Importing DXF (hierarchical) Files
from web site
The process for importing each format is generally the identical, however the obtainable options differ. For a step-by-step tutorial on importing a layout file, refer to Importing a Layout. For particular import options related to importing DXF files, seek advice from Import DXF (hierarchical) Options. For information on mapping DXF recordsdata to EGS Archive recordsdata to Ads recordsdata, discuss with Mapping DXF to Ads.
In an effort to import a DXF file, you should use the DXF (hierarchical) translator versus the DXF (flattened) translator. When importing recordsdata utilizing the DXF (hierarchical) translator, the program first accesses the DXF file. This file is then translated into EGS Archive file format as shown in Figure 3-1. The file can then be opened up in a sophisticated Design System Layout window.

Import DXF (hierarchical) Options
This section describes the definable options accessible for importing recordsdata in the DXF hierarchical format.
File >Import >DXF (hierarchical) >More Options
The Import DXF (hierarchical) Options dialog field lets you specify Unit Conversion, Attributes, Arc Extrapolation and Layers to manage the import of DXF format files.
Unit Conversion
Unit conversion must be specified for both the DXF file and EGS Archive file. The AutoCAD Units (DXF file) and Ads Units (EGS Archive file) drop-down menu selections show the out there items. These items are described in Table 3-1. Table 3-1. Available Units Unit
Meaning
um micrometer
mm millimeter
cm centimeter
mil mils
in inches
AutoCAD Units
Specifies the DXF file's items. This info just isn't included within the DXF file. The default is mil.
Ads Units
Specifies the EGS Archive file's models. The default is mil.
Attributes
The Attributes part lets you set an auto scale and/or the ability to link zero-width parts.
Auto Scale
The Auto Scale attribute is used to robotically scale each length in the DXF file to the desired Ads models. The default is lively.
Link Zero-Width Elements
The Link Zero-Width Elements attribute is used to merge adjoining line segments into polygons. This feature is very useful when sending information to Momentum, because Momentum can only mesh and simulate bounded components. The default is active.
For more info on Momentum mesh and simulation, check with "Mesh" and "Simulation" in the Momentum guide.
Arc Extrapolation
The Arc Extrapolation part lets you optimize arcs for a specific utility.
Arc Resolution (in degrees)
The Arc Resolution defines the arc segment in degrees. dxf file of the Arc Resolution, the smoother the arc. The default value for Arc Resolution is 5 levels.
Figure 3-2. Arc Resolution
Arc Sag Distance
The Arc Sag helps to compensate for the triangle flat attributable to each of the arc segments. By working with the dimension between the flat and the peak of the arc, the arc becomes step by step smoother. The default worth for Arc Sag Distance is 0. The items for Arc Sag distance are defined in the Unit Conversion section.

Layers
When importing giant DXF recordsdata, you can save invaluable computation time by including only specific layers. The next fields enable you to pick explicit layers that you want to incorporate in your import. In order to obtain info in regards to the DXF file's layers, Ads scans the DXF file and stores the layer info in a .lyr file of the identical identify. If no DXF file was specified within the Import dialog field, the Layers choices are left desensitized. If a DXF file was entered and Ads has already created a .lyr file for it, the list of layers is mechanically displayed in the Include Layer(s) discipline. If a DXF file was entered but Ads can not discover a .lyr file for it, no layers are displayed and the Search for Layers button becomes active.
Include Layer(s)
This area displays all of the layers found throughout the DXF file. From this record, you possibly can select particular layers to incorporate when importing the file. If no specific layers are selected, Ads will import all layers by default.
Select All / Deselect All
Click the Select All button to pick out ALL layers for import. Click the Deselect All button to deselect ALL layers for import.
Seek for Layers
If Ads can not find a .lyr file with the identical identify as the import file, this button turns into lively. Clicking this button causes this system to scan the DXF file and produce a .lyr file containing data concerning the file's layers. Once the .lyr file is created, the Include Layer(s) field is up to date with the entire layers found within the DXF file, the Search for Layers button turns into desensitized, and also you are now ready to choose specific layers to incorporate in your import.
Mapping DXF to Ads
