How do I find a CAD file to download?

When you know the part number, enter the part number in the search tool in the upper right corner of any web page. Browse the first page of search results for the specific CAD file in the file type you need. If the specific file is not listed, select the link to the web page within the search results dedicated to the product series containing the item. Once on the product series web page, open the pull-down menu under CAD Files. First select the file type and then the specific item number. The typical file types available include DXF (2D), PDF (2D) and X_T (3D model - parasolid).

When you only know the product series for the required item, use the search tool to search for the product series or navigate directly to the web page for the product. Once on the product series web page, utilize the CAD file drop down menu as described above.

Not every product series on the website has CAD files available to download. The CAD Files' section will not appear on the web page when there are no CAD files available to download.

How do I search for part numbers?

Enter the LDI part number in the search box in the upper right side of any of the web pages. For best results, if the part number contains dashes, enclose the part number in quotation marks.  (ie. “VLT-20”)

What web browsers are compatible with the LDI website and its contents?

We have used Google Chrome, Mozilla Firefox and Internet Explorer for viewing the website without problems.  However, with Internet Explorer (especially version 11) there have been some issues with opening the Spec Sheets on the product series pages as well as the downloading of the CAD files.

Troubleshooting tips for Internet Explorer 11:

If you are trying to download a CAD file or open the PDF spec sheet and only get a blank tab, here is a link that we have followed to resolve this issue:


If you are trying to download a parasolid model and IE opens up a tab instead of downloading, you may need to right click on the file you want and then select "Save target as". You can then save it to the location of your choice.
