Dear community
We are developing home appliances for food preparation. For regulatory reasons we need to provide the total surface and the surface in contact with food.
For a part I created feature measuring the area of the body to get the Total Surface. The I created a copy surface feature and again a feature stating the area of these copy surfaces. Using relations I created parameters which then are used in annotations. So far so good.
For convenience reason I tried to add this features, relations and parameters to our start part. Unfortunately the measuring and copy surface features fail if no geometry exists in the start part. I wonder if there is an option to add these features differently. Any hints?
Cheers, ziegi
I am not convinced that you will be saving much if any effort by trying to build this into a start part. How many times in a year will you use this start part within your company? This is something I have needed to manage in many designs and with multi-body modeling support it has become easier than it was prior to Creo 7.
The designs I work with usually have constraints associated with a control volume of a fluid so we create a fluid master model that represents the volume of a fluid contained within the design. In principle we design parts of this nature from the inside out. By doing this you have direct control over the surface area and volume in the Creo design intent. I realize that you probably are not working under such constraints but by building a model of the fluid volumes it may be more productive. You can develop your solid parts as a derivative model of the enclosed volume as needed.
If you have a model or body representing a control volume it makes managing the design constraints more efficient. You can directly measure the volume and wetted surface area in the fluid master using analysis features as you are currently attempting. These analysis features will contain the parameters for use in relations inherently.
I have used this approach to create design templates for blender jars which sounds like it is more applicable to your applications. The master model jar can be morphed into different volumes/sizes based on requirements. Using BMX this master model can be modified in seconds to hit a volume target.
An example on the opposite end of the spectrum using this approach where it is even more valuable is in the optimization of cooling channels for thermal management in a design. In contrast to designing a "solid" part and then measuring the volume, the fluid master application described above can be more expedient during design and analysis. In complex designs requiring simulation dependent on the geometry it represents an order of magnitude improvement in productivity during the design phase of a program within Creo as well as the simulation tools used to analyze the design.
