Parts to be enveloped

In this area, parts to be enveloped are listed/selected. After calling the function, the active object will be shown here. This can be a single part, an assembly parts of a part selection or all parts of a drawing. To remove parts from the list, right-click the desired item and select Remove element(s) from list. Multiple selections are also possible.

To add further parts to be enveloped, click the Select part icon and select the desired parts from the in the ICN or in the drawing. The parts highlighted in the part selection will also highlighted in the drawing (Special colour "Preview"). If you select an already marked part again, the marking will be removed, and the part will be removed from the list.

After selecting all desired parts, press the middle mouse button. This will take you to the next dialogue step, namely, the selection of the axis.

If you want to delete the originals after creation of the envelope, activate the Delete original parts checkbox.

If you select the Translation option beneath Form, the additional Allow holes checkbox will be available. If you activate this checkbox, holes (e.g.bores) in the original will be considered for the envelope as well.

 

General

Envelopes are solids and can be referenced, processed via their feature, or set to BOM-relevant via the corresponding checkboxes, like all other parts.

By default, HiCAD will enter the the name Envelope_n in the Article number field, with n being a consecutive number. If you want to use a different name, overwrite the default entry.

 

Form

In this area you specify the form and size of the envelope. Concerning the specification of the form, please note the following:

Origin
The start point of the direction vector will be placed in the origin of the active coordinate system.

X-, Y- and Z-axis
The corresponding axis of the active coordinate system will be selected.

Step back
Jumps back one step (if possible).

Cancel
Cancels the functions without creating the envelope.

 

The different options are explained in the following example. The assembly on the left (Pinion assembly) is to be enveloped.

(1) Original, (2) Cylindrical envelope, (3) Bounding box, (4) Translational envelope (in the image the property "Transparent" has been assigned to the created bounding box)

Cuboid

Required data:

  • Direction 1
    This is the direction of the displacement. Click the symbol and specify the displacement direction of the cuboid - either by selecting a line or by specifying 2 points. The selected direction will be indicated in the drawing by an arrow.
  • Direction 2
    This is the direction for the marking off of the cuboid width. Click the symbol and specify the displacement direction of the cuboid - either by selecting a line or by specifying 2 points. The selected direction will be indicated in the drawing by an arrow.
  • Direction 3
    This direction (length) will be detected automatically.
  • Offset
    For all directions an offset can be specified to change the size of the envelope. Positive offset values will cause a downsizing of the envelope.

 

Cylinder

Required data:

  • Select axis
    Click the symbol and select the cylinder axis - either by selecting a line or by specifying 2 points. The selected axis will be indicated in the drawing by an arrow. In the dialogue window, the previous text Select axis will change to Axis.
  • Diameter
    Specify the diameter of the cylinder or activate the Automatic checkbox if you want HiCAD to calculate the value automatically. If you chose the automatic calculation, HiCAD will use the smallest cylinder that completely envelopes all selected parts.
  • Offset
    Here you can specify an offset to change the height of the envelope. Positive offset values will cause a downsizing of the envelope.

 

 

Translation

Here you can create translational envelopes in up to 3 directions, the average value of which will then be calculated.

Required data:

  • Direction 1

This direction is the first translation direction. Click the symbol and specify the translation direction of the cuboid - either by selecting a line or by specifying 2 points. The selected direction will be indicated in the drawing by an arrow.

  • Direction 2 / Direction 3 (optional)

Here you have the option to specify further directions. To do this, you need to activate the options first. Then, click the symbol and specify the direction of the translation.

  • Offset

For all directions you can specify an offset to change the height of the envelope.

HiCAD will first create one envelope for each specified direction and will then calculate their average value.

Please note:

Here, the additional checkbox Allow holes is available. If you activate this checkbox, holes (e.g.bores) in the original will be considered for the envelope as well.

 

 

Manual/automatic - Process sketch

For each of the three defined directions you have the option to process the sketch on which the corresponding extruded envelope is based. For this to happen, you first need to click the Preview button.

Click the Manual/Automatic radio button for the corresponding direction, and then, click the Process sketch symbol. The corresponding sketch and the following dialogue window will be displayed:

You can now process the sketch with the Sketch functions. After completion of the processing, confirm with Apply sketch. The envelopoe will then be adjusted accordingly.

 

Buttons

After completion of all required input, continue by clicking on one of the following buttons:

Preview

Activates or ends the preview.

OK

Creates the envelope and closes the dialogue window.

Apply

Creates the envelope, while the dialogue window remains open.

Cancel

Closes the dialogue window without creating the envelope.

 

Please note:

If Part 1 is enveloped in the example shown below, the envelope will be located on the same structure level.

If Parts 3 and 4 are selected, the envelope will be located on the same level as Part 3:

If Part 1 and 2 are selected, the envelope will be located on the same level as Part 1:

Please note that the envelope will be hidden during processing. It will only be redisplayed after clicking the Preview button.
