All you need is a SOLIDWORKS ID, or a new or existing 3DEXPERIENCE ID.
The drop down to switch between press or clearance dowel should be changed back like 2018. You have to press arrow at bottom for tol/precision, then press the tol none button, then choose fit, then push user define button, then finally you can choose press or clearance. Very user unfriendly.
