Autocad Mep 2013 Hangers For Sweaters
.Applies to: - Revit MEP New Feature / Problem: Create supports, hangers, and bracing for pipes, ducts, conduit, and cable tray. Sometimes multiple objects are hung from from a vertical stacking of single hangers or racks, so this also needs to be a cability. It is important for these objects to be able to conect to the objects they are suppporting in order to grab the intelligence of those objects and display it in scedules.
It would also be helpful to have floor mounted supports (concrete and steel) and steel racks. Of enormous help would be the ability to have the hanger read the weights of the objects being supported. The engineers can then determine the proper size hangers/supports.We repeatedly touched on various topics related to the Revit MEP API.
Here is another little item that is a bit more out of the way, some information on.Why do you need this Feature / Why is it a Problem: MEP contractors need to be able to prepare construction documents (and perform clash detections) with these hangers, supports, and bracings. Without these, the VDC model is incomplete, and still more work needs to be done in AutoCAD, or the entire job gets done in AutoCAD. Not having this feature inside Revit is keeping many contractors from seeing Revit as an alternative to AutoCAD MEP. Workflow: AFter pipes, ducts, conduits or cable tray are routed, the hanger would be an object to be added to these entities, that would assimilate the intelligence of those 'parent' objects. In the case of multiple objects on a single rack, the rack would inherit intelligence from all objects. Annotation of the supports and racks could be similar to that in AutoCAD MEP. Schedules, and alternative tags should list which objects are in the support.h21h21h21h21h21h21h21h21h2 1Benefits: Reduced time in design of construction documents by contractors.
No need to duplicate efforts when the job requires a deliverable in Revit and the designer must do the hangers and supports in AutoCAD MEP (or other ad-on).We have jobs coming up that require a Revit deliverable, the AE firms have delivered a mostly usable set of Revit files, but we cannot do our work in Revit. We are anticipating having to possibly rebuild everything in AutoCAD MEP to do our work, then perhaps do an IFC export, bu that involves a dramatic increase in file size, and the filse sizes are already each in the neighborhood of 500mb. Attachment comments: Do you agree with the above??Use the ' RATE THIS THREAD' tool at the top right corner to express you opinion.You can add hangers to ducts, pipes, cable trays, and conduits. You cannot add hangers to fittings. When you add a hanger, the midpoint of the hanger top is positioned relative to the midpoint of the bottom of the building system object to which it is anchored. Because the hanger is anchored to the object, when the object moves, the hanger moves with it. When the object is deleted, the hanger is also deleted.
To add hangers.Start the add command by doing one of the following. Open the Tools palette, and click the Add Hanger Support tool, if available. On the command line, enter HANGERADD. If you want to add. A single hanger for Insertion, select Single.
Hangers at a specific distance interval do the following.For Insertion, select Along Run. For Distance between, enter the distance between the centers of the hangers. A specific number of hangers at a specific distance interval do the following.For Insertion, select Along Run (Fixed Number). For Distance between, enter the distance between the centers of the hangers. For Quantity, enter the number of hangers to insert. In the drawing, select the building systems object to which to add the hangers.
Click to specify the location of the first hanger. If, for Insertion, you selected Along Run or Along Run (Fixed Number), click in the direction you want to place the remaining hangers.supernalarmor.
Has a new hanger / support system been incorporated into v2013?The current (UK) hanger system has several negatives:. When modifying pipe (adding fittings/branches, size changes.), hangers uncontrollably relocate along a pipe. Rods only have option for length, in lieu of a set height (setting a specific elevation.e.g. 15'-0' for the bottom of a deck). Also, no ability to extend accurately to a sloping deck. Sloping pipe: Hanger rods aren't vertical when placed on sloping pipe. Locations are imprecise for field install.

Scheduling / material takeoffs are wrong, due to inability to set rods to proper height.

To keep your hangers from moving when modifying pipe, just lock the layer that the hangers reside on.
This will keep them from moving.2. Rods definately have the ability to extend to a sloping deck. You just need to know the elevation of the deck where the rod will connect. You already know the elevation of the bottom of pipe and now you know the elevation of the bottom of the deck.
Subtract the bottom of pipe from the bottom of the deck and you will get the length of your rods. Modify the length in the property palette and you are good to go.3. Yes the hangers do slope when connected to a sloping object. If you have your hangers set to display in a plan view when in a top down view, the rods do not show up as sloped. I mark my locations using this view.
For my procedures, i do not need an elevation assigned to this location as the installer knows its the bottom of the deck. He just needs to know a x and y location.4.
See the answer to number 2. Is it a pain in the butt to set the length.yes.but it is possible to do. So yes they can be scheduled with a correct length.
Dont forget to add your rod overrun to the rod length and the amount that you will be inserting into the deck. Total rod length = length + overrun + insertion depth,Bottom line, the hangers can definately be improved but you can do everything that you need to do with them. It is just not as easy as it could be.
Thank you for the informative reply.It definitely is a pain to maintain the hanger location and make accurate takeoffs, especially for prefab. One of our objectives is a clash free model.which means we are adjusting piping and also hangers for coordination. If we change an elevation of pipe, then we must also adjust the support height of the hanger rod. This can be a very tedious task that adds time and increases errors when making takeoffs for prefab. The current hanger system is just not time efficient to adjust 1000s of hangers (accurately).We've tried locking the hanger layer, without success. Locking the layer appears to keep the hangers in place, and appears to work, but when MEP regen (objrelupdate) is applied after hangers are unlocked, the hangers will still relocate. I attempted this procedure on a project by marking all of the hanger locations with a circle (to verify they moved).Another 'negative' on this tool is upsidedown hangers.

Many extra clicks are used to rotate hangers to a positive Z. The hangers insert based on the rotation of the pipe, which varies depending on how it was drawn.
