Dynamic Piping Parts Blocks

Dynamic Piping Parts Blocks

Purpose: to be used in designing the installation part of piping objects.

Elliptical blanking (2) as per GOST 173792001, stamped bottom as per OT08.00-60.30.00KTN036105.

Pipe (external diameter type). For the block, it is possible to specify various projections of the pipe ends: without a weld, seam, pipeline break symbol, as well as weld projections when turning the pipe through 60, 45 and 30 gr. The block can be rotated by a calculated angle, setting a certain slope, it is also possible to depict the pipe in 3 (axial + 2 contour), 2 (2 contour) and one (along the axis) lines. You can also specify a mask for the block (hide background) on the Properties tab (the selection grip is hidden).

For blocks, the main views and projections are given, as well as their variations: with and without centerlines. Rare or complex views (projections) of parts are not driven in. The basic part settings are also listed, and you must enable Show Properties on the Properties tab for the block to display them.

Separately, blocks are shown for the image of underground pipelines, they have different layers for the image of contour lines.

Blocks were created by copying data from the GOST tables into Excel, then through the export to dynamic blocks utilities, thus minimizing the possibility of manual input errors.

Updates:

1. Updating 09.03.28. The view names have been renamed, the transition view has been added, the retract projections have been adjusted, and new projections for the tee image have been added.

2. Updating 09.04.02. For taps, tees, transitions, blinds and pipes, a choice of nominal pressure has been added. The "Flange" unit has been significantly expanded, almost all sizes according to GOST 1282180 * and GOST 1281580 * have been introduced into it, a variant choice has been added, for the "parameters" type, data on the number and nominal diameter of bolts (studs), weight (taking into account the design) are given.

3. Updating 09.04.08. Added attributes for dynamic blocks, removed nominal pressure selection because it can be specified in attributes. Added the ability to select a mask for the pipeline.

4. Updating 09.07.10. In order to simplify the unit, the branch was divided into 4 units: 90, 60, 45 and 30 gr., And also the transition unit was divided into two units: eccentric and concentric transitions. For the discharge unit 30 gr., diameters less than 700 are excluded, as are not commercially available.

5. Updating 10.02.02. Blocks are duplicated to display the piping parts of the underground gasket (the contour line is shown dashed on the new layer "TX _ Pipes _ Parts").

6. Updating 10.03.18. Added views to display pipe parts without centerlines. For the Pipe block, it is possible to display the pipe in 3, 2, and 1 lines, driven the values ​ ​ of the slopes with the sign "minus" - now it is not necessary to rotate the block to set the slope to the desired side. The Tee type base has been expanded by adding trellis tees (with an elongated neck). The Show Properties grips for all blocks and the Mask grips for the pipe block are hidden. The location of the selection handles has changed slightly for convenience.

7. Updating 10.06.05. Values in lookup of blocks of the T-connector and flange are corrected that gave the wrong image of T-connectors 57x57, 57x45 and 76x57 and flanges 1500XX.

8. Updating 14.06.27. Corrected the value in the tee block lookup, which gave the wrong image of tee 426x325.

Application:

It is proposed to use blocks by copying from a file or based on a AutoCAD template. The copied block must be set up type, view, "fit" on the pipeline, and attributes (if necessary).

All blocks have two selection grips, one for the part type and one for the part type. For ease of use based on block rotations/mirrors, the Type grip for all blocks is closer to the base point, and the View grip is further and diagonally. In addition, the Pipe block also has grips for specifying slope and pipe end images.

All blocks have 2 attributes, piping and part. The first attribute indicates that the part belongs to a pipeline (site, node, building, network), here you can specify the pipeline number, environment, pressure, pipeline category, etc. The Part attribute is used to schedule the part itself, such as the BOM number or its full name.

In addition to the basic views (projections) needed to build pipelines, the blocks have a view of Show Properties, which provides additional (reference) characteristics that can be useful for scheduling, quantity takeoff, or checking that the blocks are correct (included on the Properties tab).

If you use a Pipe block with a mask on (enabled on the Properties tab), the background hide is set on the Draw Order tab. Use the _ tframes command to show (hide) the mask.

You can quickly calculate the number of dynamic blocks using the special calculator VetCAD++.

After you build a pipeline, you can use data extraction. Data extraction allows you to obtain information in tabular form about the number of blocks, their characteristics (length of pipelines, projection of parts, etc.). To access the data extraction function, go to Service???? Extracting data..., or the _ dataextraction command. You must select the features to extract (or the entire drawing), save the extraction, then select only the blocks, then select parameters for "dynamic blocks" and "attributes," customize the table display, and, most recently, export to an external file or paste into the drawing. As a result, we get drafts of the BOM, Work List, or Piping List. For all parts, there is a Length option - for ease of counting piping erection quantities.

How to explode blocks:

Blocks are built using additional visibility parameters, which requires certain conditions for correct explode. Blocks are supposed to be used at a scale of 1:1 (the scale along the axes x, y, z is ± 1), but it is possible on other scales (the scale along the axes x, y, z is ± m). For a correct explosion (we get what we see), it is necessary that the scale along the z axis is -m (-1 for a scale of 1:1). If this is not true (all axes are the same scale), objects created in additional visibility settings disappear, for example, the right weld joint for the Pipe block, the text in the Parameters view, the mask in the Obscure view for the Pipe block. If the scales in axes are not equal modulo, then the grips of dynamic blocks disappear. Sometimes, when you reduce blocks (noticed when you reduce blocks to scales 1:50, 1:100), the handles disappear. This is a AutoCAD bug that is corrected by redefining the scale for blocks on the Properties tab.

Creation history and possible ways to improve blocks:

The idea of creating dynamic blocks of widely used and standardized products such as pipeline parts is not new and has previously been found on the Internet, but implementation was quite primitive, which led to the creation of the presented blocks. I proceeded from the principle that for one type of product, for example, a branch, there should be one block, including all its variations, both in size and in projections and views. Initially, there were only the main three views of the parts (front, profile, top view), but later individual views were highlighted. But during the application of the blocks, it turned out that some blocks are too loaded, some species are practically unused, other species (projections) could seem to be added, but this is extremely difficult to implement. Some functions turned out to be underutilized and had to remove their "grips" from the image of the blocks (for example, the view "Parameters"), leaving the most necessary .

The ability to draw a pipeline "in one line" by the represented blocks is not implemented (except for the Pipe block), it is only possible to turn off the contour line and redefine the properties of the centerline so that the latter looks like a contour, that is, it is a pipeline line. This solution, in my opinion, is not simple, a one-line pipeline can be easily built and without the use of blocks at all, the more often the scale of parts is not maintained in the drawing.
