The general requirements for standard part modeling are as follows:
(1) Software environment requirements for modeling: Develop a unified standard part modeling template that specifies basic attribute information, extended attributes, and related parameter attributes of the standard parts, and specifies the association information between the attributes.
(2) Attribute filling requirements: Part number is the unique identification of the part. In the PartNumber attribute name, spaces, Chinese characters, slashes, etc. cannot appear. The physical file name and design table name of the part are consistent; according to the standard drawing requirements All the features related to the model are reflected by the parameters. The parameter requirements are meaningful. If possible, use the drive dimensions marked by the standard parts drawing. Do not increase the control size arbitrarily; define the parameters after creating the reference parts. Define attributes such as ID number, name, material, specification, and single weight.
(3) Design table naming requirements: The design table requires the same name and part name, created with excel.
(4) Sketch requirements: The model sketch of the reference part is to be “fully constrainedâ€, and the constraint size on the sketch is to be associated with those parameters already defined.
(5) The creation of seed files should be strictly in accordance with the relevant specifications of 3D modeling.
Drop-in kitchen sinks, also called self-rimming sinks, overmount sinks, or top-mount sinks, are sink basins that install and sit on top of your kitchen counter. There is a visible rim or lip on the perimeter of the basin that rests just over the cut-out for the sink. Drop-in sinks are supported by this lip and a series of hidden clips that attach to the underside of the countertop.
The Advantages of Drop-In Sinks
Drop-in sinks have some clear advantages over other styles, especially in the kitchen.
Cost
They`re generally cheaper to buy and easier to install than undermount sinks. In fact, even weekend warriors and DIY newbies should have no problem installing a basic overmount sink. If cost is a consideration in your kitchen, an overmount sink with a do-it-yourself install is a great way to stay within budget.
Cleaning
While cleaning may not be your foremost concern when choosing a kitchen sink, it should be considered. After all, you`ll have to care for and maintain your sink regularly. The basin of an overmount sink is easier to clean than the basin of an Undermount Sink.
Protection
If you`ve got soft countertops, drop-in sinks can help protect the edges of the sink cutout.
- Marble and some specialty counter finishes benefit from the added protection provided by the lip of a drop-in kitchen sink basin. It prevents the build up of water on the surface edges of the stone through repeated exposure of use.
- If you have laminate countertops, drop-in sinks are the only option: the particle board below the laminate surface isn`t strong enough to support undermount sinks but plays well with self-rimming basin types.
