I just Googled your question and found this one.
I made in 7.5 this tricks, upgraded to 8.5 and 9.0 by modifying same files.
I created the drawing template in NX. But I dont have rights to save the file in C: as well as update the pax file. How do I explicitly give the file location in the template file.
Again, how do I populate my custom template?
You need to have administrator permision on machine.
This works for any type of template. It is necessary to edit the correct paxfile. For Native NX, do NOT edit any of the pax files that start with"nxdm_". These files are specific to NX Manager. After creating the template file and placing it in the /ugii/templates folder,edit the ugs_drawing_templates.pax file in a text editor. Notice thePaletteEntry sections. Copy the last section down below (see sample): <PaletteEntry id="d26"> <References/> <Presentation name="B - Views" description="NX Example, 4 Views, 2 Sheets"> <PreviewImage type="UGPart" location="drawing_views_template.jpg"/> </Presentation> <ObjectData class="DrawingTemplate"> <TemplateFileType>none</TemplateFileType> <Filename>B-views-template.prt</Filename> <Units>English</Units> <UsesMasterModel>Yes</UsesMasterModel> </ObjectData> </PaletteEntry> and edit as follows. <PaletteEntry id="d26"> Change the "d" number to a unique number (one not already used in the file). For this example, change it to "d27. <Presentation name="B - Views" description="NX Example, 4 Views, 2 Sheets"> Change to desired ouput. <PreviewImage type="UGPart" location="drawing_views_template.jpg"/> Change "location: to point to a preview image. To create the image, use File--> Export --> select image type to export such as jpg, etc. BMP is notsupported. You can also specify the template part file and the embedded imagewill be extracted. The file types .prt, .fem, .sim, .bkm, & .plmxml aresupported. <Filename>B-views-template.prt</Filename> Change to the correct file name. <Units>English</Units> Change to Metric if needed. Remember to back up any new/modified files as they could be overwritten wheninstalling upgrades.
