Start Parts

How and where can I create a start part to use on a new program? I've used start parts before, but never had to create one!

Well, if you have to start from scratch, you'll want to add the default datum planes, default coordinate system, set the units, possible set a default material, add the apprpriate parameters, layers (I suggest using rules), relations, views, etc.. It's a lot of work, but worth it.

... also you can start your Start Parts from existing models/assembly - it is easiest way how to create the Start Part (model, assembly have all necessary informations - units, relations, parameters, layers etc.). You can edit/add/delete new information for your Start Part and save as new.

Do not forget set configuration option for Start Parts (configuration_option and path_to_start_part):

- for solid part:

template_solidpart D:\start_models\start_part.prt

- for sheetmetal part:

template_sheetmetalpart D:\start_models\start_smtpart.prt

- for assembly:

template_designasm D:\start_models\start_asm.asm

Certainly you can take that approach and delete all features, etc., but I would rather start from scratch since I don't 100% believe that there aren't "remnants" left in the file. Model associations within windchill, external references, etc. I'd rather start with a clean new part, with nothing in it as EVERY part you make from now on would have these "remnants" in there if there was an issue.

Also, I've read that it's best to start from scratch every new major revision anyways, as start parts from, say v2001 may have issues when you use it as a start part in creo. I'm going to redo mine when I get the chance.

I have also made start parts that contain a first sketch based on what I'll be modeling:

Front Extrude
Top Extrude
Right Extrude

which include center lines for symmetry as well as:

Front Revolve
Top Revolve
Side Revolve

which includes on centerline and one geometry centerline for the revolve feature.

Kris, Your start part would then be unique to that particular part if it contained a sketch. For your next part, you would need to create a new start part, wouldn't you?

For the sketch I draw a visible square that can easlity be deleted once I open it and a Save As Copy can be used to save the new part.

Kris,

Do you find that you need to set your working directory to the directory that your start parts & current_session.pro are all located?

Re: Start Parts

No....our Pro is started with a batch file for our company, which starts in /ProLocal. I can just click browse and go to the start part I want in the second screen after you start a new part.

I have created start parts for most common steel shapes. For example I have one for angle iron. it ask you for angle thickness, stem one and stem two height, and overall length.
