Hi guys, I am currently working with microstation connect and windows 10.1 pro. I need your advice for something that I would like to do and I don t know yet how to do it.
basically I am working on a 2d dgn, and I have 2 issues
1st : I have a square surface from which I would like to remove another surface in this example a circle but it is gonna be a polygone surface in my project.
2nd: I need to split this surface so the square minus the circle into 8 "sub" surfaces in order to create a gml of less than 15sq meters which is necessary for a side app which need a surface of less than 15sq to work.
If you guys have ideas and willing to share these, I am all ears.
thanks anyways.
Are we talking about planar shapes, or actual surfaces like 3D topography?
Tool to be used: Create Region
If you provide a bit more info, I'll be able to give you a more definitive answer
Hi Barry,
Planar shapes
Let s say the source shape is 120sq kilometers , it is kilometers I ve made a typo. Minus the round shape it gives you a lesser surface it doesn t matter. The main goals here are to remove the circle shape from the square shape(basically I don t know how to do it. And to create 8 shapes that are smaller than 15sq kilometers each in order to create a gml from each shapes that will be used by an app which has 15sq kilometers limit.
Ok using a simple example:
This is the Create Region tool in action. With the visible settings, you can see it has created a grouped hole element with the circle removed from the square. We can now chop this up into smaller pieces with further steps.
This is great I solved my first issue, tank you very much for your time, Barry you rock!!
Do you have any lead for the second part of my problem?
Thanks anyway
There are a number of different ways to do it, using Create Region once again is likely the simplest:
Here I draw 6 lines equally spaced apart; 6 because I know it will result in 8 pieces due to the size of the circle but you need to work out how your splits need to be configured. Once I did that, I locked the lines and the group hole element. Then I activate Create Region again and enable Keep Original so that my new smaller regions will not be deleted by another new region which shares a boundary. Once I have created the individual regions, I unlock all and delete the lines and the original grouped hole element.
Other ways to do it:
Brilliant, Barry, you ve just made my day. The explanation is crystal clear and the gif is just the cherry on the top.
many thanks Barry
No problem, happy to help.
