There are any number of reasons thicken fails.</P><P></P><P>With the boundary blend, you can control the tangency. In this case, making the two ends Normal should suffice.</P></BODY></HTML> Tue, 11 Jun 2013 14:40:34 GMT https://www.ptcusercommunity.com/t5/3D-Part-Assembly-Design/How-to-connect-the-two-surfaces-smoothly/m-p/71269#M56046 TomD.inPDX 2013-06-11T14:40:34Z Re: How to connect the two surfaces smoothly https://www.ptcusercommunity.com/t5/3D-Part-Assembly-Design/How-to-connect-the-two-surfaces-smoothly/m-p/71270#M56047 <HTML><HEAD></HEAD><BODY><P>Normal?What do you mean?I want to make the connecting boundary of the surfaces as smoothly as possible.</P></BODY></HTML> Tue, 11 Jun 2013 16:13:15 GMT https://www.ptcusercommunity.com/t5/3D-Part-Assembly-Design/How-to-connect-the-two-surfaces-smoothly/m-p/71270#M56047 ptc-5110245 2013-06-11T16:13:15Z Re: How to connect the two surfaces smoothly https://www.ptcusercommunity.com/t5/3D-Part-Assembly-Design/How-to-connect-the-two-surfaces-smoothly/m-p/71271#M56048 <HTML><HEAD></HEAD><BODY><P>Yes, and if the end of the "tube" is "normal" to the plane of the circle, then you want to continue the surface "normal" to the circle. You could try to see if the boundary blend will go tangent to the previous surface.</P><P></P><P>You have to think about what I am saying here... tangent and normal are have a really close relationship when put in proper context. </P></BODY></HTML> Tue, 11 Jun 2013 16:28:51 GMT https://www.ptcusercommunity.com/t5/3D-Part-Assembly-Design/How-to-connect-the-two-surfaces-smoothly/m-p/71271#M56048 TomD.inPDX 2013-06-11T16:28:51Z
