Creating Part Design Hole Standards

When defining Holes, we ahve to key in values for all of the fields which can become very repetitive and even troublesome from human fallibility standpoint. Out of The Box there is a way to define sets of Standard Hole sizes for the Five Types of Holes; Simple, Tapered, Counter Bored, Counter Sunk and Counter Drilled. This will allow you to select a Standard from the dropdown menu in the Hole Definition dialogue window, which will automatically fill the values for Main Diameter, Depth, Counter Bore Diameter, Counter Bore Depth, Thread Pitch, Thread Diameter etc.

Folder Structure

You must store hole standards .xml files in separate directories under the following directory.

<Installation>\resources\standard

You must create the following directories under the standard directory.

SimpleHole to store simple hole files.
TaperedHole to store tapered hole files.
CounterSunkHole to store countersunk hole.
CounterDrilledHole to store counter drilled hole.
CounterBoredHole to store counterbored hole.

XML File Structure

Within the XML File Structure is comprised of three chunks;

Units
Type Definition
Type Value

Units

This section defines the used Units within the Type Definition

	<std:node name="Units">
		<std:node name="Length">
			<std:strval name="Length">mm</std:strval>
		</std:node>
		<std:node name="Angle">
			<std:strval name="Angle">deg</std:strval>
		</std:node>
	</std:node>

Type Definition

This section defines the structure of the Hole Type and the Attributes that can be Valuated within the XML file. I would recommend setting all of the values to 0.0 for the Float Values, 0 for the Int Values and set the Name and Description to Base<HoleType> i.e., BaseCounterDrilledHole, so you don’t confuse this with an actual set of values for a specific hole type.

<std:typedef name="CounterDrilledHoleValues">
		<std:strval name="Name">BaseCounterDrilledHole</std:strval>
		<std:floatval name="MainDiameter">0.0</std:floatval>
		<std:intval name="Mode">0</std:intval>
		<std:floatval name="CounterDrilledDiameter">0.0</std:floatval>
		<std:floatval name="CounterDrilledDepth">0.0</std:floatval>
		<std:floatval name="CounterDrilledAngle">0.0</std:floatval>
		<std:floatval name="CounterSunkDiameter">0.0</std:floatval>
		<std:floatval name="BottomAngle">0.0</std:floatval>
		<std:floatval name="ThreadDiameter">0.0</std:floatval>
		<std:floatval name="Pitch">0.0</std:floatval>
		<std:strval name="ThreadDescription">BaseCounterDrilledHole</std:strval>
	</std:typedef>

Type Value

The last section contains the individual Hole definitions, the Name attribute must be unique, I would recommend starting with Sample1 and Sample2 to get used to how this file works with the Hole function.

		<std:typeval name="CounterDrilledHoleValues">
			<std:strval name="Name">Sample1</std:strval>

Managing XML File Change

You can edit the XML file in two ways;

XML File Direct Edit
XML File Edition Through the Standards Interface

XML File Direct Edit

The XML file can be directly edited with a tool such as ‘NotePad++‘, without restarting CATIA. As long as the either the Hole Type is Changed and then changed back or the Standard set to No Standard or another Standard and then set back the Standard will update in the session post XML changes once the file is saved.

XML File Edition Through the Standards Interface

Its important to note that if the ‘CollectionStandard‘ environment variable is pointed to a different directory than the <Installation>\resources\standard folder then once any edition is made a copy of the new file will be created in the ‘CollectionStandard‘ folder. When a duplicate file is found in the ‘CollectionStandard‘ folder this file is used by default.

To use the Standards Interface you must have ‘Leader‘ access. Then from the top right hand corner within the thick client select Preferences->Standards to open the Standards Editor. In the top left-hand dropdown select the Category and then select the XML file to edit.

Serializing and Deserializing the XML Files in C#

The following code will allow you to Deserialize the Standard Hole XML files into a class structure defined by the classes shown below. We can then add additional Standard Hole definitions and re-serialize the XML file again.

			string text;
            using (var streamReader = new StreamReader(@"C:\Users\ma_je\Desktop\Hole.xml", Encoding.UTF8))
            {
                text = streamReader.ReadToEnd();
            }

            Node? test = null;

            XmlSerializer serializer = new XmlSerializer(typeof(Node));
            using (StringReader reader = new StringReader(text))
            {
                test = (Node)serializer.Deserialize(reader);
            }

ViewModels

Eventually we will ahve a Nice User Interface where we can create new Standard Holes to do that we will need View Models, the following classes represent the required View Models.

Abstract Hole View Model

    public abstract class AbstractHole
