1.Create a dimension

2.make BLOCK with the dimension,transform with rotate ,move ,non-uniform scale

3.change the dim style

4.if you explode the INSERT,the dim will change.so i find way to get the subentities of the dim and transform it to Model space

i have found that the dim is similar to anonymous block which name "*D".

and my method is nentsel to get the matrix M1.

and i can get the INSERT matrix M2 with refgeom.

so the dim matrix M3=(inverse M2)*M1.

that is my way.

now,i want to get the dim matrix M3 without nentsel/nentselp,how can i do?

the ranslates matrix is dimension's dxf 12
