Using with ArcCateLog tools convert the cad dwg file into shap file.

Now we can know the longitude and latitude of ten points on the cad dwg file,how to set the coordinate of shap file?
We should publish the shap file data as restful webservice.

 

I use Arc MAP 10.4.1 and Arc Server 10.4.1.
We can know the longitude and latitude of ten points on the cad dwg file,is that say we know about real coordinates?
But,how we can get a real projection system use the ten points on the cad dwg file?
Is there some examples to reference????

 

1.The shp file which is converted from cad file.
2.The png file with ten points on which is printed from cad file.The longitude and latitude is signed by hand on the png with Photoshop.
Can we use the map matching tools?
Using png file to match shp file,is it feasible?

 

Can I sign the longitude and latitude of ten points to dwg file directly???
Whether the shapefile will carry with the longitude and latitude when convert from dwg file???
Whether it need install plug-in for autoCAD in order to sign the longitude and latitude of ten points to dwg file directly.

I just have a cad dwg file and a txt text file.
In the text file has recorded longitude and latitude of ten points which have signed on the dwg file.

In a word ,the fundamental goal is set  longitude and latitude on shapefile with known ten geography points.
