Visual can import CAD files in a DWG/DXF format. Below are some tips to assist with importing CAD files into Visual:
Importing CAD files with complex entities:
Some CAD files can consist of complex entities such as blocks, 3D solids, bodies and regions. These types of entities are too complex for Visual to import and need to be ‘exploded’ into simple entities such as a polygon or a line in the CAD software:
- In CAD software, select Explode from Modify menu.
- Select all entities in the CAD file and right-click to complete the command.
- Select Save As from the File menu and save as a DWG file (Tip: Save the file in a 2000 DWG format.)
- If you are still unable to import the file into Visual, then repeat steps 1 to 3 until the file imports in Visual (Tip: Complex entities may need to be exploded multiple times until they become a simple entities.)
Importing CAD files with external references (XREF):
An XREF is an ‘external reference’ to another CAD file. The following information explains how to attach an XREF to your CAD file:
- Type xref or xr into the command line at the bottom of the screen. This launches the External References window.
- To attach an XREF, click on the Attach DWG icon at the top left of the External References window.
- Select the reference file and then click Open.
- Select whether or not you want you want the reference file to be an Attachment or an Overlay (Choosing Overlay doesn’t include any of the nested XREF's associated with the reference file.)
- Select an insertion parameter by either selecting Specify On-screen or selecting the default values.
- Click OK.
In order to import a CAD file that has XREF's associated to it into Visual, the XREF's need to be either in the original location of when they were referenced or in the same location as the CAD file.
Tip: Create a folder that includes both the XREF's and the CAD file before importing the CAD file into Visual.
Checking for Large X and Y Coordinates:
Visual cannot handle very large X and Y coordinates (i.e. X=1,000,000, Y=1,000,000). If you import a CAD file with very large X and Y coordinates, you may find some of your information has disappeared from your background. Also, if you place a Plan or Architectural view of your design in the Print Editor, you will not be able to see it.
Tip: Before importing your background into Visual, move your background, in your CAD file, to X=0, Y=0.
