In Computer-aided design (CAD) software, patterns can be made efficiently and effortlessly. It is far easier than making in Pattern paper оr hand board.
So, are you looking at Pattern design for T-shirts on CAD software? Here is a worthwhile (Richpeace DGS) software that will help you a lot.
Software choice: RichPeace Garment CAD.

Measurement Chart for the T-shirt:
“M Size”
1. ½ Chest width = 52 cm.
2. ½ Waist width = 48 cm.
3. ½ Hem width = 49 cm.
4. UPPER Chest width = 39.5 cm.
5. Measurement height = 17.5 cm.
6. Front length = 70 cm.
7. Back length = 68.5 cm.
8. Upper back width = 40.5 cm
9. Measurement height = 10.5 cm.
10. Shoulder width = 12.5 cm.
11. Shoulder slope = 3 cm.
12. UPPer Sleeve length = 20.5 cm.
13. Sleeve cap height = 12 cm.
14. Armhole dept = 23 cm.
15. UPPER arm = 21.5 cm.
16. Neck width Seam to seam = 18 cm.
17. Васк neck drop = 2 cm.
18. Front neck drop from HPS = 11.5 cm.
Working Procedure: (M Size T-shirt).
At first, take a rectangle whose width is half of ½ chest and length is front & back length, where half of ½ chest is around 26 cm & the front length is approximately 70 cm, and the back Length = 68.5.
Secondly, take front neck drop & back neck drop 2 & 11.5 cm from HPS.
Later, half neckwidth is taken where half neck width is about 10 cm.
Then, take the shoulder width of 12.5
Then, grab the shoulder slop 3 cm from HPS.
After that, take an armhole depth of 23 cm.
Then, take ½ waist 24 cm and half of ½ waist 24.5 cm from HPS to bottom.
After that, Separate the front & back Parts and cut the front & back parts for Pattern making.
Then, make the front and back parts pattern symmetrical.
Then prepare the neck which length is 52 cm and width is 4 cm.
Sleeve Preparation –
At first, take the rectangle which length is 21.5 cm and width is 20.5 cm
Then, take a Sleeve Cap height of 12 cm.
After that make the Curve.
Then take the sleeve hem 17 cm.
Mirror the half sleeve.
Cut the sleeve for Pattern.
