    confusion while constraining model text

    I'm trying to create a compact parking stall with a painted "C" in the center. I want the stall to have instance based width and length parameters, and the C needs to be centered in the stall and aligned with the front. Here is my process and I think I haven't broken any rules:
    1. Place a reference plane centered between the stripes. Flex to confirm the reference plane moves appropriately.
    2. Align and lock the bottom of a model text "C" to the front of stall reference plan. Flex to confirm the "C" moves.
    3. Align and lock the center of the "C" to the center of stall reference plane. Flexing results in the message "Constraints are not satisfied".
    4. Delete the model text and paste aligned to current view (to remove constraints). Align and lock the center of the "C" with the center of stall reference plane. Flex to make sure the "C" moves.
    5. Align and lock the bottom of the "C" with the front of the stall. Flexing results in the message "Constraints are not satisfied" again.

    I am lost again (again). Any suggestions to what else I should be doing? I've attached the family for reference.

    Bonus question: I started with the OOTB parking stall. Why are there invisible symbolic lines in the plan view?

    I'm guessing model text would work the same as regular text....

    Place a reference plane(s) where the text is constrained from....(like center middle)...Group the reference planes and text....then align and lock the reference planes to where you want them in the family...

    The invisible lines help with alignment....

      OK, I grouped the model text and reference line. This seems to have solved my issue -- thanks! However, I'm still confused about why I need to do this and how it resolves my issue.

      I'm also curious why you mention model text possibly working the same as regular text? Creating this family is my first exposure to model text, and I was pleasantly surprised to find I could align the text center, bottom, left edge, etc., very much unlike regular text (to my Autocad brain's dismay). Is there some trick to aligning regular text to a reference plane before grouping them for another purpose?

      And regarding the invisible lines: sorry for the STOOPID question but do you mean aligning stalls while placing them?

        Have you tried to created a nested model text family using Face Based template? I did it all the time with this trick since the nested text can be locked once it is nested to the host family (parking space).You can also set all the parameters like text size, depth, and more from the nested text and carry over to the host family.

          Thanks for posting. I have not. Michael's suggestion resolved my issue (being a NOOB, I'm not sure how though), and I moved on. It sounds like your suggestion provides more control for different variables. I'll try it the next time I come across a similar situation.

            Update

            I came back to review this thread while trying to fix an exit sign (the model text was not moving with the rest of the geometry). This is a two-sided sign, and the model text on one side WOULD NOT stay with the rest of the geometry despite applying many different versions of Michael's grouping sequence. I used the Parametric Snowman's tip of nesting a model text family into the sign family, aligning and locking to reference planes, no grouping needed. This has fixed the family.

            So, both ways have worked for me at different times. As a NOOB, I wish I understood what caused the first method to break down during my second exercise.

              Thank you for this insight! In MEP I have unistrut that will vary in length (instance) and I fought for hours to get model text to stay at the end that moves.
