Attributes for parts lists
Each block has the designation as a visible attribute (for example O-ring 29.87 x 3.53). The invisible attributes are SIZE_CODE, ID_MM, CS_MM, STANDARD, MATERIAL, HARDNESS_IRHD, PART_NO, MANUFACTURER, QTY and REMARKS. The size code, inside diameter and cross-section are already filled in; set the material and hardness to what you order.
Export the O-rings of an assembly drawing to Excel with BlockSync to get a parts list with size, material and quantity, and write corrections back in one run, with preview and backup.
How to use the library
- Unzip the file and open the DWG. Copy the symbols you need into your plan, or drag the blocks in from DesignCenter (ADCENTER).
- The rings are drawn at real size, 1 drawing unit = 1 mm: the inside circle is the inside diameter and the outside circle is the inside diameter plus twice the cross-section. Insert them at scale 1. Small rings are drawn small; the catalog sheet enlarges them only so that you can see them.
- The insertion point is the centre of the ring. The end view is on the left and the cut cross-section, two circles of the cross-section diameter above and below the centre line, is on the right, so you can use the same block in a plan view and in a section view. Explode the block and keep the view you need.
- The five libraries differ only by cross-section, so take the library of the cross-section you need and look up the size by its code or by its inside diameter. The block name is ORG_ followed by the size code, for example ORG_210.
