For instance, the 4 surfaces in the Figure below. In the 2009 standard, this symbol cannot be applied to a surface in this manner. Extension lines can be used to clarify which surfaces are to be considered, however is not necessary. If an additional control is applied the feature of size, for instance perpendicularity as see above, this perpendicularity would be applied to all three cylinders as if they were one cylinder. When the Continuous Feature Symbol is applied as seen above, Rule #1 would be applied to the 3 cylinders as if there were no interruption. Without the Continuous Feature Symbol, these three cylinders would ordinarily be able to deform in differing directions in form and location by the maximum amount allowed by either Rule #1 or any geometric controls placed on the feature. This means the feature of size in question, like the boss below interrupted by the O-ring grooves, would be controlled as a single feature. The 2009 edition of the standard introduces the use of the Continuous Feature symbol as it to be used on features of size. Continuous Feature with the ASME Y14.5 – 2009 Standard:
The symbol has differing capabilities when considering ASME Y14.5 – 2009 vs 2018. Rule #1 and any geometric controls will be applied to the disjointed features as if they are one feature.

You can see a brief demo of these tips in the video below. Deselect this option to move the attachment point opposite the dimension line.ĭeselecting Dimension Elbow moves the datum feature symbol from the elbow to a position opposite the dimension line. Select Dimension Elbow to change the attachment point to the elbow.Similarly, if you place the datum feature symbol on a diameter dimension, you can choose whether it attaches to the dimension elbow or to the dimension line opposite the dimension text as follows: Select Gtol Elbow to change the attachment point to the elbow.Ĭhange the Attachment Point for a Diameter Dimension.If you place a datum feature symbol on a GTOL, you can choose whether it attaches to the GTOL frame or to the leader by choosing the option from the right-click menu. Change the Attachment Point for a GTOL Symbol
You can modify the placement of the datum feature symbol by dragging it.ĭragging a datum feature symbol. Click anywhere in the graphics area to stop editing the datum feature symbol.In the Datum Feature tab, set the properties for the datum feature symbol.Drag the datum feature symbol to place it on a surface or another annotation.A datum feature symbol will appear next to your cursor, and will move with your cursor. In the Annotations group on the Annotate tab, click Datum Feature Symbol.Now you can quickly create annotations anywhere you want, with smart, standards-based placement options that follow the latest GD&T standards.ĭatum feature symbols can now be created as a stand-alone annotation and do not require a plane or axis in the model. Among these new capabilities, we've made it easier than ever to create datum feature symbols.
