re: Save Copy as .DXF create a file that is almost 50x larger than .IDW

You should really try the method I described earlier. All of those manual steps you're taking can be set as options in the export utility.

Thanks, Mike.  I'll have to give it a spin.

 

(Note that once selected, the DXF output options will persist for the next Save-As.)

Sean,

 

The behavior you describe here does not seem normal to me. Could you send these Inventor files to me (johnson.shiue@autodesk.com)? I would like to take a closer look and see where the problem is.

Thanks!

Hey Mike,

 

I guess I should explain some of my processes and maybe it will make things a little clearer, not all of our parts are sheet metal pieces. Some are items that are cut out of thick steel to certain shapes and etc,with holes and slots whatever.sometimes requires machines or other machining practices.

 

So my typical process is

  1. Model the part
  2. detail the part on an.idw
  3. save .idw as .pdf and export as .dxf as exact copies of the final drawing.(including title block)

We send the pdf and dxf to the fabricator and they send us back the part.

 

So as far as creating .dxf, it is (was) something like 2 extra clicks, no extra work, no converting to sheet metal, no creating flat pattern, just simply save copy as dxf. Done, worked for months,never had an issue with file size or needed to find another way to export.

 

Up until i installed inventor on new computer and added in my templates with the updated styles, i never had an issue, there is something wrong my templates and it is adding some extra layers or something and making my dxf files 30mb's in size. as seen in post 7 of this thread.

 

I want my .dxf to be an exact replica of .idw, so right clicking in the model browser and exporting flat pattern to dxf is not really making anything easier(or harder),

 

i just want my inventor back to the way it was on the old computer.

 

Thanks for you help and info...

This happens with every part I draw up. If I send you my template file can that be used to help figure out the problem? Or perhaps some screen shots of some specific settings. As I mentioned in post 7, in made a test part...I then drew it up in my company template file and then drew it up in the inventor default idw file, saved, then exported a dxf from each idw and the one file was over 30mb and the one from the inventor default idw was less than 1 mb...

try saving a copy of your drawing, then deleting the border and title block one at a time from the copy, then save as a DWF and see what it does to your file size. Might help narrow down the problem.

Sean,

 

Many thanks for sending me the files! I took a look and found out it seems to have something to do with image in the title block. It seems like if the image is embedded (not linked) to the IDW file, exporting it to DXF will balloon the file size. If it is linked, the behavior does not happen. I don't have a good explaining at this moment. I need to follow up with development.

Thanks!

I see, Sean. I didn't realize you were trying to export a complete drawing; I thought you were just looking for the blank profile for programming. Something like what the other poster described as his workflow.

It looks like you have AutoDesk's attention with this so, good luck!

I re-embeded our logo image as smaller size and this shrunk the .dxf export considerably, I completely forgot that I updated our logo for that drawing template. I opened it in paint and resized it to from 2.2mb to 800kb and now my dxf exports are under 2mb, instead of over 30mb I will scale down the image some more and that .dxf will be back to normal around 500kb /page

 

Thanks to all for there input and solutions!

If the objest that is imported either grows or shrinks, use the scale command. Find out what the dimension is and what it should be. Determine the ratio between the two. (ei. dim. should be 3, is 82. : 3/82 = .0365 ) Next, enter the sketch and highlight the entire sketch. Then go to the "Scale" command. Select a base point, usually the origin. Enter the ratio. Should shrink the entire sketch equally and to the right size. Hope this helps.
