How to edit MEP ductwork?

[near4321]

Hi,

I'm completely new to Archicad, I'm using 26 and just would like to learn it.

I'd like to draw a simple duct system using the MEP modeling tools, and although I can use the MEP route planner to "start routing" and "finish routing", my problem is how do I edit those ducts afterwards? When I try to select a node to move it always selects the whole thing. Even when I ungroup the pipe, then I just select a segment, but won't be able to adjust the nodes within that segment.

I tried to follow this: https://help.graphisoft.com/AC/28/INT/_AC28_Help/085_MEPDesigner/085_MEPDesigner-1.htm

But nothing seems to work like this article describes.

I applied the MEP profile as described by the help page above: Options > Work Environment > Apply Profile > MEP Engineering Profile

It didn't help.

When I select those pipes what I created with the routing dialog ( "start routing" / "finish routing"), I don't see any of those actions (move node, insert new node) in the hovering toolbar. So for example, I don't see this, only the actions in the line below it:

Also, the Enter System edit mode menu is disabled.

Clearly I'm doing something wrong. What do I do wrong?

Thank you so much!

You say you are using version 26 but the link you give is for MEP in version 28.

The MEP system was changed in 27 and amended further in 28, so it will have few similarities with 26.

Many say 26 was better, but we won't go there!

Here is a link to the MEP section of the reference guide in 26.

You may also find some videos on the Archicad youtube channel ... https://www.youtube.com/@Archicad/search?query=MEP

I am not sure if there are any specific to version 26, you will have to do a bit of searching.

You be looking for videos posted about 3 years ago.

Hello BARRY, the problem is in the documentation of quantities, where the 90 elbow joins the 45 elbow, and I want to know each one separately. Is there a solution for this?

[Barry Kelly]

I can't really help you as I don't use the MEP tools, so am not familiar with them.

You will need to specifically look for help for version 26 MEP.

The MEP systems changed in 27 & 28, so the latest help may not be of any use.

Have you read this in the help guides?

Unfortunately, the MEP in AC26 was excellent and we needed simple additions. Now in AC28 it has become restricted. You cannot fill elements or create multiple labels and properties, and it also does not accept stretching...

[Barry Kelly]

So, your first post, you said you are using version 26.

Are you looking for help with MEP in 26 or 28?

Some say 28 MEP is not as good as 26 although I am pretty sure you can still stretch things.

I need help with AC28. How do I know the number of 45° and 90° elbows and determine the ID for each element?
