Relimitting Source Solids in Spry

This article covers the steps required to relimit source solids using a grid surface. This example covers a suggested method but this can be tailored to your models requirements.

Creating Relimitted Table Fields:

The following Fields will need to be created to write the new relimitted values for things such as Volumes and also the new cut solids.

It is recommended to create a new section under your Deposit table to hold these relimitted fields and not overwrite the existing imported information.

Relimitting Utility:

To get to the relimitting utility, right click the Deposit Table in the Project Explorer and select Utilities > Relimit Solids:

Global Options:

Relimit Mode

• Choose between Remove above (all solids/volumes above the surface will be removed) and Remove Below (all solids/volumes below the surface will be removed)

Surface

• Choose your grid or triangulation to compare your solids against
• If you cannot find the surface you are looking for, make sure you have imported the surface into your Design Data.

Range

• You can apply the Relimit Solids tool to an Inline Range or select from a picked / text Range that was created prior. This will limit the nodes which the Relimit Tool is applied to.

Clear Selected Fields

• Checking this option will clear data from the fields being populated before the results of the scan are written to them. This will be filtered on the range applied in the step above.

Export Only Modified Solids

• In order to reduce the number of solids in your model, it is recommended that you check this option. Only those solids that are intersected by your surface will be exported to your selected Relimited Sold Field

Upper and Lower Clamps

• Clamp values instruct the Relimit Solid tool how to behave when it encounters a solid that is very close to being either completely above the scanned surface, or completely below. The effect of this to eliminate very small remaining values
• Using an upper clamp of 95.00% means that if a scanned solid is at least 95% remaining after relimiting, it is treated as 100% remaining (full solid)
• A lower clamp of 5.00% will treat any solid less than 5% remaining after relimiting as 0% reamining (no solid)

Note, the behaviour of the clamps does not change if you are removing material above or below a surface, as it refers to percentage of the original solid that remains post relimit.

Solid Options

• In the lower left of the window, select the Solid Fields you want to compare against your surface. Make sure the box next to the solid is checked.
• You can select multiple solids to compare against a single surface. If you do, you should create a separate set of fields to hold the data from each scanned solid.

Once you hit ‘Next’ spry will go ahead and calculate the relimited values:

If there are any issues with the solids you will receive a summary of the problematic solids and a reason the solid failed. One of the most common issues is that a solid will self-intersect with itself, or the solid is not closed – in these cases it is recommended you run some repair and validation checks on these solids:

Once the relimitted calculations are done, before we can view the results we have to modify the default source quantity fields and solid fields in our processes setup to show the new relimitted values.

Updating Default Source Quantity and Solid Fields:

 

Before we can see the visual change of our updated solids in the Animation view, we need to update our processes fields to show the new relimitted values:

Once the processes fields are updated, we can hit the ‘Reload Solids’ button in the animation view to see the change:
