I am trying to create a loft surface using the 4 entities 3dsketch 14, 15 (profile curves), 16 and 19 (constraint curves). However, I am unable to select the entities 14 and 19, even though it is a completely continuous entity. Can some one help me understand as to why I am unable to select these entities (14 and 19)? I am sure there is a work around to create a surface using the four boundary curves of the front surface. Can someone help me with the work around for the same?
The part is available here.
