Door Jamb

Hi there,

 

I'm a somewhat newbie user, and am drafting up a door from LL Eric Wing's Architectural Families course. It calls for starting with modifying the door opening and then inserting a jamb sweep. I thought I followed the steps- entered reference planes for jamb width, shim, stop, etc and locked the profile to those reference lines. The profile sweeps beautifully. If I try to change the size of the door opening, the jamb doesn't move with it. Either have to break constraints or get error messages. Does anyone know why the reference planes aren't moving with the changed opening size?

 

Option A- if break constraints

Option B- error without breaking constraints

Thank you!

Place dimension between the left and right ref planes and assign Width
parameter. Also, place a EQ EQ string from left to center to right planes.

Hi ToanDN, Thank you for responding. The family has those parameters already. I just uploaded the file. Maybe the jamb references planes aren't tied into the door opening parameters somehow?

Try this one. I created the profile using a family, not sketch.

FYI: Your Sweep is not "tied" to any Ref. Planes. Sweeps use 3D Paths only.  RPs are 2D. Your Sweep Path is following the Opening Cut.

Does it make sense to you why the jamb doesn't flex to follow the changed opening cut when I change the door size?

The Sweep Path flexes fine and dandy. It was the Sketch-Based Profile that couldn't follow the Path. I didn't investigate why. I just recreated the Profile in a Profile Template Family and used that one in place of the Sketched Profile.  Maybe it could work as a Sketch if you dimension and lock the Sketch linework.  That'll be a chore though because of the tiny corner fillets.

If you took a look might you be able to see what happened? I did create locked reference planes with labeled dimensions/parameters the way I thought the video recommended but just created a second model and the same constraint problem is happening. Maybe the profile lines should be locked to the reference plans and aren't? This is less about having something that works than understanding the why. No worries if you don't want to take a look...

So I'm following the step-by-step instructions from this course and able to sweep the sketch profile. When I 'flex' the family to test it, and change the door height from 7' to 8' that works no problem. When I try to flex from 3' to 4' width, it won't do it, and I now get this error message... I don't understand how this message helps me...

 

Thank you!

The sweep in the family you posted was following a 3D Path.  Are you saying you sketched a 2D Path?

The path of the sweep was the edge of the door in elevation (arched top)- just 2d

If you want to troubleshoot, try sketching a simple rectangular profile and see if that works. Betcha it does. And if it does, then you've narrowed it down to the Profile you originally sketched as being the main issue. Keep in mind that Revit can't compute very small line segments too well.  Less than 1/32" and behavior is unpredictable.

Let's see that tutorial you are following. Post screenshots of it here.

Ah- thank you so much for this. So it wasn't the profile- I tried plain rectangle and it also didn't work. The video (about 3 videos- a lot to screen shot) calls for reference lines with labeled, parametric dimensions for jamb shim, jamb width, stop width, etc. I erased those and redid them- still didn't flex. Then locked them- that seems to have made the difference. Now I'll check to see if the video either asked for that and I missed it, or simply did it and I missed it. Anyway- it works, thanks to your guidance. Thanks very much-

Dang, that wasn't it! Just unlocked the dimensions and it still works. Its fixed by redoing the profile reference plane dims and profile itself but I don't know why....

Examine the attached revision of your original file.  

 

Let me impart a little advice to you:  Do not bury Reference Planes and Labeled Dimensions inside Sketch Mode.  By "Labeled Dimensions", I mean those Dimensions that are driven by Parameters.   When you put Reference Planes and Labeled Dimensions inside Sketch Mode, you can't see them outside of Sketch Mode. This makes it doubly difficult to troubleshoot.  Instead, place all your Ref. Planes and pull all your Labeled Dimensions between Ref. Planes in the "main" view. Think of it as building the framework first.  Then, when you enter Sketch Mode to create a Sweep or Extrusion or whatever, align and lock the sketch linework to the existing Ref. Planes (e.g. the "framework").

Interesting, thank you!
