technology with a 3D modeling capability serves as a backbone in the design process in a manufacturing industry.
Here, iLogic serving as an add-on of Inventor software will be combined with a Decision Support System (DSS) to build a DSS application system, namely "Panel Auto System".
This system will help an engineer modify a 3D model wall-mounting panel to fulfill a non-standard order from his or her customers.
This 3D-model database from various parts of the wall-mounting panel is generated from the 3D modeling.
Then, by employing the if/then/else rules in the iLogic, the system can modify a 3D model wall-mounting panel data standard and serves as a geometric 3D model based on the customerAos order.
The system works well and has been validated.
The efficiency of the modeling process using the "Panel Auto System" increases its time efficiency up to 97,6 % compared to a manual process.

This is an open access article under the CC BY-NC license INTRODUCTION Commonly practiced in the manufacturing industry, the modeling process of both sketchbased 2D and sketch-based 3D modeling usually employs a manual and a digital technique such as CAD.
In this modern era, the 3D model has grown rapidly and can be learned.
Moreover, it also serves as a media aiding various human For instance, we use virtual engineering models to improve our spatial skills and gain a better knowledge of 3D contours .
in a manufacturing process.
Currently.
CAD/CAM also serves as one of the backbone technologies in industry 4.
0 pillars since it specifically serves as the input data for augmented reality.
Augmented reality is also used to simulate a manufacturing process in a computer, known as virtual manufacturing .
Virtual manufacturing has several benefits such as reducing material waste while lowering costs and lowering the risk of poor design, too .
Virtual manufacturing is a computer system capable of producing the same information on the structure, state, and behavior of a manufacturing system as we see in the real manufacturing system.
moreover, it is also capable of reducing material waste while lowering costs and lowering risk because of the design and manufacturing process planning errors .
Industry 4.
0 in an industrial activity is realized through a "smart manufacturing" -- a manufacturing system that can meet and exceed the challenges of today's manufacturing systems by cyber-physical system (CPS) implementation among the machines in a factory.
It is capable of eliminating boundaries and limits by shortening the product manufacturing cycle and adjusting the product manufacturing through a competitive method .

June 2022: 193-200 To generate a work item, a manufacturing process typically uses several tools particularly for machining.
3D printing is a kind of technology that can help in a manufacturing process .
It is an evolution in the manufacturing sectorial lines gradually displaying its most recent innovations with each line through continuous improvement and diverse best practices .
CAD technology is also implemented in the design and manufacturing of an electrical An electrical panel is a cube-shaped object of various sizes with its side containing a power gauge and limiter and an electrical panel containing equipment for the distribution of electrical power or connecting equipment .
electrical panel also serves to handle the current or flow of wild electricity with a grounding in order that it can be secured and will not give any harms .
The 3D CAD is beneficial in the designing of an electrical panel.
Many faults and losses occur due to an electrical installation and electrical setting error .
If the dimensions of an electrical panel do not comply with the standard, they may negatively impact on the operational costs due to waste of electricity.
Moreover, it is possible for the factory to undergo breakdown due to an electrical installation error or a non-standardized electrical panel.
Using a standard electrical panel also provides us some benefits in that it makes us easier to maintain the electrical installation maintenance system .
and to keep the machines at the factory from being damaged due to an unstable power supply or a frequent breakdown.
The size of the electrical panel increases proportionally to the increasing demand for a changing electrical power due to various aspects such as the number of the electrical components, the size of the room, and the factory standard to which the electrical panel will be installed.
The need for the size of an outside-the-standard panel which still guarantees safety requires flexibility in the design process of an electrical It requires a flexible system which does not extend the design time .
A mechanical and an electrical panel usually have an IP code on the device nameplate to determine the specifications of the panel.
code (Ingress Protectio.
is a kind of protection for an electrical device inside the work system of a protection panel or device, and it represents resistance to the direct contact or penetration of an electrical device by a foreign material such as water or dust .
Currently, the design of an electrical panel is made by complying with the IP standards using CAD - Inventor software.
Moreover, the database is available.
However, the customer sometimes asks for a design with a slightly different size from the standard size, so the designer has to make several modifications resulting in a longer time consumed and prolonging the manufacturing time.
Hence, this situation creates a problem, and the solution to this problem is creating an application program compatible with CAD - Inventor software.
The application program is a 3D modeling supported by Decision Support System (DSS).
A designer can use this application program to help him or her decide on which type of panel design will meet his or her customersAo requests and his or her minimum modification efforts .
Combined with the CAD-I inventor software, this application program serves to shorten the design modification time.
This application serves to make a component and an assembly on an electrical panel to be mounted on the wall.
The designer can later use the application by filling out the forms provided to modify the required electrical panel, and the 3D modeling process will automatically be done, making it faster and more Decision Support System (DSS) is an information system designed to help businesses store, manage, analyze.
Eventually, it helps a manager to make his or her decision .
DSS
employs a summary of information, exclusions, patterns, and trends using an analysis model.
DSS helps a manager in his or her decisionmaking process.
However, it does not have to make a decision by itself.
There are two types of decision-making processes: programmatic and non-programmed.
A decision-maker collects useful information from raw data, documents, personal knowledge, and business models to identify and solve a problem and make a The major components of a DSS include a development process .
, and they are built with a thorough data analysis, an analytical and statistical research, an evaluation of alternatives, and evaluation of decision optimization criteria, all of which may necessarily be significant and may require an exhaustive investigation given that a DSS comprises four primary components, namely a user interface, data, model, and knowledge base .
Then, from the generated DSS system, the conceptual design will be selected from the ifthen-else rules from iLogic.
ILogic technology enables an engineer to develop a library of standard and standard products in a CAD program in order to get a quick rebuild of the geometry of a product based on a CAD program calculation as soon as a specification in the source data is changed .

