Dion Moult Revit is shit. Revit is a proprietary software developed by the monopoly Autodesk for the AEC industry. I speak from the where to purchase Revit 2015 software of an architect working on large commercial projects across different building typologies, and therefore do not use the MEP aspects, which may be better than I have experienced here. I have a background in software developmentpreviously working as a software architect.
Software architects deal with many of the same issues as BIM data where to purchase Revit 2015 software. There are ever-changing client requirements, lots of small pieces that interact, and domino effects of changing the design in one area. I have where to purchase Revit 2015 software used a great deal of software on many platforms, including 3D modeling as practiced by the CG industry, point clouds, programmatic typesetting with Lilypond and LaTeX, and am also closely following OpenBIM initiatives.
With this background, I hope to present a fair but critical list of issues I have faced with Revit. Revit does not know what a building is Revit has failed to implement even the most basic of BIM concepts: You can categorise walls, floors, roofs … but a building? If you have two buildings next to each other, Revit has no way of saying that some walls belong to building A, and some belong to building B.
No way of categorising a shape to represent a building or that some levels are part of building A and some are part of building B. Have a shared site with mix-use buildings where two buildings merge? In contrast, the first thing that you do when you launch FreeCAD to create a BIM project is to define a building with storeys in that building that belong to a site.
Will your roofs become IfcRoof, or will Revit decide your roof is a slab instead? Will your windows become IfcWindow? Who knows.
Revit does what it wants. Will your building element turn up at all? Will it even export? Will it import? Ah, the mysteries of the universe. The simplest IFC of a few kB will take 15 seconds to import and in the process Revit will multiply the filesize by at least Revit will develop a mapping and create a special Revit file just to where to purchase Revit 2015 software and perform the most rudimentary filtering on the IFC file.
This creates issues with round-tripping, consultants using our files, and even ourselves trying to use our own files. It also forces where to purchase Revit 2015 software to expose company intellectual property if we send out Revit files. I am aware of being able to patch the IFC export type during the export process, and the IFC mapping where to purchase Revit 2015 software within Revit itself, as well as the special Ifc override properties, but I should not need to hook into the export process and the mapping process is not reliable.
In most cases, such as in system families, you simply cannot change the mapping. There are 35 or so reasons why a building element will not show on your view The predicate determining whether or not a building element will be visible in your current view depends on at least 35 different settings.
In fact, in their help file they identify certain extremely nefarious ways that can hide things and condone where to purchase Revit 2015 software firing of any co-worker who commits such a sin. They have also started a Revit object invisibility hall of fame. You cannot set a datum level on a sloped roof Create a roof by footprint. Set it at a certain level. Now if you add a slope to the roof, what RL will the roof edge be at?
The answer is nobody knows. Revit will decide to pivot the roof wherever it wants and your edge will be a shitty RL that the builder will ignore. The datum level of where a ceiling slopes is arbitrarily defined If you create where to purchase Revit 2015 software rectangular ceiling sketch at a particular level, define a slope going from one edge to another. Which edge will stay at the original level, and which edge will slope up or down?
So in practice, you have no idea where your ceiling is going to slope, and you need to move it around by trial and error. This is still broken even if you explicitly draw a slope arrow and say that the head or tail is where to purchase Revit 2015 software a specific level. Revit will totally ignore whatever value you put there and do whatever it wants. Revit knows best. The only solution is to redraw your ceiling or rotate the entire ceiling.
Wall types and joining walls is a nightmare Before I complain about this one, I would state that walls and joints are a very hard problem. Walls are layered, and has many rules on what takes precedence in a joint, both in a plan and in a section, and Autodesk has made an attempt to cater for this.
Unfortunately in practice, we have walls which are too eager to intelligently snap, walls in groups who must be unjoined to prevent Revit errors, the inability to dimension to the core of a wall which is how people build walls, go figurecurved walls and sharp angles in funky facades that encounter strange junctions, and so on. According to the IFC definition and to common sensea lining on a furring channel, and a block wall should be 1 wall, not 2.
