When you open up new AutoCAD drawing you might prompt with this dialog box;
To skip this dialog box and tell AutoCAD to open specific template automatically, you can do it with this steps;
1. Click New
2. Open acadlt.dwt (or other template file)
3. Right click at drawing, Click Option.
4. Expand Template Settings>Default Template File Name. Click None and click browse.
5. Select your AutoCAD template file (mine is acadlt-with-layer.dwt), click Open.
6. Click Apply, click OK.
By setting up this option, next time you click for New Drawing AutoCAD will open this custom template automatically and make your life a bit easier.
I recommend you to include your preset layer in this template too. So you don’t have to recreate your basic layers every time.
