Cut (drill) solids by solids.

I agree with Jan, please provide more information.

There is the 'Perforator' Technology Preview which may be of interest introduced in MicroStation Connect Update 11

https://communities.bentley.com/products/microstation/b/microstation_blog/posts/new-in-microstation-connect-edition-update-11-perforators-technology-preview

But as mentioned this is Tech Preview so will have to find another method like using cut solid tool oBhttps://communities.bentley.com/products/microstation/w/microstation__wiki/10784/how-to-break-a-solid or the Boolean Tools to subtract one solid from another.

Carl,

Thanks for links, 

Command Cut solids by curves allow us to cut solids only in one direction (I think...). I need to cut hole using B-spline or arc (set cutting direction or something like that).

Cheers

So we have a very similar issue.  We are using OpenBuildings Designer, CONNECT Edition.  We have a concrete structure that we are embedding piping into the walls and some into slabs.  In trying to cut a cavity for the piping, we have tried to "Extrude Along" and then "Subtract" that solid from our concrete walls.  Yes, the walls are put into the model using the Building Design "Place Wall" element.

After we create the Extrude Along the element shows as dashed lines, not as solid lines as other elements do.  When we try to Subtract, the element created by the "Extrude Along is not recognized.

Below is a couple of screen shots showing the Extrude Along element as well as it's properties.

Can anyone shed a little light on why our situation is not working as described earlier in this thread, or does anyone have any other solutions for removing the element from our walls.

Hi Tim,

Could you send us sample file please. I will have look and try to help.

Tom

Hi Tim, I think I've got something for you.

I will try to explain step by step my method.

1. As you said you have used "place wall" command, so... let's do it:

2. Using "Plumbing Design" let's place some pipework inside the wall...

3. Explode (Drop Element) the pipework and leave only centre lines.

4. Remove little pieces around the bends and extent the straight lines to the bends centres...

5. Change the line type to "0" (Continuous):

6. Use Create Complex Chain to make one piece of our future pipework...

7. Then "Solid by Extrusion Along"... and pick your outside radius (hole size). Keep Inside radius 0.

8. And the last step....  Subtract Solids...

And finally we have ducting inside the slab/wall....

Hope it helps.

Regards

Tom 

Nize workaround, but..

It would be great to build the ability to sleeve piping in concrete etc. Dropping, reconstructing in order to boolean is not particularly productive or scalable.

See Bentley's 'other' BIM app Speedikon, which provides an enlarged penetration / boolean subtract around a beam when it intersects with a wall.

I believe that OBD's beams (and presumably, pipes/ducts) can already be defined with an insulation thickness. A similar setting for the sleeve could be provided, leveraging the same code?

Tomasz,

Thanks for the information, but this still isn't working.

#1.  It appears as though you are using V8i, and I am using OpenBuildings Designer CONNECT Edition, Update 6.

#2  After I create the pipeline I can not get the Drop Element to explode my pipeline even with every option picked.

#3  After fighting for a while, I decide to create the path using a smart line with rounded corners and jump straight to your step 7.

The Solid by Extrusion Along worked just fine.

#4.  I moved the pipeline into place in the wall(s) that I am trying to subtract the pipeline from.

#5.  If I try the Subtract from the Modeling discipline, I can't pick the walls.  Note the curser in the shot below.

If I try the Subtract Solids from the Building Design discipline, I can pick the walls but not the pipeline.

Now, I have only been using the Bentley products for about a year, and I am learning as I am designing.  But, if Tom can create the solid and subtract from a wall, shouldn't I fundamentally be able to do the same thing?  Or, does the CONNECT Edition of OpenBuildings not have the same "EXACT" functionality as V8i?

Hi Tim,

I am sorry I couldn't help you. The CONNECT Edition might be different...but still weird you cannot do basic operations on the solids as the Vi8 allows you... I will be back if I figure something out.

Tom

Tim,

After creating the extrusion, first try converting it to a Smart Solid using the Convert To Solid tool (Modeling > Solids > Solid Utilities).  Then, use the Subtract Solids tool from the Building Design > Modify tab.
