How to show Radius Dimension in Drawing fusion

[cn50003]

Hello everyone,
I am having a problem when designing, I created a solid with the same size as the sketch above, but when I create a 2d drawing in the drawing environment, I cannot drag the arc dimensions as the sketch shows,hope everyone give instructions!!
Thank you.

if you split the face in the model at locations where you want a dimension, it will provide you with points in the drawing environment you can use for dimensioning.

Hi! Without seeing the actual drawing, I can only speculate. I guess the target view edge (silhouette) is a spline, not an arc. You may want to make the model sketch visible in the drawing. Then you will be able to dimension to the sketch in the drawing.

Many thanks!
