Hello,

In the attached sheet, Part 1 "Data input...." you will see "Number of Point Loads" is 4. In part 2"Input of all Loads", you will see 4 point loads. if i canhe the number of point loads to 10, how could i make the input of point loads cells to match the number of point loads 10? i can change the number of point loads to 10, but i want to be able to input more than 4 pont loads as shown in part2"Input of all loads", Thanks!

Man, that's quite a work of art.

Let me start with a small quibble or two:

1) You define kiop as 1000 lb. If it's force (which is usual), it should be 1000 lbf. [Mathcad recognizes lb as mass and lbf as force, (the weight of one lb mass under the acceleration of gravity at the earth's surface.)]

2) You define the ORIGIN as 0 (you don't have to!) then start all of your index variables (i, j, and k) from 1. This leaves the first element in any vector undefined. (Mathcad stuffs in a zero and moves on, but it's sloppy!)

Now, adding places to the table! I'd not seen this method of inputing values before. You can do it; select the last element in your input (4 kip) and type a comma--another space appears! But I'd like to suggest another way--define the vector of loads and count how many you have.

I'm having trouble with this *.xmcd file format in Mathcad Prime.

What am I missing on getting it to read?

Is there some confusion here between *.xmcd and *.mcdx ?

Any hints for someone, and old time (*.mcd) user trying to manipulate archane champion's PTC's making the "simple" complex?

Thanks!

Mathcad Prime 1.0 can only open the file in the format ".mcdx". But you can use the converter "XMCD, MCD Converter" to convert files from earlier versions of Mathcad (formats ".mcd", ".xmcd"). However, when converted into the format ".mcdx" it should be noted that this will not be converted: 3D-plots, symbolical calculation, mathematical formulas in text fields, instead of them in the new converted file will be inserted images.
