DXF topic: DXF page and import → Hole table and settings → DXF postprocessing → G196 bore-milling example

Machining Wizard calculates a path from entered dimensions; DXF takes positions from a drawing and adds machining settings. Both eventually return a program to the standard program page.

This chapter explains how the existing DXF entry, page and import script work together. Use the same four-hole drawing throughout this four-chapter topic. Continue with the hole table, postprocessing, then the G196 extension.

1. Enable DXF in the macro parameter window

The DXF switch is #929.item[12]. It is currently absent from the configuration menu: edit it yourself in the macro parameter window.

1. Sign in with developer permissions and open Parameter on the main screen.
2. Open Macro Param. in the function-key area. Positions are configurable, so find the function by name rather than assuming a fixed F-key. If it is not assigned to the panel, use the method in Function-key configuration to select it.
3. Find 929 in the parameter list and click its row. The upper table shows the parameter's main fields; the lower table shows its items.
4. Find #929.item12 in the item table. This spelling omits the brackets; it identifies the same item as #929.item[12] in a script.
5. Change that row's item value to the enabled choice, numeric value 1. Do not change parameter 929's main value, title, type or version.
6. Close the window. DXF appears on the main navigation bar. Exit the application normally when configuration is complete so the settings follow its normal save process.

The current English language pack retains Chinese text for some fields, including this item: DXF导图 is the DXF feature, 否 means No (0), and 是 means Yes (1). The screenshots preserve those actual labels.

The switch controls entry and page visibility. It does not choose a hole depth, tool number or coordinate system, or turn the drilling page into a contour-machining page.

2. Use four circles to understand the page

Download the four-hole DXF. It contains four independent circles, all on Z=0, without additional contours.

Click DXF on the main navigation bar, then Import DXF, and choose this file. DXF is a main entry alongside Program, not a fourth child page after Toolpath Preview, File Management and Machining Wizard.

Figure 3: NO.2 is selected and its Bottom Z has been changed to −7. The other holes use −5. Drag the page dividers to give the table and input area enough space.

In this version, the column labelled “Dia.” actually displays the DXF circle radius. The first three circles therefore show 2 and the fourth shows 3. Filter Dia. uses that same radius value. This chapter keeps the actual interface wording and explains the numbers the implementation reads.

3. How the entry becomes visible and the page loads

In env/maininterface/maininterface.ui, the DXF label is named label_49. Its relevant attributes are:

-A: (clickedEvent:/env/dxfpage[0](#810permission=7))
-C(#929item12==1)
-V0

Read them in this order:

• #929item12==1 tests whether the DXF switch is on.
• -V0 uses condition 0 to control visibility; the entry is visible when it is true.
• A click sets #810.permission=7 to select DXF, then runs /env/dxfpage.
• [0] selects the main Qt script channel, as in the earlier main-page examples.

Here is the complete env/dxfpage script:

IF#899.version==1GOTO1
#899.version=1
#899.itemdesc[0]="/env/dxf/dxf.ui"
widgetFunc["QFrame","dxfframe","refresh",""]
N1

#899.itemdesc[0] supplies the UI path. The main window's dxfframe loads that page. Here, #899.version means “already loaded,” avoiding reconstruction on every click. The main frame also checks #810.permission==7 and the DXF switch when deciding whether to display the area.

This repeats the multipage method: the entry changes a page-selection parameter, the frame controls visibility, and a script loads the UI on first use.

4. Match the buttons to their scripts

The page file is env/dxf/dxf.ui. Use this table to find the starting point for each operation.

All scripts in this table are under env/dxf/. Import DXF and Save/Load use mouse-release events; the other listed buttons use click events. When tracing a button, inspect its event attribute rather than guessing a filename from its caption.

This topic also includes the complete import script, generation script and save/load script, for reading alongside this chapter and the following chapters.

5. What importing a drawing actually creates

dxfloader opens a file picker, then uses two built-in operations. Its opening section is:

#100=""
widgetFunc["openFileName","*.dxf","",100]
IF#100==""GOTO2
widgetFunc["readDxf",#100,"",0]

#100 receives the selected path. The script then joins #6002.item[0] through #6002.item[9] into a colon-separated string of default settings and calls:

widgetFunc["dxfDrillInit","","",#6001.description]

The responsibilities are distinct:

1. readDxf reads geometry. File entities enter the software's internal drawing data.
2. dxfDrillInit creates the drilling list. It extracts centers and radii from circle entities across the drawing's layers, creates #6001 records and draws the circles.
3. dxfloader prepares per-hole settings. It allocates one item per hole in #6003 through #6012, then copies defaults, input types and option text from #6002.

Reading an entity does not automatically make it a drilling hole. This page selects circle entities. A closed polyline or several arcs that look like a circle do not automatically enter this hole list. The page also has no input for choosing holes by layer name.

Reimporting rebuilds the list and per-hole settings and clears the old Body text. Save an NC result before reimporting if you want to keep it. To keep a set of defaults, select the appropriate hole and click Save Params first.

Read the import script's two loops

The configuration does not allocate ten consecutive parameter numbers for each hole. Each setting has one parameter number; different holes occupy its different items. All bottom-Z values are in #6007, for example, and all feeds are in #6012.

The import script first clears the item counts of #6003 through #6012, then sets each count to the number of holes. Its outer loop visits holes; its inner loop copies the settings:

#[6003+#6002.channel].itemunit[#6002]=#6002.itemunit[#6002.channel]
#[6003+#6002.channel].itemtype[#6002]=#6002.itemtype[#6002.channel]
#[6003+#6002.channel].item[#6002]=#6002.item[#6002.channel]

Here the main value of #6002 temporarily holds the hole index, and #6002.channel holds the setting index. The defaults themselves remain in #6002.item[...]. For the original NO.2's feed, the hole index is 1 and the setting index is 9, so the third line means:

#6012.item[1]=#6002.item[9]

The first two lines also copy the input type and option labels. Copying defaults therefore involves more than values: to create a combo box, the table needs an option-type definition and its choice names. After import, every hole has its own values; editing NO.2 changes neither the defaults nor NO.1.

6. Troubleshooting

Imported holes now have indices and their own default settings. The next chapter uses those values to explain table selection, drawing highlights and the right-hand inputs.
