CAD Room Procedure and Working Flow Chart in Apparel Industry
Pattern/ CAD Room SOP, Procedure, and Working Flow Chart in the Apparel Industry
CAD, computer-aided design, and garment patterns are made on a computer using different CAD software. CAD is the 1st step of Garment manufacturing, garments measurement control, shape, and pattern can be controlled easily. Here I am giving CAD room working procedures from starting pattern making to bulk marker printing flow chart-wise, your concept will be clear about CAD work and what they have to do in the Garments industry. Here we present Pattern or CAD Room Procedure and SOP, Working Flow Chart in the Apparel Industry.

Purpose of using CAD in Garments:
- To reduce time in marker making.
- To reduce Marker Wastage.
- To increase marker efficiency.
- To make the marker accurate.
- To calculate the fabric consumption accurately.
- To reduce fabric waste and maximum utilization.

Bulk cutting
Note: The whole process flow chart for new order development, when you do rebuy/ repeat order for the same style you may not need to do consumption and marker making again.
CAD Section/ Department Flow chart SOP is described briefly:
Initial tech pack/PDM receives from merchandising dept.:
Firstly have to know about the tech pack / PDM (Product development Method) sheet. The sheet that contains all detailed descriptions of a definite garment is known as the tech pack/PDM sheet. The CAD section collects it from the merchandiser at first.
Create a new Pattern:
In this step, the CAD department develops a pattern according to tech pack requisition. “Pattern” is a hard paper that contains all single parts of a garment.
Calculate fabric consumption by an electric mini marker in yds:
Consumption means – How much fabric is needed to produce a garment. With the revolution of scientific invention nowadays it does not need to calculate manually. It is already calculated by CAD section automated Lectra/Gerber/Red tree software.
Send consumption to Buyer:
After calculating the consumption, the report is sent to the buyer for approval. The less consumption you can submit the more chance to get an order for those styles.
Consumption Approval:
If the buyer is satisfied with the consumption report, Then the buyer approves the report and agrees to place an order.
Order Confirmation:
Here Order is confirmed by the buyer. If the buyer confirms an order, the garments maker may go forward with the next process.
Receive E-Pattern, Block, and fit sample from a buyer:
As per the CAD section SOP, the section receives E-pattern, Block, and fit samples from the buyer. A block sample means the pattern without allowance. Fit sample means the sample fit for a dummy.
Pattern Grading
Grading means the size variation from the master size. Firstly a pattern is created with the standard Size, then it would be graded according to all sizes. suppose, S, M, L, XL, and XXL sizes are ordered. L is the master size pattern. Then S, M, XL, and XXL are created based on master size.
Submit to the buyer: After completing grading the complete pattern is submitted to a buyer for approval. If Approved, then go for marker making for a sample. If not, it will be rejected, and comments for the remake.
Marker Making for a sample:
For Sample making marker is created. A marker is a thin piece of paper that bears all the parts of garments. Here Marker is created by CAD software.
Shrinkage and sewing loss adjustment:
During pattern making, they adjust the shrinkage and sewing thread loss tendency at the warp and weft direction.
- Sample Making for bulk production: Now the sample is created for bulk production.
- Approve sample from buying a house: In this step, The sample for bulk is approved for buying the house. Then go for bulk.
- Marker making for size set: According to the required size, the marker is produced by CAD.
- Marker Printing: Now the created marker is ready for print.
- Cut size set: Size set marker used for trial cutting. Then check measurements before and after washing.
- P.P meeting: P.P means (pre-production) meeting. Here the P.P meeting was arranged so that styling never be a mistake.
- Pattern Correction: If any problem is found in the size set, In the P.P meeting the solution will be given where the pattern would be correct. Excessive or uncontrol correction would deform the garment shape.
- Marker printing by Plotter: The plotter machine is used for marker printing. The completed marker is printed through it.
- Send marker to cutting: The Marker is ready to send to the cutting section.
- Marker lay: After spreading the fabric on the cutting table the marker is placed on it. Before Cutting the marker is checked very carefully, whether any parts or sizes are missing or not.
- Bulk cutting: If everything is okay then bulk cutting starts. A straight knife or a round knife is used to cut. During cutting Production proper tension should be maintained.
CAD is the center point of how a garment should be in terms of sizes, shape, measurement, marker making, and fabric utilization. Pattern/ CAD Room SOP, Procedure, and Working Flow Chart in the Apparel Industry concludes here.
