GSoC Proposal: Automate Reinforcement Process of Slab and Footing in FreeCAD

[Shiv_Charan]

Hi @amrit3701,

I have updated merge request for edit python api and FootingReinforcement Group Object
here is updated merge request: https://github.com/amrit3701/FreeCAD-Re ... t/pull/166

Now footing reinforcement can be edited by

• Python edit API
• From Properties panel

I am currently working on Footing reinforcement GUI and It will be complete very soon.

Example of Footing Reinforcement python edit API is as following.

In this example rebar mesh alignment and count of column in x direction and y direction is change.
similar other properties can also be changed to update different types of footing reinforcements.

Hi @amrit3701,

I have updated merge request for edit python api and FootingReinforcement Group Object
here is updated merge request: https://github.com/amrit3701/FreeCAD-Re ... t/pull/166

Now footing reinforcement can be edited by

• Python edit API
• From Properties panel

I am currently working on Footing reinforcement GUI and It will be complete very soon.

Hey Shiv,

Nice progress. Can't wait to see the GUI footing reinforcement.

Google Summer of Code 2021 Timeline:
- August 16 - 23 18:00 UTC Final week: Students submit their final work product and their final mentor evaluation
- August 23 - 30 18:00 UTC Mentors submit final student evaluations
- August 31 Final results of Google Summer of Code 2021 announced

Thanks,

[Shiv_Charan]

Nice progress. Can't wait to see the GUI footing reinforcement.

Hi @amrit3701

I have created a merge request for Footing reinforcement GUI for making or editing footing reinforcement.
here is the merge request: https://github.com/amrit3701/FreeCAD-Re ... t/pull/167

Now user can make Footing reinforcement through:

• makeFootingReinforcement python API
• GUI to make footing reinforcement

To edit footing Reinforcement user can use:

• editFootingReinforcement python API
• GUI to edit footing reinforcement
• by using Properties panel of freecad

Detailed steps to make Footing Reinforcement through GUI:
file used :

rectangularFooting.FCStd

(10.61 KiB) Downloaded 110 times

1. Select any face of a previously created Footing Structure object. as shown in below image.

FootingSelectedFace.png (12.55 KiB) Viewed 7448 times

2. Then select Footing Reinforcement icons from the rebar tools.(currently there is temporary icon)

3. A footing reinforcement dialog box will pop-out on screen as shown below.

4. Select the desired raber type and other input data for rabars in parallel direction of selected face in footing reinforcement mesh as show in below image.

5. Now click on Next button or select Cross Rebars in list view and desired data for input data for rabars in cross direction of selected face in footing reinforcement mesh as show in below image.

6. click next or click on Columns in list view and fill desired input for columns in footing reinforcement.
Here you can select to add secondary rebars in columns or not.



7. click next or click on Ties in list view and fill desired input for Ties in columns of footing reinforcement.



8. click next or click on Main rebars in list view and fill desired input for main rebars in columns of footing reinforcement.



Only if secondary rebars check is enable then:
9. click next or click on XDir Secoundry rebar in list view and fill desired input for secondary rebars in X direction in a column in footing reinforcement.



10. click next or click on YDir Secoundry rebar in list view and fill desired input for secondary rebars in Y direction in a column in footing reinforcement.



11. Click OK or Apply or Finish to generate Footing reinforcement.

Footing reinforcement without secondary rebar take comparatively less time then with secondary rebars.

Output of above inputs:

SIde view:




To EDIT Footing Reinforcement Double click on footing Reinforcement object.
Edit dialog box will open similar to above images.

Thanks and Ragards

Hi @amrit3701

I have created a merge request for Footing reinforcement GUI for making or editing footing reinforcement.
here is the merge request: https://github.com/amrit3701/FreeCAD-Re ... t/pull/167

Hey Shiv,

Yes, I will test and review your merge request shortly. BTW, are you available this coming Sunday? I am thinking to schedule a meeting and summaries all the work done by you in GSoC period.

Thanks,

[Shiv_Charan]

Shiv, please list all notes/suggestions here also.

Hi all,

The notes/suggestions from above meeting are as follows:-

• Help button should open footing documentation on browser.
• cover under columns tab should be given more suitable names.
• images should be added in GUI dialog box to assist user while adding inputs.
• icon for footing reinforcement should be updated ( currently there is temporary image is used as icon)
• x and y direction value for columns should be update as per freecad view's x and y axis.
• multi threading can be added to speed up reinforcement process.

Here is a brief report of work done in Slab and Footing Reinforcement during GSoC: https://gist.github.com/ShivCharanSharm ... 808362ee73

I am currently working on these suggestion, and will improve these further.

Thanks and Regards

Hi @amrit3701,

I have created a merge request for following improvements from above list.
here is the merge request: https://github.com/amrit3701/FreeCAD-Re ... t/pull/168

• Set x and y axis of column matrix in footing to add column in footing as per freeCAD x and y axis in display
• Add redirect to footing/slab reinforcement documentation on help button clicked in there GUI Dialog Box
• Change front/left/right/rear cover naming to front/left/right/rear spacing naming for all columns in columns tab.

I am working on other suggestions and will be completed soon.

Thanks and Regards

"ping"

Hi @amrit3701,
recently I updated the Reinforcement WB to version 0.3 and gave the new slab tool a try.
Creating lower reinforcement for a slab I get a bunch of error messages and alternatively FreeCad tells me to recompute once the reinforcement, then the reinforced element .. and so on.
When I then try to delete the reinforcement group I run into an Access violation!
