Comment

Text in comments follow the general rules for formatting of posts with a minor difference when it comes to checklists.

Attachment pop-out

If you left click on the image of an attachment you open the image pop-out

Navigate between images from different comments in this topic with the left/right navigation arrows

Click download to download the image (you cannot right click the image to save it)

Pin the image pop-out on with the pin icon on the top right to keep the image pop-out open while navigating to other parts of Catenda Hub.

Close the image pop-out by clicking on the x top right, clicking on close bottom right or pressing esc on the keyboard.

A comment can have one of the following 3 attachments:

Adding an image to a comment

You can either click the plus next to the comment box and image to choose an image from your local hard drive or copy-paste an image to attach it to the comment. This option is always available.

Connect image to 3D

When you add an image to a comment it will say "No viewer connection" under the image unless you load a model in the 3D viewer. This text will then say "Connect to 3D viewpoint". You can now connect it to objects and a position in the viewer.
If you submit this comment you will be able to play back the viewpoint by clicking on the play button. Please make sure to add your annotations after connecting to 3D.

Image pop-out

The image that is attached to the comment after the comment is submitted can be popped-out to see a its contents in a larger format and download it after it has been submitted.

Deleting an image from a comment

You cannot edit or delete a picture that is attached to a comment.
If you want to remove the picture from the topic you will have to delete the whole comment.

2D or 3D snapshots

Adding a 2D or 3D snapshot to a comment

If you have a model loaded in 3D you can attach a 3D snapshot to your comment.

If you have the 2D viewer opened up you can attach a 2D snapshot to your comment.

The size of the image that is attached is dependent on the size of the viewer and the browser zoom percentage.

Snapshots are the best way to create high quality images or renderings from the Catenda Hub viewer for the following reasons:

  • Snapshot images can be downloaded from the attachment pop-out.

  • Snapshot images can have higher resolutions than just taking a screenshot from the viewer.

  • Snapshot images have transparent backgrounds. With 3D snapshots the image only contains pixels where there are objects in 3D. With 2D snapshots the image only contains pixels where there are lines in 2D.

This is what a 3D snapshot can look like. 2D snapshots will have the same buttons but with an image of the 2D viewer attached.

The amount of pixels in a snapshot image depends on the size of the viewer, the browser zoom percentage and your operating system display scale.

The largest image I have been able to generate so far has been 6417 pixels by 11113 pixels. To make a snapshot this big I had the following settings:

  • 4K monitor display.

  • Content panel and 3D panel visible.

  • Content panel as small as possible.

  • Browser in Fullscreen.

  • Browser scale 10%

  • Display scale in Windows 100%

These settings are very heavy on the system and your pc might not be able to handle this so you might have to tweak the these settings to fit your specifications.

Snapshots contain information about the time when you created the snapshot.

If an objec was hidden at the time of creation, the object with that ID will be hidden when the snapshot is recreated.

If an object was isolated, the object with that ID will be shown while objects that are not isolated will be hidden.

This also reflects to any objects with new ids that might be added to newer revisions of the model.

Recreate snapshot

Snapshots are great for showing people what you are looking at as they will be able to recreate the same views not only within Catenda Hub but also within their environment.

Snapshots can be recreated by playing them both in Catenda Hub and in our plugins.

In Catenda Hub the snapshot will move the camera to the right place in our viewer.

In the plugins the viewer of the host software will display.

  • By clicking this button the snapshot will be recreated with the same model and latest revisions loaded in the 3D viewer.

  • The camera in the 3D viewer will move to the location set in the snapshot.

  • The clipping planes from the snapshot will be re-created

Recreate snapshot with original revisions

  • By clicking this button the snapshot will be recreated with the same model and original revisions loaded in the 3D viewer.

Set camera position - Move the camera to the position of the snapshot in the 3D viewer.

Models - Click here to load the models from the snapshot in addition to the models that already exist in the viewer

Shows how many models are loaded in the snapshot.

Selected objects - Select the objects, that are selected in the snapshots, in the 3D viewer.

Shows how many objects are selected in the snapshot

Hamburger menu - If the 3D viewer is open the model load menu will be available

  • The models that with a checkmark in this menu will be loaded when the snapshot is played.

  • The models with a plus in front of them will be added to the set of models with checkmark after hitting save.

  • The models with a minus in front of them will be removed from the set of models with checkmark after hitting save.

  • Depending of the object visibility settings of the snapshot added models might be completely hidden. Even if they are not visible you should see that they are loaded when the topic is played.

  • The models that are on when this menu is opened reflect the models that are currently loaded in the 3D viewer. In order to easily add/remove a set of models you can make a bookmark, play the bookmark, go to the snapshot, click on its hamburger menu and hit save in the model load menu.

  • If a model in your snapshot has the same IFCPROJECT GUID as a model in the models section the models will automatically be linked.

    Here is an article from BuildingSMART that describes how this is done in Revit https://user.buildingsmart.org/knowledge-base/ifcproject/

Image pop-out

The image that is attached to the comment after the comment is submitted can be popped-out to see a its contents in a larger format and download it after it has been submitted.

Deleting a snapshot

You cannot delete a snapshot that is attached to a comment.
If you want to remove the snapshot from the topic you will have to delete the whole comment.

Annotation

When an annotation comment is added to an topic the annotated document will automatically be linked in the related documents.

A comment with an annotation will have:

Gray annotation header

  • Name and revision of the annotated document

  • The page that the annotations are on

  • The amount of annotations on the page

Picture with a preview of the annotation in the document

Annotation comment

The annotation comment follows the general rules for formatting of posts with a minor difference when it comes to checklists.

Image pop-out

The image that is attached to the comment after the comment is submitted can be popped-out to see a its contents in a larger format and download it after it has been submitted.

New comment

If the topic has a snapshot in the 3D model viewer there are some icons in the snapshot.

Just like any picture, you can annotate the snapshot by clicking on the preview image.

  1. By clicking on the add button, you can add a 2D/3D snapshot or picture from your hard drive.
    The 2D/3D snapshot comes from the latest camera angle in the 3D/2D viewer. By opening the 3D button in navigation viewer. You can navigate your way through the model to the topic in question and pressing the add button choosing the 2D/3D snapshot and then the snapshot will appear.

  2. If you left click on the snapshot you have taken, you have the option to add annotations to the image. Under the image a toolbar will appear with the tools to draw the specific point of the topic in more detail.

  3. The text box besides the add button is to write a comment, mention people be typing @name or link to other topics by typing #link.
