CAD function collection.

Common information

Here are collected most useful functions for CAD modeling.


Isomitric Pick angle Mirror Break apart Force fillet Create dimensions Sendwich group Flange Create shapes Page combiner Center of mass Numbering Drainage holes Mount holes Import files Create contour	Change curve direction Cut from curve Break to equal parts Delete segment Export segment Duplicate path Delete path Export path Show holes Change curve direction	Node extension Set first node Two points information Create tangent Create perpendicular Create bisector Connect two points Move point

Automation

You can built CAD function in your macro using this manual. Or you can add any CAD function to toolbar or assign Hotkey
If you have a need to integrate CAD function in your macro, it"s easy enough to do - there is a separate procedure. Initialize it and you"ll be able use any CAD function without need to start main CAD window.
Below I"ll show an example and list of parameters for this function. Example is for CorelDRAW X7 32bit, for any other version just change the name of the library:

Private Declare PtrSafe Function eCutPro Lib "c:/eCut/eCut/DLL/eCut17x86.dll" Alias "eCutPro" (ByVal f As Integer, ByVal f2 As Integer) As Integer
"eCut Function launcher with parameters
Public Sub FLauncher()
eCutPro 42, 1
End Sub

Here:
42 - CAD number
1 - CAD function from this list:

00 - Cut from curve, 01 - Break to parts, 02 - Delete segment, 03 - Extract segment, 04 - Duplicate path, 05 - Delete path, 06 - Extract path, 07 - Show holes, 08 - Two points info, 09 - Tangent, 10 - Perpendicular, 11 - Bisector, 12 - Connect two points, 13 - Move point, 14 - Iso left, 15 - Iso top, 16 - Iso right, 17 - Pick angle, 18 - Mirror, 19 - Break apart, 20 - Force fillet, 21 - Enroute fillet, 22 - Node extension, 23 - HotWire cutter, 24 - Make first point, 25 - Change curve direction, 26 - Route optimizer, 27 - FingerJoint box, 28 - FingerJoint shape, 29 - Create dimentions, 30 - Volume calculator, 31 - Sandwich group

Node extension

Node extension Changing the input point tangentially or at a right angle
Special corner form Transformation of all sharp nodes
Dog-bone inner corners Processing of internal corners for milling to assemble finger-joints
Kerf compensation Creating a small circle in all the inner corners
Fillet inner corners Processing only internal sharp corners
Fillet outer corners Processing of only external sharp corners
Remove island Removing an island when milling a step along the inner contour

Force fillet

Sendwich group

Very useful when you have many plates that ungrouped and you need to group each plate separately.

Create a contour

A convenient feature for preparing layouts for printing followed by plotter cutting.

It is also possible to cut off the background in simple images.

The function uses the built-in procedures for tracing and combining objects in CorelDraw, so the processing speed and result directly depend on this. Be sure to check the result.

Parameters:
Process - you can process each of the selected objects, either as a whole, or only images.
Order - you can create a contour under or above the object.
Weld shapes - corel has a couple of methods for welding all objects, sometimes some may be buggy, so you can choose the right one depending on the result.
Gap - if you set a negative value, the contour will be created inside.
Fillet - it uses the built-in corel function for rounding corners.
Images - the image processing method is set here (you can trace or use display/bound curve).
Process images - the plugin uses the features built into corel and they are sometimes buggy, so you can try to choose different image tracing methods depending on the result.
Fill and stroke are contour parameters.

Numbering

This function allows you to number all selected shapes.
Number can be created inside or outside shape.

Drainage holes

The function searches for places in objects where liquid can accumulate.
And puts markers in these places so that the backs of the signs can be milled in the future.

Mounting holes

Function for placing holes on the backs of letters along the guide-lines.
The function searches for the intersections of the backs with the horizontal guides in the coreldraw and places holes for fasteners.

Import files

Batch file import
Here you can quickly add a lot of files, if necessary, specify the number, and the function will import files into the document and each import will be marked with a file name.
