I'd like to draw the bounding box of a selected entity. I can have it done by drawing line by line, however, I see it offer the BoundingBox but I cannot get it to work. I am not sure how it can add the box to theModel so it can be drawn.

I need to create a diagonal matrix in python from an X matrix which is repeated 3 times. In matlab I do it in the following way:

As can be seen below, there are four dataframes that I would like to merge into a single dataframe by stacking rows on top of each other. The column names are same, so not sure why this is not working.

I would like to obtain a matrix of correlation with bootstrapped confidence intervals.

I found the jmv package giving the correlation matrix with the p-values and the confidence intervals; but in this case, they are calculated with the Fisher Transformation.

I found how to obtain the bootstrap confidence interval:

On R, I used the boostrap method to get a correlation coefficient estimation and the confidence intervals. To get the p-value, I thought, I can calculate the proportion of the confidence intervals which do not contain zero. But this is not the solution.

How can I get the p-value in this case ?

I am using cor.test to get the coefficient estimation. cor.test may also gives me the p-value from every test. But how can I get the bootstrapped p-value ?

Thank you very much !

Below an example :

I'm making use of DevDept's Eyeshot library to manage 3D graphics files which contain geometries that represent the parts of a metalcasting mold. Largely these are either basic Brep primitives or STL-file type imports, combined into one scene.

Each geometry is associated with thermal properties for use in the simulator. If I use STEP as an export format, I'd like to include the thermal properties as metadata, either as a separate custom entity with an index, either a number or string key, or the properties themselves.

In either case, the thermal properties are easy to express as a multiline JSON string.

Is it possible to include descriptive metadata like this in a STEP file? What would be a good approach to accomplish this?

I am confused about Brep (Boundary Representation) and polygonal mesh. Because both of them are a collection of vertices , edges and faces, but in computer graphic books Brep is explained under Solid Modeling section while polygonal mesh is explained under surface modeling. So what is the difference between two representations?

I am new to C and currently doing a BREP (boundary representation) implementation in C, the idea is: given a topology matrix and a vertex matrix to produce ordered tables with information of the connectivity of the solid. The problem I have is in these two loops:
