In the
bottom there are 3 main buttons:
Find
sheet metal parts –
searches through assembly structure and lists all sheet metal parts
in the list
Flat
patterns preview –
creates thumbnails of flat patterns
Export –
creates DXF or DWG files of flat patterns of selected sheet metal
parts
The way
how Find sheet metal parts and Export commands work
is set in Settings and Layers tabs.
Finding sheet metal parts
Click
Find sheet metal parts command to list all sheet metal
parts. Based on the settings the command will find and list
all the sheet metal parts and/or create missing flat
patterns. The result of the operation is shown in the image

Customizing list appearance – sort, order, size and select
columns
You can
click on column names to sort the components by the value in
the specific column.
You can
reorder the columns by drag and drop on new location:


You can
resize the columns by dragging the column edges:

You can
show and hide the columns by right clicking on column
header:

Click
Reset to change the list to default view – default order,
size and visibility of columns.
Check bend line lengths

Checking
this option in Settings tab will mark the sheet metal parts
of which any bend length exceeds the one you specify in Max.
allowed bend line length. This is useful if you want to quickly
identify the parts that are too large to be bent on a specific bend
machine. Following image shows that all the components with at
least one bend longer than 500 mm are marked yellow:

Manage custom iProperties
In
addition to base properties you can include any number of custom
iProperties. Click Add Custom iProperties… to manage the
included custom iProperties:

Clicking
the button opens custom iProperties dialog. Following screenshot
already includes 2 custom iProperties:

Adding
custom iProperties:
Click
button and enter precise name of the custom
iProperty you wish to include.
Deleting custom iProperties:
Select the
property and click
button or press DELETE button
on keyboard.
Click OK
to close the dialog and to add new properties to list of sheet
metal parts. To update the values for new custom iProperties you
have to run Find sheet metal parts command.

New custom
iProperties are also added into panels for defining the
DXF/DWG naming structure and properties included as texts in DXF files.
Automatic creation of flat patterns

Automatically create flat pattern if it doesn’t
exist – if the tool
finds sheet metal part without flat pattern and this option is
selected the flat pattern will be created automatically.
This is
also valid for derived sheet metal components that were created
using Make Components tool from master multibody sheet metal
component. In this case it’s required that “Link Sheet Metal
Styles” option is checked when creating components using
Make Components tool.
Auto-detect and unfold assembly mirrored sheet metal
parts – creates flat
patterns for sheet metal parts that were created using
Mirror tool in assembly.
Sheet
metal style and thickness are automatically read from parent sheet
metal component. The style must exist in Sheet Metal Style library
to make the automatic flat pattern generation work.
Generating flat pattern previews
AutoDXF
enables you to see the shape and orientation of flat patterns in
one place before exporting them to DXF/DWG. Contrary to thumbnails
of 3D models the thumbnails of flat patterns are not saved within
IPT files so they have to be generated before they are
displayed.
There are
2 ways to generate the flat pattern thumbnails:
-
Manually
for selected row by right
clicking on a row and selecting Flat Pattern Preview command
from menu

-
Automatically
for all sheet metal components
by clicking on Flat patterns preview button

Automatic creation of flat
pattern thumbnails can take some time for
assemblies with lots of sheet metal parts. You can stop the process
by pressing F12 key.
Flat pattern thumbnails are not linked to components – if the
geometry changes you have to manually take care of regenerating the
thumbnails.
|
After the thumbnails are generated they are displayed in the FP
preview column:

You can
zoom the flat pattern previews by clicking+holding the left
mouse button over flat pattern images:

Working with flat patterns
Right
clicking on a row opens a menu with commands for manipulating flat
patterns.

Open part

adding text descriptions is not supported
when exporting to DWG. Use DXF format if you wish to add text
descriptions into exported flat pattern
files.
|
You
can see the exporting progress in bottom left corner of the AutoDXF
window:

DXF/DWG
geometry settings, layers settings and file naming are based on
selected options in Settings tab.
All the settings you make in the Settings
tab are automatically saved when you exit the
program.