The fundamental problem is that Revit has only implemented three types of walls: Notably missing is where to purchase Revit 2015 software IfcElementedCaseWall, for scenarios where walls are made up of different elements like studs, channels, insulation, and lining but are assembled together into a single wall.
If Revit allowed you to define walls as a sum of parts, it would where to purchase Revit 2015 software more flexible and still semantically correct. Revit also does not implement things that are purely cladding i. This means that people draw bump rails, skirting, and moulding as railings or walls, draw slab insulation as floors, and of course, draw cladding as walls.
Where to purchase Revit 2015 software is wrong. They have different joining rules, and things like fire, acoustics, and thermal apply differently. They are a different cost item. Yet they are all lumped in the same basket.
No OOTB align and distribute functions for any type of annotation or anything, really Are you tagging an elevation? Will any of your tags line up horizontally or vertically? Will any of your tags be equally spaced between grids or building elements? No, of course not. Revit hates you and wants you to eyeball all your annotation positions. Except, strangely, when you use a leader in your tags. But not to fear! There is a free addon which will allow you to align objects called BIMAlign.
This is good. In practice, however, CAD links do not work reliably. From the inability to share coordinates, having missing geometry, lagging of the Revit file, hatch patterns going haywire, and geometry out of extents errors. These problems do not exhibit themselves in simple vanilla CAD files, but are very common in complex projects. This means CAD files have to undergo a cleanup process where we purge, delete, explode, and sometimes copy and paste into a blank file to start again.
Instead, you can draw lines manually. That is, unless you create a fake table and put data in the header. From a reader comment, I should note that it is possible to overcome this with various Revit plugins that allow you to link data from spreadsheets.
In-place doors are not room bounding, whereas family doors are A family-created, wall-hosted door does not change the room bounding property of its host wall.
An in-place door, will not. This is in contrast to the IFC specification which explicitly explains about the scenario of doors in where to purchase Revit 2015 software The wall represents a vertical construction that bounds or subdivides spaces.
A wall may have openings, such as wall openings, openings used for windows or doors, or niches and recesses. You cannot draw a slanted wall In Revit world, all walls are completely vertical. Modeling anything where to purchase Revit 2015 software complex than that requires proxy construction objects. This is even if you disable the scope box. It only starts working as expected if you uncheck the include checkbox, manually fix the north orientation setting, then re-check the checkbox.
Go figure. Revit has incorrect or incomplete classification systems Did you ever want to specify an Omniclass specification for an object?
Revit is especially harsh towards IFC classifications, and in fact makes it completely invisible in the interface, but has a separately documented feature where certain shared parameters have magic effects on IFC classifications. So without knowing exactly what you type, your IFC classifications could well be nonsense. No backwards compatibility without a good reason for doing so Yeah. Autodesk wants you to buy the latest version. All the time. If you accidentally open a file with a newer where to purchase Revit 2015 software, it will upgrade, and if you forget to do a save-as, you have now irreversibly broken the compatibility with an older version, and so assets shared within the company where to purchase Revit 2015 software cannot be used on older projects.
A single border style in a schedule is uneditable when a view template is applied Are you feeling creative? Have you changed the line style of a single border in a schedule?
Once you apply a view template, you will have no way of editing that single border anywhere, unless you disable your view template. Revit does not know what a block wall is The number one waste in the construction industry as measured by weight which is the preferred metric for the waste industry is masonry.
This is unsurprising as Revit where to purchase Revit 2015 software not know what a block wall is. Your best bet is to create a hatch pattern using the archaic pattern syntax, of which people have built generators for it online because it is so unintuitive and align it on the surface. Revit does not lock to eye level, or any level, during first-person perspective camera views Revit does have support for a first-person view and movement using the camera view, despite the Revit 3D viewport renderer being extremely inefficient this means while moving you will experience lag, flickering, and incorrect rendering.
Unfortunately, it has no way to lock to a certain level. This means you cannot consistently guarantee an experience of your design at eye-level, and will be always floating around randomly. Falls break the alignment of hatch patterns This is not the same issue as the hatch distortion above, but it is similar.
