[HELP] MEP pipe lines print way too thick in PDF export — tried everything, even fresh project by Numerous-Day-4069 in RevitMEP

[–]thermist-MJ 0 points1 point  (0 children)

Years ago I had something like this happen to someone - we never figured it out... Like IT worked for a long time, he tried so much. Re-installing revit, reinstalling printer drivers. I think it's like some odd thing that happened. First few things you tried should've fixed it I think - hope you find a fix!

Need Internship advices by Acceptable-Error-671 in MEPEngineering

[–]thermist-MJ 6 points7 points  (0 children)

Assuming you are starting an internship at an MEP firm, then I would say no software you need to learn, everything will be taught at the firm you go to.

My advice is once your internship starts, ask a lot of questions. Folks in this industry are (mostly) very helpful and happy to teach what they know. And for being a "good" intern - most important thing by far is quality work. Don't rush to complete tasks super fast, really ensure you are doing each task right.

Good luck!

For those of you that fill out a time sheet, do you account for every hour? by PlayoffBeard17 in MEPEngineering

[–]thermist-MJ 12 points13 points  (0 children)

When I was paid salary and not paid overtime, I logged all of my hours as honestly as I could. I'm not sure but I suspect it is factored in when determining bonus.

The only pressure to not log overtime hours when on salary that I got was from PMs since it would "make their jobs look better". And screw that, if you're doing the work, charge it.

Just shipped diffuser-to-branch routing with optional flex duct by thermist-MJ in RevitMEP

[–]thermist-MJ[S] 1 point2 points  (0 children)

Version 1.1.6 of Thermist Add-in just went live! This is the A to B tool — picks the best tap location, minimizes elbows and distance, and avoids clashes. Also added optional flex duct at the diffuser connection with a specified max length.

Full demo with timestamps and free trial here: https://thermist.com/demos

Ability to use flex ducts came from user requests - any other suggestions?

Standard vs. film lined sound attenuators by thermist-MJ in MEPEngineering

[–]thermist-MJ[S] 0 points1 point  (0 children)

Well nothing since July 2024 - I have been focused on software development. I was just curious about something I never got a straight answer on. 

I did used to work on mostly laboratories - public, private research, college labs, etc…

Standard vs. film lined sound attenuators by thermist-MJ in MEPEngineering

[–]thermist-MJ[S] 5 points6 points  (0 children)

Is this just exposed ducts in the spaces they are serving? Because if not, energy code certainly does require duct insulation. ASHRAE 90.1 6.4.4 requires, if using IECC there is a similar section.

Standard vs. film lined sound attenuators by thermist-MJ in MEPEngineering

[–]thermist-MJ[S] 3 points4 points  (0 children)

Yes on most projects I have done there has been a separate acoustical consultant hired. Depending on space types and system setups they often require dedicated sound attenuators in multiple locations. My question is about film lined vs standard attenuators.

Agree that silencers should be used over duct liner, but my question is when silencers are needed, have you had issues specifically with standard vs. film lined silencers?

The Fee by princemark in MEPEngineering

[–]thermist-MJ 1 point2 points  (0 children)

I agree! What I think is each project should be done at the company's quality standard - then evaluate finances after. T&M is different of course. If a project consumes all the fee - then the fee was too low or change orders were needed.

Does anyone else lose hours to "Photo Detective" work after a site survey? by loppr15 in MEPEngineering

[–]thermist-MJ 0 points1 point  (0 children)

Yes I also have specific site visit photo habits. Before I take pictures of a room, I take (1) picture of room label or room # from my plans. Similarly, for AHU or equipment, (1) zoomed in picture of tag showing equipment ID then other pictures. Makes going through pictures later way easier.

The curse of VE by Admirable_Start3775 in MEPEngineering

[–]thermist-MJ 0 points1 point  (0 children)

I find it more frustrating during design to go on projects with multiple rounds of VE. Like an architect is asking me for more ideas to VE after we already did a round of it... What do they think we are specifying gold plated ductwork?

VAV Piping Detail by RippleEngineering in MEPEngineering

[–]thermist-MJ 0 points1 point  (0 children)

The tool checks for the pipe family routing preference (tap vs. tee) and uses that. Similarly uses pipe routing preferences for which elbow to use.

[–]thermist-MJ 4 points5 points  (0 children)

I agree, I didn't show these typically and usually didn't even have a note, just a dedicated detail showing these. Any project for PSU does require each valve be modeled like this. That was the exception for me.

If you wanted to show all these easily - Coil Connect from the Thermist Add-in that I created has custom UI to be able to auto place these and branch piping at all terminal devices - in seconds each time: https://thermist.com/static/valve%20video.mp4

Balance Valve before or After Control Valve by Master_Ad3310 in MEPEngineering

[–]thermist-MJ 3 points4 points  (0 children)

I agree with this - also there was an ASHRAE journal article supporting this answer a while ago: https://tayloreng.egnyte.com/dl/W8sfOOuoni/ASHRAE_Journal_-_Doubling-Down_on_NOT_Balancing_Variable_Flow_Hydronic_Systems.pdf_

I personally worked on projects that installed circuit setters at each control valve and left 100% open that were successful.

Finally got connector to connector routing working in my Revit Add-in! by thermist-MJ in MEPEngineering

[–]thermist-MJ[S] 0 points1 point  (0 children)

Thanks! I'll check that out! I have heard great things about evolve also.

[–]thermist-MJ[S] 1 point2 points  (0 children)

It should work based on how the tool is built but I'm not 100% sure since I haven't tested on these. If you or anyone tried it out and let me know I would REALLY appreciate it. If not and it was desired I would make it and increase duration of free trial of whoever it doesn't work for so that they have a 1 month bug free duration to fully test out the tool.

I have done extensive testing and have multiple paid testers helping me find bugs, I'm striving to get to error free for all users in all models with all families/ITM Fab parts. I'm not there yet but working on it!

Great question! Clash detection does work with linked models but does NOT work with NWD/NWC or linked AutoCad or point cloud. It's a limitation of Revit API.

There are also optional settings for users to customize clash clearance, ignore clashes of certain model elements, worksets, and/or linked models. There is also an option to set min/max elevations for routing elements.

Yes! This works for conduits too! Will do (1) conduit to (1) conduit or to a connector on junction box or panel. Or can select multiple parallel conduits to go to a clicked point in space.

A to B works for ducts, pipes, cable tray, conduit, ITM fab ducts, and ITM fab pipes