DXF/DWG save location

In this
section you can set where the DXF or DWG files are saved. There are
2 options:
Same as
IPT document
In this
case the exported files are saved in the same folder as parent IPT
file.
In
folder
All
exported files are saved in a selected folder. Select the folder by
clicking
button or click
to select the folder of current
assembly.
Option
Create subfolders by thickness enables saving DXF files in
subfolders based on sheet metal thickness. In this case you get
DXFs grouped by their thickness.
Option
Create subfolders by material enables saving DXF files in
subfolders based on material. In this case you get DXFs grouped by
their material.
If both
options are checked the first subfolder level will be thickness and
the second will be material as shown below:

Overwrite existing files: if this option is checked all existing DXF files
with same name as new ones will be overwritten. If the option is
not checked new DXF files with same name as existing will get
sequential number at the end of the name.

Automatic detection of threaded holes
AutoDXF
can automatically detect thread holes on flat patterns.

If Put
threads on separate layeris selected then all threads will be
placed on a separate customizable layer when exporting to DXF
format. You can change the thread layer name and color (Layer
name and Layer color).
Create
points in thread centres defines that Point objects are created in centres of
threaded holes.
Auto detection of threads is
supported only when exporting to DXF
format.

DXF/DWG file naming
You can
specify DXF/DWG file naming system in this section:

You can
select which properties to include in the file name by selecting
them in file naming table (image above).
All the
properties that are checked will be included in DXF/DWG file
name.
You can
also change the prefix (green column) – that is fixed text
that will be written before specific property.
The
properties that can be included are listed in property column.
Those are: IPT File Name, Material, Thickness, Quantity,
Part Number, Stock Number, Item, FPlength, FPwidth, Project
and Description.
The table
also contains optionally added custom iProperties.
The
properties are divided by selected divider in Divider
dropdown:

You can
change the order of properties by dragging and dropping.
Part number is put in front of Thickness in the example
below:

Some
examples of file naming:

It’s recommended to include
“IPT File Name” property in file name to ensure that exported files
will have unique names. If you build the file name expression in
such way, that there is possibility that some files will have the
same name, then uncheck the option
“Overwrite existing files”.
|
DXF texts
You can
include text descriptions in generated DXF files. Checking Add
text descriptions to DXF will enable this option.
Please note that adding text
descriptions is not supported when exporting to DWG.
|

Available
properties to include as texts are listed in Property
column: Material, Thickness,
Quantity, Part Number, Stock Number, Unit, Item and
Project.
Aditionally there are also added custom iProperties available in the list.
Properties
that are checked in “select” column will be included in DXF
text.
You can
change the prefix (green column) – that is fixed text that
will be written before specific property.
You can
change the order of properties by dragging and dropping them
up and down the list.
The text
is created on a specific layer. You can set its name in Layer
name text box. The color of text layer is defined using
Layer color dropdown.
Example of
text included in DXF file:

The text
is positioned approximately in the middle of flat pattern
geometry.
The text
height is defined in basic.autodxf.settings.xml
settings file.
Flat pattern settings
This area
includes the settings regarding creation end export of flat
patterns:

Combine
profiles in polyline – lines and arcs will be joined to polylines.
Replace
splines with line segments – splines will be approximated using linear segments with
selected tolerance. Approximation precision is controlled with
Tolerance value.
Rebase
geometry to 1st quadrant – all the geometry in DXF will be created in
1st quadrant so all the X and Y coordinates are
positive.
Length units

You can
select the length units for displaying sheet metal thickness, flat
pattern length and flat pattern width in list of found sheet metal
parts. A restart of AutoDXF is required after changing this
setting.
General settings
Click the
button to open the Windows Explorer in folder
where AutoDXF settings are saved.
Reset to default
Deleting
following .ini files: customiProps.ini, DXFime.ini,
DXFopisi.ini and WordSettings.ini from settings folder resets
AutoDXF settings for file naming, DXF texts and custom iProperties
to default.
Setting text size and decimal places
There is an XML setting file basic.autodxf.settings.xml in settings
folder. It includes settings for defining text heights for texts in
DXF files and settings for number of decimal places and trailing
zeros used for displaying flat pattern lengths, widths and sheet
metal thickness. You can open the file in any text editor (e.g.
Notepad) and edit the values.

Note that you can define text heights as fixed
values or as percentage of size of exported geometry. By default
text sizing is set as fixed (as in screenshot
above).
If you
wish to set text height according to overall size of the geometry
uncomment the tag
<textHeightPercentage>2</textHeightPercentage>, so it
looks like this:

It this
case the text size will be set at 2% of max. pattern
size.
You have to restart AutoDXF to enforce changed settings.
Language setting
You can
select English or Slovenian language of user interface in
Settings tab. After selecting the language please restart
the AutoDXF to fully apply the language change.
