Closing Loops, in place components

Creating In place component ( a tapered plate) using projected geometry in a assembly with INV5. Usally to close a loop I pick one line RMB, close loop, then pick the other lines and the loop is closed. This never works when in a assembly no matter how the selection priority is set it does not allow picking the other lines. I can't find this addressed in other posts.

Creating in place components like above always seems to be a trial and error process, sometimes drawing over the proj geometry works before you extrude.

If the part needs to be adaptive then the "enable associative edge loop geometry during in place modeling" tool must be on. Right?

If that setting is off you can hold the control key when projecting and it
turns it on for that one projection. Also if you make a non adaptive
feature it can later be made adaptive by right clicking on it in the browser
and turning on adaptivity, and then using 3d constraints to control what it
is tied to.

You cannot use "close loop" because projected geometry is "reference"
geometry.

You would have to select the projected geometry (window select) and turn
it into "normal" geometry via the style pulldown.

At this point, your geometry can be marked adaptive and can be
controlled with assembly constraints if so desired.

CPA (Cross Part Adaptivity) (what you refer to as "enable
associative......") should basically be avoided unless you specifically
can draw upon experience and make an informed design decision to use it.
CPA does more than just create (associative) faces from other parts; it
actually defines the position of projected geometry and will render
"normal" adaptivity useless and cause model failures 99% of the time.
There are a few other considerations like re-defining faces and trying
to use CPA across sub-assemblies that will also throw the unsuspecting
user into a state of confusion.

Than You for responding to my questions. Changing the proj lines to normal lines at least lets you move on and allows the use of a profile for extruding.

It should have been stated as two questions. The first question was a selection question when trying to close a loop of normal lines, not reference lines. Its possible the projected ref lines are messing up the selection process, but I even tried closing a loop on a sketch plane (ie only in a assembly iam.drwg) with all the projected geometry deleted. Pick line, rmb,close loop, and the it wont allow seleting the second line, allthough it will pick other lines in the asembly that are not even on the sketch plane. The same procees works fine in a part drwg.

Changing the ref lines to normal lines, deleting the problem lines and drawing new lines on the end points
gets a profile that can be extruded, but I still cant close the loop. It seems that in some cases projected geometry should not be used.

From reading the posts, some people chg the ref lines to normal lines and others draw regular lines over the ref lines and use constrain lines to be colinear (it does not seem to like pts) to get a working profile for extruding.
