Full parametrization of geometry is recommended for creation of sketches. In this case there will be less changes to sketches in case of model rebuild.

Diagnostics of a parametrized sketch

Existence of parametric features during creation of drawings does not restrict your style of creating drawings. You can select the image which is more convenient for you to work with: parameterized or regular. If necessary, one document can combine parameterized and non-parameterized objects. Besides, you can freely jump from one geometry representation to another, for example by applying parametric constraints to a previously created regular drawing or by deleting constraints applied to a previously created parametric image.

Applying parametric features for working with drawings should be carefully considered, estimating the real necessity for full parametrization of a particular drawing.

We can give the following recommendations related to parametrization of drawings.

•It is reasonable to parameterize drawings of parts which, when modified, only change dimensions and do not change topology. Thus, a once created parametric image of a part can be quickly rebuilt by simply changing dimension values.

•If this is a new development, you should estimate if it will be applied as a prototype in the future. If not, then parametrization of the drawing may not be performed, as there is no need of future quick modification. But if the new part will be frequently used as a standard prototype, then it makes sense to parameterize its drawing or to create a parametric fragment.

•Most likely, full parametrization of complex assembly drawings will not be feasible as in this case volumes of setting constraints and control dimensions are quite large.

•Try to estimate the advantages of applying parametrization on particular drawings which are standard for your organization. Later you can keep in mind the obtained results while creating new designs or redeveloping existing drawings.
