There is also a fair amount of customization that you can do without violating the standard. In addition to the standard itself you can even select a specific revision. The appearance and behavior of symbols will change according to your choice. Before you start drawing just go to the options dialog box and choose the standard you need on the AM:Standards tab. AutoCAD Mechanical toolset also provides many more standards. All the symbols in this video comply with the DIN standard. In the dialog box I select the symbol for a circular run out and specify the tolerance value as well as the axis.Īnd that’s it! We just added some rather complex annotations in almost no time. I specify the first vertex of the leader and now this segment can only be vertical or horizontal. I click to indicate the start point of the leader and AutoCAD Mechanical toolset forces it to be perpendicular to the shaft, as per the standard. AutoCAD Mechanical toolset draws an extension line as I move the cursor. I don’t have a lot of space here so I will start the leader outside the shaft. I click the Feature Control Frame symbol and select the shaft segment which I want to attach it to. In the same way I create the second datum identifier. See how AutoCAD Mechanical toolset helps me to keep the standard by forcing the first segment of the leader to be perpendicular to the shaft. I click the “Datum Identifier” symbol on the ribbon and select the attach point. I start with attaching the datum identifiers that specify the tolerance axis. I want to specify a circular runout tolerance. Even if I modify a surface texture or add a new one later it’ll change accordingly. Note how it automatically picks up the other symbols in the drawing and lists them in brackets, as per the standard. In the dialog box I flag it as a majority symbol and specify the roughness average. I will now add a symbol to specify the surface texture requirements for all other surfaces. Now we can access this symbol directly from the ribbon. I double click to display its properties and add it to the library. So I’m going to add it to the symbol library. That means I am going to use this value quite often. I want these two shaft segments to have the same roughness average as the one I’ve just added. When I’m done, I click OK to place the symbol. Now we can specify the options and select the value for the roughness average. I want to place the symbol on the shaft without a leader, so I just press enter when I am asked to pick the next point. I select the shaft and specify the start point. I’ll now go on and add a surface texture symbol. No problem! Whenever you want to check or change the properties of an object, simply double click it. Maybe you want to make some changes to the symbol later. Notice how AutoCAD Mechanical toolset automatically calculated the correct ratio. After that I specify the attach point and place the symbol. That is going to be the baseline from which I want to measure the slope from. Next, I’ll dimension the slope of this conical section. If you want to change the text, of course you can do so. Now see how the leader note automatically picks up this information and displays it as the default text. That means all the information about it is already stored in AutoCAD Mechanical toolset. I dropped this key from the content library earlier. Suppose you want to add a note to this key, just click Leader Note from the Annotate tab and select the key. It’s as easy as that! Now let’s see how it works and add some annotation symbols to this shaft. Simply choose a standard, select the symbols and insert them directly into your drawing. AutoCAD Mechanical toolset comes with all the frequently used annotation symbols and also supports numerous standards. If this has been a time consuming task of adding blocks, exploding and modifying them, I have good news for you. 25 0 obj>/Matrix/Length 298/Filter/FlateDecode>
