4. OSTEC-REVIT includes families of the OSTEC cable support system and the “OSTEC – Cable Routes” application, which allows:

• place trays depending on the installation method (wall, floor, ceiling);
• automatically place elements of the mounting system (suspensions, consoles, racks) at user-specified intervals;
• place tray connectors depending on the selected connector type and the type of trays at intervals equal to the length of the selected tray type;
• export a list of cable trays and components in XLS, XLSX (Microsoft Excel) formats.

For detailed information on installing the application, project template, and families, see the User Guide. Features of designing an OSTEC cable support system in the Autodesk Revit environment are presented in training videos.

The number of cable lines is so large that cable trays and boxes are used for laying them.
Metal cable trays come in the following types:

• Ladder type;
• Sheet without perforation;
• Sheet with perforation;
• Wire (mesh).

In addition, the trays are covered with lids and partitions are installed in them.

The designer is faced with the task of choosing the right type and size of the tray, indicating it in the drawing.
The choice of tray type and size depends on:

• Architectural plans;
• The presence or absence of a suspended or false ceiling in the room;
• Indoor environmental conditions (moisture, dust, water, etc.);
• Categories of premises according to explosion and fire hazard;
• Locations of consumers, their power.

Also, during the design, changes to these initial data are possible and the designer needs to be able to quickly make changes to the drawings.

In my work, I came across and used several methods for drawing cable trays and found the optimal one for myself. We'll talk about them further.

Methods for drawing cable trays in AutoCAD

1. Drawing cable trays using basic AutoCAD primitives

The easiest way that I haven't used. Trays are drawn using lines, polylines or squares (rectangles). This method is used by people who have little knowledge of AutoCAD. It is no different from drawing on paper by hand. Very long and laborious.

In one of the companies I worked for, the designer drew trays with squares. When it was necessary to move the tray to the other side of the corridor and change the laying route, it took him a very long time. The entire drawing (trays, wiring, sockets, lamps) was drawn with simple lines in one layer. He did not use AutoCAD blocks in his work.

2. Drawing cable trays using a multiline

A more advanced way to draw cable trays is to use the built-in tool multiline. Called by the command _mline (MLINE).
A multiline is a set of lines that make up a single whole. This method allows you to quickly draw a route of cable trays with bends at any angle.

Multilines have styles. By default, the drawing is set to the STANDARD style, which consists of two solid lines. You can edit it to suit your needs or create a new one.

2.1. Drawing cable trays using a multiline with shading

When I first learned AutoCAD, I used this method to draw a cable tray. To make it more similar to the ladder type of tray, I used shading (I applied ANSI31 shading, and selected a multiline as the object. Different areas had to be drawn separately and hatched separately so that the shading was perpendicular to the tray route. It looked like this:

Team "Multiline" contains parameters "Location", "Scale" And "Style". Using the parameter "Scale" You can change the width of the multiline.

Setting up multiline parameters

2.2. Drawing cable trays using a multiline without shading

The method of drawing cable trays using a multiline is convenient, but it takes a lot of time to hatch the drawn multilines to make them more similar to the tray. I started looking for a way to solve this and found it. A multiline is a set of lines. All I had to do was add a line in the center that would draw the crossbars of the tray. There is no such line in the basic AutoCAD package, so I made my own line type.

Cable tray drawn as a multiline using a custom linetype

Drawing cable trays using this method is available in . In addition to the obvious advantages, this method has one drawback. Multiline does not have the Length property. Therefore, you need to count the lengths of the trays manually. But I implemented it programmatically. To count the drawn trays, DDECAD users simply press one to get the total length of each tray type and size.

Also, if you need to change the type of tray and they are depicted differently in the drawing, then you will have to redraw the entire tray.

3. Drawing a cable tray using AutoCAD blocks

In order not to draw the same element several times, AutoCAD has a wonderful Block tool. Something is rendered once, then combined into a block. Next, this block is inserted into the drawing as many times as necessary.
The convenience is as follows:

1. A block is a single element. It’s easier to select, move, rotate, delete.
2. A block (actually a definition of a block) is edited once, and the changes are propagated to all copies of it (occurrences of the block).

I also used this method along with the multiline. I made several blocks of trays of different widths and types. I drew the route of the trays with them, and calculated them using the data extraction command _dataextraction (DATAEXTRACTION).

Of the obvious disadvantages of this method:

1. Blocks have fixed dimensions (width, length) and image. If you change the type and/or size of the tray, you will have to replace one block with another.
2. The route of cable trays can have completely different lengths, not a multiple of the whole number of blocks. This may not have a positive effect on the rendering. What will have to be drawn with lines or superimposed one block on another.
3. The route of cable trays can bend at different angles. This may also have a detrimental effect on rendering. Something additional will have to be drawn with lines.

The first problem can be solved in two ways:

1. If necessary replace All trays of one type with trays of another type (replace one tray block with another), then you can use the “Replace one block with another block” command from the Express menu.
2. If you only need to replace a part, then this is more difficult. You can change it manually if there are few blocks. You can transfer it to a separate file, replace it there using the first method and then transfer it back. I solved this problem by using lisp CHINSERT.

4. Drawing a cable tray with dynamic AutoCAD blocks

AutoCAD 2006 introduced dynamic blocks. This made the creation of drawings even easier and faster. Using the capabilities of dynamic blocks, I replaced several dozen tray blocks with one single, much more convenient and functional one.

Dynamic cable tray block in AutoCAD

• Selecting the tray type (also changes the appearance of the display) of the tray;
• Turn;
• Changing the length of the tray;
• Changing the tray width;
• Mirror image of the tray.

• Exact tray type - name of the tray type according to the catalog
• Number of partitions in the tray.

Attributes are hidden (invisible) and are not displayed in the drawing. They can be used to create a specification using the command _dataextraction(DATAEXTRACTION).

I made a total of four types of tray, with and without lids. In the end there were eight:

• Staircase;
• Ladder with cover;
• Sheet;
• Sheet with lid;
• Perforated;
• Perforated with lid;
• Wire;
• Wire with lid.

5. Drawing cable trays using special programs

Another way to draw cable trays is to use third-party programs and add-ons for AutoCAD. The main problem with this method is that in regular AutoCAD these trays turn into proxy objects. They cannot be edited or changed. They do not have the same properties that are available in the original program.

If you received a drawing in which the trays were drawn in a special program, but you don’t have it, then you will have serious problems editing the drawing. I sympathize with you. Either you will have to remove the tray and draw it again, or use Alexander Rivilis's utility and blow up the proxy object, and then edit the resulting lines.

I have not used and do not use this method of drawing cable trays.

For many years, the enterprises of the KOROBOV group of companies have been offering new cable structures with unique performance characteristics, and therefore many designers are faced with the problem of importing equipment into software systems, because AutoCAD, NanoCAD, Compass, etc.

To solve this problem, the specialists of the KOROBOV company have prepared an “Album of typical UZEMI solutions” in DWG format. It should be noted that UZEMI cable structures are industrial solutions for enterprises in the raw materials and generating industries, and the DWG format is a kind of standard and is used by almost all large companies in the field of design.

From the name it follows that the album of standard UZEMI solutions is presented in electronic format and is intended for direct insertion of structures when laying out a cable line in the design program. The album includes load-bearing structures, as well as straight elements of the cable line, including:

Angle of rotation of the route at 90 and 45 degrees

Angle of rotation of the route by 90 and 45 degrees upward

Angle of rotation of the route by 90 and 45 degrees downwards

Branch and intersection of the route at 90 and 45 degrees up

A distinctive feature of the UZEMI Album of Standard Solutions is the possibility of block design of cable lines. All products are presented in so-called blocks, and the layout of cable structures is done by copying and substituting the necessary elements.

The album contains standard solutions based on UZEMI cable structures (punched cores, boxes and four-sided trays). The album can be downloaded as one file in the .

Specialists designing critical industrial facilities must use innovative solutions in their work to replace obsolete equipment. Presented typical UZEMI solutions in DWG format, allow you to significantly reduce time costs when introducing new equipment.
