Connecting to 3D symbols

Hi Bouladjeraf. This thread about capture tolerance does not apply to 3D symbols. Panel Layout Mode symbols can be 3D. They only need connection points if Shortest Distance is going to be used on the project. Capture tolerance only applies when drawing wires, and the user does not draw wires to panel layout symbols. The user does often draw cables to 3D LAYOUT mode symbols in Bentley Substation, but that works with hook points, not connection points, so again capture tolerance does not apply.

thanks matt for your support the trooble is showing as below to draw bus bar the first disconct point is found but CB point connection not founded 

Bouladjeraf, hook points are added to symbol definitions to specify relationships with other symbols. Only symbols with matching hook points are quickly and easily "snapped" together during placement. This includes cable and bus insertion. So the cable you are trying to insert must have hook points that match the hook points found at the area of the symbol you are trying to connect to. By "match" I mean the same number of points (1-point, 2-point, or 3-point) and the same colors. The 3D sample symbols provided with the software already have hook points on them, so it may be a matter of finding the right cable/bus to use with the equipment.  You can look at the symbols you've inserted into your model to see the hook points (you may need to use Toggle Hook Point Visibility in the 3D Layout Design task). On the Insert Substation Objects and Insert Cable/Bus Object dialogs, you can switch to a Hook Point tab the lower right area to see what hook points are on the selected symbol.

Otherwise, if you are using custom symbols, hook points may need to be added. Again they should match the hook points of symbols you want to be able to connect and not match symbols that should not connect. For example, the hook point on the bottom of a circuit breaker should match the hook point on the foundation it will sit on, which should be a different hook point than the ones placed elsewhere on the symbol for cable connection. Besides matching hook point color and points, orientation is also important.
