Need to create Cylindrical Datum Point(s) X,Y Feature in Creo using export from MathCAD

Question

First I only have MathCad Express Prime 3.1

Created a spreadheet that gives me the X,Y points for my spiral

Copied the X,Y outputs from Excel into MathCAD

How do I create a Datum Point Feature using this X,Y output from MathCAD? When I click on import while in the Datum Point (cylindrical) feature it only allows things like pts file.

'll keep plugging away at it but if anyone has ideas that would be excellent

I just read your first post where you state, that you use Prime express 3.1.

I am Prime-less at the moment (and I don't miss it) so maybe some good soul can convert the sheet for you so you are not forced to retype the whole thing.

As you are using express you are not allowed to use programming.

Therefore we unfortunately have to rewrite the function R(theta) more EXCEL-like:

I attach the changed file.

This and the rest should work OK in the express version, I guess (apart from some formatting problems which have to be corrected by hand).

You may also download and install the trial version of Mathcad 15 yourself so could open the file directly and you would be able to convert MC15(and below) sheet to Prime format yourself during the 30day trial period of MC15.

Does your problem lie with Prime (doing mathematical operations etc) or with Creo (what many people frequenting this community do not know/use)?

I see in pcture2 that you have a table of X,Y points in Prime. Is there a mathematical operation needed to be performed on this data? If yes, what is it?

Then for the export from Prime to Creo, you may be better off asking in the Creo community.

Success!
