Demo: Load from STEP file / Modify / Save to STEP file

Load the STEP file

In the menubar, click on File then Load STEP At Top.

Navigate to the file 'as1-oc-214.stp' and load it.

In the tree view window, left click on the part l-bracket_1 then right click on it to get the drop down menu.

Select Set Active. The color of the tree view item will turn yellow.

Now use the check boxes to show only l-bracket-assembly_1

Then zoom in using one of these techniques:

• MMB scroll wheel
• Ctrl+RMB
• RMB
• • Draw
  • • Fit All

Modify the active part

Apply fillets to the corners of the bracket, as shown. I applied a radius of 5mm to the inside corner and 10mm to the outside corners.

Now use the check boxes to show the entire assembly and right click in the graphics window to select Draw -> Fit. Notice that the changes made on the bracket are applied to both parts because they are shared instances of one part.

Next, let's edit the name of one of the bolts. Left click on one of the bolt_1 tree view items, then right click and select Edit Name.

Edit Part Names

Change the name to BOLT

Notice tht all the bolts now have the new name because they are all shared instances of a single part.

Save the Modified Assembly

Click File then Save STEP (Top) and save the modified assembly to a file.

Reload the saved file

Close Kodacad, then restart it and load the saved file

Notice that the modifications (both the geometry mods to the bracket and the name change) are still there but the color of the modified bracket has been lost somewhere along the way.

Todo: Figure out why modified parts lose their color

Seriously, if anybody can help me to figure this out, I would love to hear from you.