Decision Support System (DSS) for modification of A p-ISSN: 1410-2331 e-ISSN: 2460-1217 The iLogic programming language, which is comparable to a scripting language, is utilized when If-then-else rules, select-case decision trees, and loops are all common constructs.
Sub functions and sub procedures can be utilized in the code, and variables can be used both globally and locally.
For the sake of practicality, in every modeling scenario, the Inventor has a snipped library .
The program design will be based on the conceptual model having been selected from the iLogic rule result.
In most cases.
CAD software will translate the conceptual design into a 3D model .
This system is part of a new generation of a computer-aided design (CAD) system actively promoting a design decisionmaking environment and a problem-based learning strategy.
A meaningful internal objectbased representation of the 3D model designed within its context environment is the most important of these .

It is a protective component employed if the panel specification requires an IP_B to avoid any fluid when tested.
Database Parameter The parameters used are the data having been inputted as a value or a text in which it can be added, delimited, or duplicated as a rule to be used as shown in Figure 3.
The parameters used in this system are:
Dimension parameters.
They are data on the size dimensions used to set the height, width, depth, and size required by the system.
Boolean parameters.
They are parameters used in a Boolean operation in the modeling of a CAD.
The parameters of a Boolean operation to be used in the building of a 3D panel model are obtained by specifying trueor-false based options provided by the Decimal parameters.
They are numerical data forms used by the system to determine the IP_A and IP_B.
Description parameters.

iLogic Flowchart.
The program will be started by entering the data input of the height dimension of the 3D model panel with the options as follows:
input in the form of size data .
If High < 500 then High = 500 If High > 1200 then High = 1200 It means that the height of a wall-mounting panel is limited to sizes ranging from 500 mm to 1200 mm following the size of a panel already existing in the manufacturing standard.
The next step is to input the width dimension option as mentioned If Width < 300 then Width = 300 If Width > 900 then Width = 900 The statement above means that the width of a wall-mounting, 3D model panel is limited to sizes ranging from 300 mm to 900 mm following the size of a panel already existing in the manufacturing standard.
Afterwards, the next step is to input the depth dimension option.
If Depth < 200 then Depth = 200 If Depth > 400 then Depth 400 The statement above means that the depth of a wall-mounting panel is limited to sizes ranging from 200 mm to 400 mm following the size of a panel already existing in the manufacturing Rahman and S.

Decision Support System (DSS) for modification of A p-ISSN: 1410-2331 e-ISSN: 2460-1217 Then, the next step is to select an indoor or outdoor form option.
Input in the form of Description "INDOOR" or "OUTDOOR".
If Location = "OUTDOOR" Then Canopy = True Else Canopy = False If the input value is at location AuOUTDOORAy, then the Part Canopy will be active.
Meanwhile, if the value is other than that value, the canopy will be If Location = "OUTDOOR" and (Incoming = "TOP" And Outgoing = "TOP") Then Canopy = False Location = AuINDOORAy It is a special or additional decision if the location value is "OUTDOOR", and the incoming and outgoing value is "TOP" since the canopy will be deactivated and will return to the "INDOOR" input Input in the form of information "TOP" or "BOTTOM" in each column.
If Incoming = "TOP" And Outgoing = "TOP" Then TOP plate = True BOTTOM plate = False Else BOTTOM plate = True The statement above means that when the incoming and outgoing input values are the same as "TOP", then the cover plate and the hole on the top will be active.
Meanwhile, the plate and the hole on the bottom will be inactive if the input values are other than AuTOPAy.
If Incoming = "BOTTOM" and Outgoing = "BOTTOM" Then TOP plate = False BOTTOM plate = True Else TOP plate = True The statement above means that if the incoming and outgoing input values are the same as AuBOTTOMAy, then the cover plate and the hole on the bottom will be active.
Meanwhile, the plate and the hole on the bottom will be inactive if the input values are other than AuBOTTOMAy.
The next process is selecting the number of IP_A.
The number of the IP_A selected will determine the diameter of the ventilation holes.
Input is Decimal .
,2,3,.
= 4 inputs.
(IP A is limited to IP 4X) If IP_A = 1 or 2 Then Ventilation Hole = 5 If IP_A = 3 Then Ventilation Hole =2.
5 mm If IP_A = 4 Then Ventilation Hole = False Next, the statement below is used to select the numeric of IP_B.
The numeric of IP_B determines the type of rubber and its thickness to be used.
Input is Decimal .
,1,.
= 3 inputs.
(IP B is limited to IP X.
If IP_B = 0 Then Rubber = False If IP_B = 1 Then Rubber =0.
5 mm If IP_B = 2 Then Rubber = 2 mm Both IP_A and IP_B are in accordance with the existing reference of the IP standards.
The next step is to input the Boolean data form.
Input in the Boolean data form (Yes/n.
If Ventilation = AuNOAy Then Feature Ventilation = False Else Then Feature Ventilation = True If the value of the ventilation parameter is AuNOAy, then the ventilation hole feature will be disabled which means that there are no If the value is other than that value, the feature will be active.
Next, the logic is combined and realized in the iLogic program provided by the Inventor software and uses the parameters having been prepared by employing the add rules, so a coding program will be generated as shown in Figure 5.
