Merge wall footings with adjacent footings without lines at joints?

[denisef]

I have two related issues that I need advice on.  Merging of footings.

1.  When placing a wall footing along a wall with openings, I always get a break in the footings at the openings when first placed. See wall before footing below:

Wall with footing below, footing breaks at openings when footing first placed:

Wall with footing dragged "closed" at openings.  "joint" line remains.  

THIS IS MY MAIN QUESTION:  How do I remove these "joint" lines?

2.  Similar question, but the joint is happening with an adjacent footing, wall & spread, and the joint line is not going away, although at the other adjacent joint the lines went away.  One is a wall footing, and one is a spread footing, again, same situation adjacent and it worked.  All footings on same elevation and same depth.  See clip below:

Any advice is greatly apprecitated.

Sorry for the wordy title! "How to merge footings in Revit?" that's what I should have titled it! 🙂

as far as your footings go.... are they at different elevations or thicknesses? if they are not perfectly even, you will see that after a join. 

have you tried using the Linework tool to set those lines to <Invisible Lines>?

[denisef]

yes, the footings are all at the same elevations and thickness.

I have not used the Linework tool, I will try that option and see if anything improves.

Thank you

another thing that can cause that issue is if the Material is different in both elements....

[denisef]

thank you for that insight. I will also check the materials.

See the snap below to provide more light for wall footing queries. Wall Footing can be drawn as separate walls as you did, and if both are the same elevation, then the footing can be dragged and merged as stated in the early response by J Howard Munsell.

If the wall edit opening is drawn from the bottom, then the footing wall is shown above as per pics. The door opening has no problem with wall footing placement for line or joining. I have given here all situation-opening scenarios for your reference.

I hope this will helpful to understand the fact in detail.
