Automatic Hole Type Recognition

Setting of Automatic Recognition of Hole Types Color Attributes Linkage Hole Type Linkage

You can change settings that are useful when using meviy for each registered user. The following is a guide to set up the hole type recognition method according to the CAD software you use.

Caution

Automatic recognition setting, color attribute linkage, and hole attribute linkage are not supported for bore diameters (holes on the center axis) recognized as cutting round objects.

Automatic Hole Type Recognition Settings

Here are 3 settings to reflect the hole type of the 3D model in the meviy quotation.

Hover over your username and click [User Settings] from the User Menu.

Setup Method 1: No Automatic Recognition

With this setup, all cylindrical holes are recognized as through holes (sheet metal parts), and as straight holes with no tolerance (CNC Milling).
Specifications for tapped or precision holes can be changed after uploading the CAD data by opening the 3D viewer screen from [Next] and double clicking on the hole.

Caution

The original hole attribute information given in 3D CAD during model design is not retained.

Setup Method 2: Automatic Recognition of Tapped holes from Hole Diameter (Default)

This setup detects the hole shape and ‘hole diameter’ of the model according to your CAD software and automatically recognizes the tapped hole.
Please select your CAD software as the hole diameter requirement for tap hole recognition.
*If you have chosen to [According to File Type], the CAD used in the design will be estimated based on the file extension and the hole diameter will be matched.

Notes

See below for more information.
→［FA CNC Milling］Recognizing Different Types of Holes>”Recognizing Different Types of Holes“
→［FA Sheet Metal Parts］Hole Diameter Table>”Tapped Hole Recognition and Selectable Sizes“

Caution

The original hole attribute information given in 3D CAD during model design is not retained.

Setup Method 3: Automatic Recognition of Hole Type from Color Attributes

This setup detects the colored hole surface in the model according to your CAD software and automatically recognises the tapped hole, precision hole, etc.
The color attribute of each hole type can be registered in advance, and any hole type can be reflected in the quotation conditions by matching the coloration of the hole surface.

Caution

There are restrictions on the CAD data to which color attributes can be linked. (Reference: CAD information for color attributes linkage) Please select your CAD software and then upload the native format or an intermediate file (.x_t, .xmt_txt etc. for Parasolid only) output from the selected CAD software for use.
If you want the hole type to be recognized automatically, please register the color attribute in advance using the “Registration of Color Attributes” form at the bottom of the page.

"Registration of Color Attributes" for automatic recognition of hole types in meviy using color attributes of CAD data

If the automatic hole type recognition setting is set to [Automatic Recognition of Hole Type from Color Attributes], the RGB setting can be used to transfer the color attribute of the CAD data to meviy.

STEP1:

Select “Automatic Hole Type Recognition Settings” under user settings.

STEP2:

Set the hole type recognition method to “Automatic Recognition of Hole Type from Color Attributes”.
* You can only use the color attribute registration form if you have selected “Automatic Recognition of Hole Type from Color Attributes”.

STEP3:

Set up the CAD used.

STEP4:

Check the ON/OFF button for the hole type you want to set and activate the RGB entry field.

STEP5:

Put the values in RGB.
Note: RGB should be set at a value of 0~255.

STEP6:

Click “Update”.

	Items	Details
1	ON/OFF	It is possible to switch the setting on and off for each hole type.
2	Hole Type	This is a list of hole types that can be automatically recognized by color attribute linking.
3	RGB	This field is used to register the color attributes, with a value between 0 and 255 for each RGB.
4	Color Check	A message about the status of the RGB settings is displayed.

How to check the automatic hole recognition results and color attributes

To link CAD hole attributes and recognize hole types, please refer to the following rules.

STEP1:

Place the cursor on […] in the 3dviewer.

STEP2:

Click “Display automatic hole recognition results and color attributes”.

STEP3:

The list of holes in the details displays information about the linked color attributes.

*These color attributes are the result of meviy’s own analysis and may not match the values of the color attributes set in your CAD software.
Therefore, when you start using [Automatic recognition of hole type from color attribute], or when you change your CAD software, version, or environment setting, be sure to check the result of automatic hole recognition with this setting.
Also, use only the supported CAD and supported formats described below.

CAD Information For Color Attribute Linkage

Please refer to the following table for CAD data that can be linked to color attributes

Caution

The automatic recognition of hole type from color attribute is not guaranteed for models created with non-compatible CAD systems or formats.

Setup Method 4: Automatic Recognition of Hole Type from CAD Hole Attributes

This setup links the hole attributes created by the hole command (hole wizard) in your CAD software and recognizes the hole type.
Please select your CAD software and then upload the native CAD format.

Caution

There are restrictions on the CAD data to which hole attributes can be linked.

Application Rules for Hole Attribute Linkage

To link CAD hole attributes and recognize hole types, please refer to the following rules.

Applicable CAD software and file format

(1) Please create the file using the CAD software can be linked and upload it in its native format.

Regarding How to Create CAD Holes

(2) Linkable holes are those created by the hole command (hole wizard) in CAD.
(Please refer to the Hole Command Correspondence Table by CAD for the holes and attributes linkage.)
If the hole command is not used, the hole attribute would not be linked.

(3) We cannot guarantee correct linkage of customized hole command as operation has not been tested.
(Customize: Making changes existing standards or dimensions, Creating new standards, etc.)

(4) Only holes modeled by duplication commands circled in red can be linked.
However, in SolidWorks only, holes that are duplicated and then duplicated again are not recognized as holes created by the hole command and are not linked to Hole Type Linkage.

(5) The effective depths of tapped and precision holes will not be linked, and the dialog set information in user setting is applied.

(6) Metric thread holes are available, but not inch thread holes.

How to check automatic hole recognition results and hole attributes

Automatic hole recognition results and CAD hole attribute information can be checked on the 3DViewer.

STEP1:

The CAD hole attribute information is displayed on the right side of each hole in the tree view as [black text].

If the linkage failed, it will be displayed in [yellow text] with the notation “Unlinked Hole Attributes”.

STEP2:

CAD hole attribute information can be hidden.

STEP3:

Application Rules for Hole Attribute Linkage can be checked.

Caution

*These hole attributes are the result of linkage based on meviy’s own rules and may not match the hole attribute val ues set by your CAD software. Please be sure to check the results of automatic hole recognition when you start using [Automatic Recognition of Hole Types from CAD Hole Attributes] and when your CAD software, version, or environment settings are changed.
